Title: I-15 Project Neon in Las Vegas
Post by: roadfro on December 10, 2013, 12:51:16 AM
Lawmakers OK $100 million bond to help untangle the Spaghetti Bowl (http://www.reviewjournal.com/news/lawmakers-ok-100-million-bond-help-untangle-spaghetti-bowl) (Las Vegas Review-Journal, 12/9/13)

Quote
A state Transportation Department request for authority to use $100 million in bond proceeds to buy right-of-way for the Interstate 15 widening project called Project Neon won approval Monday from lawmakers.

The approval came despite questions and skepticism from some lawmakers about the public-private partnership the agency would enter as a way to speed construction and build the project in four or five years, with completion in 2020.
Quote
The project will be the largest in the agency’s history and could end up costing $1.3 billion.


Project Neon has been talked about for close to a decade now. It is the proposed upgrade of I-15 between Sahara Ave and the Las Vegas Spaghetti Bowl (junction I-515/US 93/US 95). This is the busiest stretch of interstate in Nevada, with about 250,000 vehicle trips per day.

Proposed improvements under Project Neon include: mainline I-15 widening, braided ramps and collector-distributor roads along this section of I-15, addition of HOV lanes on I-15, an HOV direct-connect flyover to the HOV lane on US 95, complete reconstruction/reconfiguration of the substandard Charleston Blvd interchange, new access to local streets via an HOV interchange and a new half-interchange (enhancing mobility into the growing Symphony Park shopping/entertainment/business district), new linkages between arterial roads parallel to I-15, and various other improvements.

The proposed construction method is a new one for NDOT, which would enter a public-private partnership in which the private partner constructs the improvements and maintains it for several years, while the state pays for it over time. Supposedly, this would allow NDOT to get these improvements done in a much shorter period of time rather than typical methods.

The state has been slowly purchasing needed parcels for a few years. I think this bond money would let them move forward more rapidly to obtain the rest of the right of way needed.

More details about Project Neon were made public earlier this year:


Details of massive Project Neon unveiled (http://www.reviewjournal.com/news/traffic-transportation/details-massive-project-neon-unveiled) - Las Vegas Review Journal, 6/10/2015
Quote
The pain commences early next year.

But when all that construction pain ends, the $1.5 billion Spaghetti Bowl interchange rehabilitation known as Project Neon not only will provide a smoother, safer transition between U.S. Highway 95 and Interstate 15 but will provide superior access to downtown Las Vegas, the resort corridor and nearby medical facilities.

The 3.7-mile overhaul of the state’s busiest freeway interchange and the region just south of it will be the largest transportation infrastructure project ever done in the state.

While all the final flourishes could take up to 20 years to finish, four phases that represent the meat of the project will be undertaken in the next four to five.

The article mentions pretty much all the upgrades I stated in the above post.

Note the price tag increase from 2013.

A firm has been selected to construct Project Neon

Kiewit named 'best value' builder for Project Neon (http://www.reviewjournal.com/news/las-vegas/kiewit-named-best-value-builder-project-neon) - Las Vegas Review Journal, 10/12/2015
Quote
A firm called Kiewit Infrastructure West Co. was named the "apparent best value" to build the major Interstate 15-Spaghetti Bowl widening and improvement project called Project Neon at a price of $559 million, the state Transportation Board was told Monday.

The Transportation Department will now negotiate with the company to finalize a contract that could come to the state board for approval in November. The selection announcement was informational only.

The firm indicated that it expects to have substantial completion of the project by the fourth quarter of 2019, several months ahead of original projections.

...

The 3.7-mile overhaul of the state's busiest freeway interchange and the region just south of it will be the largest transportation infrastructure project ever done in the state when it gets under way next year. When all costs are tallied, including right-of-way acquisition, the project will reach an estimated $1.5 billion.

...

The project will improve safety and the state economy as commerce moves more quickly through the congested area. The section of freeway sees 250,000 to 270,000 vehicles a day with 1,000 crashes a year.

Interesting that the actual construction costs of this project are about $560 million, and there's a $1 billion in other costs. Much of that is likely due to this project involving significant right of way acquisition--the footprint of I-15 between Charleston Blvd and US 95 is probably more than doubling in width to accommodate mainline widening, new HOV flyover, and all the new braided ramp and C/D structures.

Also interesting that substantial completion is expected in late 2019. There's a lot of work to get done in what will likely be less than 4 years of construction time.

Wasn't I-15 through Las Vegas reconstructed sometime in 2008 or so? it added the express lanes.

There have been several projects on I-15 in the past decade or so, but none in the project area of Project Neon.

*I-15 North widening project - I-515/US 95 to Craig Road.
*I-15 Express lanes - 215 to Sahara
*I-15 South widening & C/D lanes - SR 160/Blue Diamond to Tropicana
*Resurfacing - roughly Tropicana to Sahara

Project Neon fills in much of the widening gap from Sahara Avenue to I-515/US 95, with numerous new structures to correct design deficiencies and eliminate many problematic weaving patterns.

Project Neon is scheduled to get underway in April 2016.

Project Neon begins in April with most traffic disruptions in 2017 (http://www.reviewjournal.com/news/traffic-transportation/project-neon-begins-april-most-traffic-disruptions-2017). Las Vegas Review-Journal, 2/9/2016
Quote
When Project Neon, the $1.5 billion, 3.7-mile Spaghetti Bowl-to-Sahara Avenue rehabilitation project, gets underway in April, it won't immediately disrupt freeway traffic.

In fact, crews won't close lanes of U.S. Highway 95 (I think they meant to say I-15) for the project until the first quarter of 2017 with the biggest disruptions planned from the third quarter of 2017 through the second quarter of 2019.
Quote
By July, work will begin on some of Project Neon's surface-street projects with the reconstruction of Martin Luther King Boulevard at the top of the list. Other surface street work will occur with the extension of Grand Central Parkway to Industrial Road and a high-occupancy-vehicle exit at Wall Street to be known as the "Neon Gateway."
<...>
Things will start to get messy for freeway users in the first quarter of 2017 when crews begin work on ramp-braiding projects, the additions of ramps designed to keep exiting freeway traffic away from vehicles merging onto the highway..

I-15 mainline improvements will occur from March to November 2018, avoiding high-traffic convention and holiday periods.

The most high-profile piece of the project will come last — construction of the high-occupancy-vehicle flyover connecting I-15 and U.S. 95 HOV lanes. That will occur from November 2018 through July 2019.

Glad to see this project finally getting underway.


I believe the biggest benefit of this project will be the braided ramps between US 95/I-515 and the Charleston Blvd interchange. This is a major cause of delay at all hours (but particularly the morning peak hour) as 2 lanes of heavy traffic entering I-15 from US 95 SB dump into an exit only lane for Charleston Blvd.

The reconstructed Charleston Blvd interchange also has the happy benefit of eliminating use of Martin L. King Blvd from the southbound ramp movements—and it intersecting Charleston entirely—which will significantly enhance surface street operations. By working on MLK first, hopefully there is some surface street relief in the interim while the mainline braided ramps and Charleston improvements are underway.

Another article from the RJ about Project Neon, which is breaking ground next week. Some repeated information, but one new tidbit I wasn't aware of...


$1.5 billion Spaghetti Bowl overhaul dubbed Project Neon begins next month (http://www.reviewjournal.com/news/traffic-transportation/15-billion-spaghetti-bowl-overhaul-dubbed-project-neon-begins-next-month)
Richard N. Velotta, Las Vegas Review-Journal, 3/28/2016
Quote
Well after April 7’s Project Neon groundbreaking ceremony in downtown Las Vegas, construction crews will be installing an active traffic management system, the first of its kind in the country.

“Essentially, we’re putting stadium-sized video boards over the freeways that provide next-generation, real-time information to motorists about detours, accidents and traffic restrictions,” said Nevada Department of Transportation spokesman Tony Illia.

The boards will be far more sophisticated than the existing dynamic signage that shows travel times to freeway exits and can be programmed to inform motorists of lane closures and blockages that occur with traffic accidents, Illia said. Signs will show the status of every lane as motorists approach the interchange that 300,000 vehicles pass through daily and sees 25,000 lane changes per hour.

This is the first I've heard of these traffic management video signs being part of this project. Sounds very interesting--potentially like full color/image DMSs.

From the way the article describes it, the initial boards will be spaced at roughly 1-mile intervals leading up to the Project Neon boundaries in all four directions approaching the Spaghetti Bowl interchange. And eventually these boards will be expanded further along I-15 (at least).

It's a "Car-nado"!!

That's the term NDOT has chosen to inform/warn the traveling public of traffic changes and potential delays around the Spaghetti Bowl as Project Neon work is progressing.

Car-nado set to wreak havoc upon downtown Las Vegas traffic (http://www.reviewjournal.com/news/traffic-transportation/car-nado-set-wreak-havoc-upon-downtown-las-vegas-traffic), Las Vegas Review-Journal, 10/27/16
Quote
Interstate 15 southbound and northbound ramps connecting to northbound U.S. Highway 95 will be closed every day until late February, according to the Nevada Department of Transportation.

Additionally, the I-15 ramps to Martin Luther King Boulevard will be closed during the same time frame as part of the $1 billion widening of the Spaghetti Bowl interchange known as Project Neon. About 300,000 vehicles travel daily on the Spaghetti Bowl’s looping ramps connecting I-15 and U.S. 95, with traffic expected to double by 2035.

...

The lengthy closures are needed so that crews can demolish a 22-year-old, two-lane bridge over Martin Luther King Boulevard that connects northbound I-15 to northbound U.S. Highway 95. The bridge will be rebuilt just north of its current location, making room for a flyover ramp that will be designated for high-occupancy vehicles.


The I-15 north to US 95 north two-lane flyover ramp has to be closed, in order to rebuild its bridge over MLK Blvd and realign the ramp's touch down point (this change is necessary shift lanes outward to make room for the eventual HOV flyover to touch down in the median of US 95). Since this is an extremely heavy traffic movement, traffic is being detoured on the longer single-lane ramp from I-15 north to MLK Blvd with a temporary connection to US 95 north upstream of the normal merge point. To facilitate the temporary connection, the other ramps mentioned have been closed.

I would anticipate that the 15 NB to 95 NB closure will produce some heavy delays. I'd estimate this is the second busiest ramp in the state (given that the opposite movement is the busiest), and is one of the (if not the most) predominant movement during evening rush hours at the Bowl. Even with keeping the one-lane detour, it will still be interesting to see how people cope with this...

Reading the link on my phone has everything jumbled up.  So I'm not really clear on understanding something, does that include the ramps to MLK near Charleston also?   If that's the case probably the best bet is try to avoid the interchange via Sahara.

Those ramps are considered part of the Charleston Blvd interchange, and are not affected at this time.

In later phases of Project Neon, MLK will be realigned westward to make space for I-15 mainline widening and new braided ramp structures to ease weaving on I-15 south between US 95 and Sahara, the Charleston interchange will be rebuilt as a diamond interchange, and the Charleston/MLK intersection will be eliminated with a new MLK bridge over Charleston.

If that's the case conventional wisdom might suggest jumping off US 95 at Drive and taking it south to Charleston to jump back on southbound at MLK then...vice versa for north bound.  But....then again, I would imagine most people during rush hour would be thinking the same thing and those ramps will likely be backed up more than usual.  Maybe Valley View and Sahara would be the better bet?  Wouldn't want to be stuck in that mess during rush hour that's for sure.

Looks like I got out of Las Vegas at the right time.  Was down there for a bowling tournament at The Orleans last weekend and usually head downtown to The Cal at least once during my visit.  Normally that involves me using I-15 to US 95/I-515 but this year I bailed at Charleston because traffic on I-15 was all backed up.

In the next phase of Project Neon, NDOT will be endorsing the "Zipper Merge" concept:

NDOT plans for motorists to ‘zipper merge’ into next phase of Project Neon (http://www.reviewjournal.com/news/columns/road-warrior/ndot-plans-motorists-zipper-merge-next-phase-project-neon) - Las Vegas Review-Journal, 2/26/2017
Quote
For the first time, NDOT will officially endorse “zipper merging” next month as a way to keep traffic moving when U.S. Highway 95 is narrowed to two lanes in each direction between Rancho Drive and the Spaghetti Bowl interchange in downtown Las Vegas.
(...)
Drivers will have plenty of time to get used to this method of merging. U.S. 95 will be reduced to two lanes each way through December as part of Project Neon, a $1 billion effort to redesign and add traffic lanes from the Spaghetti Bowl interchange to Sahara Avenue.

The zipper merge is being promoted as part of the next major project closure...

Next phase of Project Neon will put ‘The Big Squeeze’ on Las Vegas motorists (http://www.reviewjournal.com/traffic/next-phase-project-neon-will-put-the-big-squeeze-las-vegas-motorists) - Las Vegas Review-Journal, 3/1/2017
Quote
“The Big Squeeze” will elicit a long, painful pinch starting March 21, when U.S. Highway 95 will be narrowed to two lanes in each direction between Rancho Drive and the Spaghetti Bowl interchange through the end of the year.
(...)
“This isn’t like the other closures you may have encountered before,” Illia said. “This is a little longer, and a lot more significant.”
 
Through December, the major highway lane restrictions will coincide with periodic closures along nearby freeway ramps and surface streets.


Although Project Neon is primarily designed to improve flows on I-15, "The Big Squeeze" part of the project is closing the inside lanes on US 95 in order to construct a new HOV flyover between US 95 to the west and I-15 to the south. This flyover will connect the existing HOV lanes that terminate just west of the Spaghetti Bowl interchange on US 95 to I-15, where I believe it is eventually planned to convert the two existing I-15 express lanes to one HOV and one general purpose lane once the overall Project Neon is completed.

In the next phase of Project Neon, NDOT will be endorsing the "Zipper Merge" concept:


I didn't even know the Zipper Merge was a thing until I moved to Portland from Vegas. Used to think everyone who went all the way to the end of the merge lane was a complete a-hole. But I'm now convinced that it's effective and considerate.

Of course, so many people have moved to Portland in the last two years that the Zipper Merge is quickly becoming a lost art.

"The Big Squeeze" element of Project Neon is already underway. It's now expected to last until January 2018.

Las Vegas Review-Journal, 3/15/17
Quote
Thousands of downtown Las Vegas commuters have until 9 p.m. Monday [3/20/2017] to brace for a long, painful pinch known as “The Big Squeeze.”

That’s when U.S. Highway 95 will lose a traffic lane in each direction between Interstate 15 and Rancho Drive, a narrowing that will last through the end of January 2018, the Nevada Department of Transportation announced Wednesday morning.
<...>
The heavily used highway will be narrowed to two lanes so that crews can split the northbound and southbound lanes by roughly 70 feet. That will create enough room to build a new, 81-foot-tall flyover ramp for high-occupancy vehicles. The carpool ramp will have one lane for drivers headed from southbound U.S. 95 to southbound I-15 and another connecting northbound I-15 to northbound U.S. 95.

The page has a video that shows what the phasing will look like, shifting all traffic to one side of US 95 while the mainline lanes (and new bridges over Martin L King Blvd) are moved outward to make space for the eventual HOV flyover to touch down.

There's also some photos from the press conference, one of which includes the signage that will be used to encourage zipper merging.

After this phase of the project began, a significant change was made to the temporary traffic flow on northbound 515/93/95 just before the I-15 junction:

When the lane reductions began a couple of weeks ago, the left lane on north 515/93/95 ended at Casino Center, forcing traffic into a merge. But when I went through a week later, the configuration has changed so that the left lane no longer ends. Instead, lane #3 is now an exit-only lane for I-15 north (it wasn't that way before), leaving two lanes continuing past I-15 but now much more smoothly.

This seems to have made a big difference, and I don't think this was necessarily what was first planned.

That's a result of the "US 95 north" message block being horizontally centered on the sign. I'm pretty sure that sign has been in place since the Spaghetti Bowl was reconstructed circa 1999-2000...

However, commuters can still expect a series of lane restrictions and ramp closures around the Spaghetti Bowl until construction concludes in summer 2019.

40% seems like a bit much. There's still the HOV flyover, mainline I-15 widening, and several ramps to do. But I haven't been down there since beginning of summer (and there are some aspects, like "The Big Squeeze" where crews are frequently working more than one shift per day) so I could be mistaken...

Speaking of Neon signing, looking at the sign plans for Project Neon, it's disappointing that the Henderson / Boulder City BGS appears to be on its way out. I mean, that's 10% of the state's population.

That's got to be one of the more oddly-signed interchanges in the country. Three of the four control cities aren't on their signed routes (15/Los Angeles, 95/Reno, 93/Phoenix). Two of the control cities are 400+ miles away.

Bump, to post this article:

Third major freeway closure for Project Neon starts in March (https://www.reviewjournal.com/traffic/third-major-freeway-closure-for-project-neon-starts-in-march/), Las Vegas Review-Journal, 1/8/18
Quote
Are you ready to grumble?

The “Main Event” debuts in March, promising to land a final blow on commuters with a series of freeway ramp closures and lane restrictions in downtown Las Vegas, the Nevada Department of Transportation said Monday.

“We’re calling it the Main Event because this will be the biggest and most impactful phase of Project Neon,” NDOT spokesman Tony Illia said, referring to the $1 billion effort to redesign and widen Interstate 15 from the U.S. Highway 95 interchange to Sahara Avenue by July 2019.

(...)

NDOT anticipates three restrictions will have the largest effects from March to November:

— The ramp connecting southbound U.S. 95 to southbound I-15 will be reduced to one lane;

— The ramp linking southbound U.S. 95 to northbound I-15 will remain closed;

— Both directions of I-15 will be narrowed to three lanes between Sahara Avenue and Washington Boulevard, then further reduced to two lanes each way in the area immediately surrounding the Spaghetti Bowl interchange.

Also in the fray will be several month closures of the various ramps at Charleston Blvd...

That SB 95 to SB 15 lane closure (a dominant movement during AM peak) and narrowing I-15 to two lanes at the bowl is going to be awful... Glad I'm not in Vegas to have to deal with that :)

Good for NV for posting control cities of large well-known cities that are on the way, even if the numbered highway doesn't take you there.  Good choice of control cities.

Pheonix and Reno probably a good indication of what will be I-11's destinations.

A public meeting on Project Neon last week indicates significant progress.

Project Neon results starting to show up around Spaghetti Bowl (https://www.reviewjournal.com/news/news-columns/road-warrior/project-neon-results-starting-to-show-up-around-spaghetti-bowl/), Las Vegas Review-Journal 1/29/2018
Quote
Looking past the traffic jams and fields of orange cones, tangible results are finally springing up from Project Neon.

Thirteen of the 28 planned bridges along Interstate 15 and U.S. Highway 95 were completed last year, with the remainder scheduled for construction through 2018.

And 14 of the 42 planned Active Traffic Management signs were installed around the Spaghetti Bowl interchange, with the first six digital displays expected to be switched on next month.
<...>
Keller said that commuters can expect further closures when Project Neon heads into the final stretch in 2019, when crews will reconfigure the area around Grand Central Parkway and Charleston Boulevard to create a new “Neon Gateway” with a walking path and public artwork.

The 2018 "Main Event" restrictions mentioned in my last post are noted here as well.

From what I saw at the meeting (I watched via Facebook Live), NDOT is reducing lanes on I-15 so they can rebuild the I-15 bridge over US 95. This bridge appears to date to original construction of I-15 & US 95, being one of the few bridges not touched in the late 1990s reconstruction of the bowl. A new bridge here may allow for more through lanes on I-15 through the bowl (possible future HOV lane), and may also provide space needed below for an additional future through lane on SB US 95 and/or the proposed City Pkwy interchange.

Well a year from now isn’t too bad! This will be very welcome. After this they need to focus on the 515 through downtown and preferably widen, reconstruct, and make the bridge higher than it is. Something needs to be done with it because it is aging and congested. Honestly other than the beltway project, Las Vegas is in pretty good shape with its freeways.

‘Main Event’ on I-15 through Las Vegas reaches halfway point (https://www.reviewjournal.com/traffic/main-event-on-i-15-through-las-vegas-reaches-halfway-point/)
Las Vegas Review-Journal, 7/6/18
Quote
The massive freeway closure known as the Main Event plaguing downtown Las Vegas is halfway completed, with a new round of closures expected through mid-November, the Nevada Department of Transportation said Friday.
<...>
And motorists will notice traffic lanes shifting west onto the new southbound lanes for I-15 between Alta Drive and D Street, allowing construction crews to continue building the reconfigured freeway, Packer said.

Crews demolished nine bridges and started work on 12 others since the mid-March debut of the Main Event, marking the third and final round of long-term closures associated with Project Neon, the $1 billion widening of I-15 between U.S. Highway 95 and Sahara Avenue.

Project Neon is 73 percent complete, with construction expected to wrap up by summer 2019, Packer said.

I'm down in Vegas for Thanksgiving, and the drive to mom's house from the airport took me through Project Neon northbound briefly today. Didn't get to explore too much, but definitely apparent that they're closing in on the goal. It seems like they're mostly finished with the northbound I-15 widening, but still have middle HOV ramps and some southbound work to do on the 15.

Caught quickly on my phone a pic of what is now the biggest set of APLs in Nevada:  I-15 North approaching US-95. Noted on the right, US 95 North exit portion of the sign that (1) they left off the "Blvd" suffix from "Martin L King", and (2) they left room to add an I-11 shield.(https://uploads.tapatalk-cdn.com/20181122/ba98d0f3e2f517681939c998f53fd653.jpg)

This is a great example of why I DESPISE the APL signs, The whole thing is disproportional, the EXIT & ONLY panels look like an afterthought, and the destination names are far too tiny! And speaking of the EXIT & ONLY panels, WHY aren't they present for the option lane as well, since both destinations on that lane do not continue along the mainline of this freeway? EVERYTHING to the right of lane #3 is an EXIT ONLY lane and should be signed as such, IMHO. I understand why there may be a need for APL, but if this is the future then the future SUCKS!

I had the same thought about the option arrow, it should have the exit only panels. Although I can understand the reluctance to pu them on there with it being an option lane...

Despite what it might look like in the photo, the destination legend is the standard size used on all freeway signs in Nevada. I think the graininess of the photo and/or size of the sign is distorting it here.

And Los Angeles, which I-15 does not got to. Not that it stops US 93 and Phoenix of course.

That Utah sign does make the Las Vegas sign look a lot better though. Speaking of these signs, it's been my observation that Las Vegas in the past had a very unique way of putting MLK's name on the highway signs, omitting the Jr. in the full name of the road. Now it appears they're omitting the Blvd part too.

The old signs on I-15 used to use “Henderson” for southbound US 95 (I believe) and “Reno” for northbound. Sometime around the signing of I-515 in the mid 90s, “Henderson” was changed to “Phoenix”.

The few pull through signs on US 95 itself used to say “Phoenix / Needles” for southbound and “Tonopah / Reno” for northbound. These have been shortened to the current usage, presumably to eliminate excess message loading and use of lesser-known cities.

These APL signs are way too large and ugly. IMHO, the existing E11 series of black on yellow EXIT ONLY panels could be expanded, by vertically lengthening to allow them to being used with consistent sized black APL arrows on the yellow background. Then, use of the small add-on EXIT & ONLY panels intended originally for retrofits could be prohibited on new installations. This could clean up a lot of these signs and make them more compact, proportional, logical & legible.

Post by: compdude787 on December 13, 2018, 02:10:01 AM
When it comes to APLs, the US really needs to take some cues from the Netherlands in how they do similar types of signs. For example, they don't always use the long straight arrow, but only when there's space. Also, when there's cases where there's two exit ramps close to each other, they do something like this: https://goo.gl/maps/XwqeERrTEHk It's a bit hard to explain in words, so that's why I linked to a picture. This example is on A4 just south of the interchange with A20 in Rotterdam. If you look around in GMSV on the Netherlands' freeways, you'll find plenty of APLs done right.

Oh, and there's no stupid "Exit Only" signage, which is really redundant on APLs. If a lane is shown with a right curve arrow (and not two arrows that split from one line), it's pretty obvious that it's exit only.

Pretty sure the only "Henderson" signs on BGS's were 1) On a vintage 1999 Henderson/Boulder City sign on NB I-15, and 2) On Flamingo at I-515. I think the old-school signs said Needles/Phoenix for SB and Tonopah/Reno for NB – Can't imagine they would have used Henderson since 1) Henderson was very small at the time, and 2) 515 didn't even reach Henderson until the early-to-mid 1990s.

The old signs I'm talking about would have been ones in place prior to the reconstruction of the Spaghetti Bowl (which was completed circa 1999). The supplemental sign you mentioned on I-15 NB wasn't there before the reconstruction, and I have this recollection that Henderson was moved off the main signs for the supplemental sign when the construction finished. The I-515 freeway made it to Lake Mead Drive by 1990 and down to Railroad Pass by 1994 (which is when 515 was finally signed), but even before that, following US 93/95 freeway however far it existed (and then jutting over to Boulder Highway) was always the primary way to get to Henderson—the original EIS studies for that leg of US 95 freeway referred to the project as the "Henderson Spur".

An I-515/US 95 viaduct widening/rebuild and some concepts has been looked at a couple times. There are a couple interchange improvement concepts under consideration currently, but I'm not sure that this will be the next priority.

The next major NDOT project in the Vegas area is likely going to be the I-15/Tropicana Avenue interchange rebuild. The Tropicana bridge must be replaced to allow I-15 widening underneath, and due to height clearances the flyover will also need replacing. Given the proximity of the interchange to the Raiders stadium, this project has moved up in priority.

There will not be any direct access to the stadium from I-15.

One gripe about the stadium is that it will be under-served with parking. I think they're expecting high amounts of people to arrive via walking (from nearby resorts, etc.), rideshare, and potentially buses/shuttles from outlying areas.

One gripe about the stadium is that it will be under-served with parking. I think they're expecting high amounts of people to arrive via walking (from nearby resorts, etc.), rideshare, and potentially buses/shuttles from outlying areas.
That is a shortsighted move, IMO. The stadium is right off of I-15, they should have included direct access from the interstate.

Article about the ATM (Active Traffic Management) signs being installed on I-15 & US 95 as part of Project Neon:

Las Vegas I-15 closures to be worth it when electronic signs go live (https://www.reviewjournal.com/news/news-columns/road-warrior/las-vegas-i-15-closures-to-be-worth-it-when-electronic-signs-go-live-1594258/), Las Vegas Review-Journal, 2/10/19

After enduring several full closures of parts of Interstate 15 for the installation of dozens of dynamic traffic signs, readers have inquired: ‘What are these ATM signs?”
<...>
A lot of the questions readers have concern how ATM signs differ from traffic signs currently in use around the valley.

Most signs on area freeways now show the time it will take to reach certain destinations, where a road closure or construction project is upcoming, or special messages ahead of a busy travel weekend, and most utilize one color.

There are different ATM sign types. Some have text and arrows. Others just have arrows. Different colors are available to point out lanes that are open (green) and lanes that are closed (red).

They are more sophisticated than the existing electronic signage. They can be programmed to inform motorists of lane closures and blockages, or changing speed limits, if needed.

Providing real-time information to motorists about detours, crashes and traffic restrictions, ATM signs enable lane closures to facilitate traffic flows around crashes.

After almost three years of gridlock, confusion and road closures, the “grand finale” of Project Neon, the largest public works project in Nevada history, is set to come early.

The nearly $1 billion 4-mile widening of Interstate 15 from the Spaghetti Bowl to Sahara Avenue is set for substantial completion May 16, a full two months ahead of schedule.

New US 95 to MLK offramp, two other Project Neon sections to open Monday (https://www.reviewjournal.com/traffic/new-us-95-to-mlk-offramp-two-other-project-neon-sections-to-open-monday-1654788/), Las Vegas Review-Journal, 5/2/19

A few side ramps and bridges constructed as part of Project Neon will open Monday next week:
*The reconstructed/widened US 95 SB exit ramp to Martin L King Blvd.
*The new Charleston Blvd EB slip ramp to Martin L King Blvd.
*A new bridge connecting Industrial Road over the railroad tracks to Grand Central Pkwy just south of Charleston Blvd (a new north-south connection)

Project Neon's substantial completion date is set for May 13th.

Looks like final paving has begun. This project should be mostly wrapped up in the coming weeks with the exception of punch list items.

TBH, the more and more I think about it the more I wish they would have kept the express lanes(two in each direction) and added a GP lane or two in each direction. We’ll see how everything plays out. I’m slowly turning in favor of managed lanes over HOV lanes which seem to how evidence against them of them causing more traffic with weaving.

A welcome article for many Vegas-area residents!

Project Neon’s orange barrels to be removed from Las Vegas freeways (https://www.reviewjournal.com/traffic/project-neons-orange-barrels-to-be-removed-from-las-vegas-freeways-1694271/), Las Vegas Review-Journal, 6/24/2019

After three years of cluttering the side of both Interstate 15 and U.S. Highway 95 during Project Neon, the army of orange safety barrels will soon make their exit.

The 4,500 polyethylene barrels associated with Project Neon, the nearly $1 billion 4-mile widening of I-15 between Sahara Avenue and the Spaghetti Bowl, will be removed from the roadways next week, according to Tony Illia, spokesman for the Nevada Department of Transportation.

“Since we still have nightly closures on I-15 for various items, we will still be taking nighttime lane closures in several areas this week and next,” Illia said. “We will have all barrels removed from I-15 medians and shoulders by July 1.”

With recent paving finished, Project Neon stands at 96% complete. I'm guessing most of the remaining activity is landscape/aesthetics and various punch list items.

The title of this article speaks for itself

Project Neon, now officially done, goes out with a bang in Las Vegas (https://www.reviewjournal.com/traffic/project-neon-now-officially-done-goes-out-with-a-bang-in-las-vegas-1822387/), Las Vegas Review-Journal[/], 8/8/2019

After more than three years of road closures, lane shifts and traffic jams, the $1 billion Project Neon is officially over.

The Nevada Department of Transportation celebrated Thursday with entertainment, refreshments and dignitaries at a “grand finale” event concluding the largest public works project in state history.

While Project Neon was anything but a party to motorists, it created new access points in downtown Las Vegas and added a much-talked about high-occupancy vehicle lane system.

The one remaining piece is getting all the new traffic management signs functioning.

The dynamic messaging signs allow for traffic flow control, real time speed limit sign changing and more. The signs are still not in service as testing is about to get underway. The signs must run glitch-free for 60 straight days, according to Transportation Department spokesman Tony Illia. It’s expected the system will be fully operational in October, [if] testing goes as planned.

The Active Traffic Management signs are posted all throughout the I-15 corridor, but also in all directions around the Spaghetti Bowl. These will include Nevada's first foray into dynamic speed limits.

There's a sign on NB I-15 in here that I found absolutely absurd.

Something like:

NV 159 (shield)
Charleston Blvd
Grand Central Pkwy
Alta Dr / Bonneville Rd

It was a lot of words for one BGS.

Yeah. While all text on that sign other than "Charleston Blvd" is smaller size than normal, it is still a big amount of text. The rest should have been on a supplemental roadside sign.

The signage along the same off ramp is surprisingly subpar as well.

I think it's great that they finished the while thing one year ahead of schedule!
