Title: Reno Spaghetti Bowl
Post by: roadfro on January 13, 2018, 10:43:05 AM
Thought I had shared this previously... NDOT is in the beginning planning phases of making improvements to the Reno Spaghetti Bowl (I-80 & I-580/US 395 interchange). The project scope will also include associated improvements on I-80 between Virginia Street and Pyramid Way/SR 445 (so may also address limitations on the viaduct over the Nugget casino) and on US 395 from Moana Lane to N. McCarran Blvd.

Two public meetings have already been held, and three initial concepts have been developed. Planning and environmental studies expected to go through 2020.

QuotePlans to improve Reno's main freeway interchange saw extra mileage this week with the release of an early 3D video rendering of the Spaghetti Bowl Xpress project.

The Nevada Department of Transportation stressed that the bird's eye view rendering is preliminary and that "no design plans are finalized,"  according to Public Information Officer Meg Ragonese. At the same time, NDOT also wanted to give the public an idea of what the proposed improvements might look like as the agency continues to seek public comment about the project.

^^^^^^^
From the information provided by the video, it looks like the project is mainly aimed at improving SB I-580/US 395 traffic flow at and south of the I-80 interchange; the interchange itself, except for the EB>SB ramp, isn't seeing any major alteration (such as replacing the loops with flyovers). Since that interchange is now about 45 years old -- and the region has experienced quite a bit of overall growth -- it seems that a comprehensive interchange revamping -- including flyover construction -- would be appropriate (I've personally witnessed backups at the site, primarily with the NB>WB transition).  Just wondering if any such upgrade plans are being considered for the not-too-distant timeframe?

You might want to take another look at the original post  ;-)

NDOT is studying a comprehensive revamp of the Reno Spaghetti Bowl to include reconstruction of most major movement ramps at the interchange and modification of several service interchanges in all directions around the bowl. Three major alternatives have been presented with varying levels of complexity, with alternative 1 being the most ambitious (maintaining all current movements with a lot of ramp weaving and a greatly increased footprint of the bowl) and the other two alternatives being smaller in scale (with possible elimination of some ramps at surrounding service interchanges). The main project may also address the limitations of the Nugget viaduct on I-80 (mostly depicted in alternative 2). Planning for this project began in 2016, with two public meetings being held during 2017. They're looking at a final NEPA decision and selection of preferred alternative in 2020, with construction possibly being completed in as many as five phases after that point.


The video above is a rendering of the "Spaghetti Bowl Express" project ("SBX"), which is being billed as "phase 1" of the overall project and is to be implemented in the short-term. The SBX project is expected to address some of the most problematic issues in the existing Spaghetti Bowl: the EB I-80 to SB US 395 movement, as well as lane drops and weaving problems on SB US 395 SB between the I-80 overpass and the Mill St interchange. The SBX is expected to go to final design next year and construction in 2020, with a completion date of fall 2021.

OK -- hadn't gotten around to slogging through the NDOT "preliminary" PDF's; looks like the ultimate plan -- whenever that occurs -- is a full turbine interchange enhanced by provisions for local access.  The plans look pretty impressive.  Any rough idea about what the possible timeframe is for this interchange revamping?

Spaghetti Bowl has been included in one of Interstate Kyle's tour of I-580 from Carson City to Reno.

Last night, I went to a public hearing on this project. The Draft EIS identifies Alternative 2 as the preferred alternative, although there are some slight modifications from the original concepts. Construction would take place over five stages spread out over about 20 (!!) years, with Phase 1 still being the Spaghetti Bowl Express project mentioned previously, which is anticipated to go to construction in 2020.

Alt 2 would install a DDI at Plumb Lane and remove the direct ramps to the airport along I-580. The airport has a compromise proposal that would keep the southbound ramp. NDOT is looking for comment on that as well. (I would prefer to see both ramps kept, and am not so sure on a roundabout proposed at the airport main entrance...)

Probably the biggest impact from a traffic operations perspective is that Alt 2 would eliminate the 4th/Prater and Rock Blvd interchanges and replace them with an interchange at Kietzke Lane (with frontage roads connecting Kietzke to Rock Blvd). It would also connect Nugget Ave to Rock Blvd (which would provide Rock some access to the Pyramid Way interchange as well.

Apparently, NDOT/consultants have used a new style or format for this document that is supposed to be easier for the public to read and comprehend–I haven't looked yet to confirm. Public comment period on the Draft EIS runs through January 15, 2019.

I don't think the revised concepts have been uploaded to the project website yet.

The Airport Authority has gone so far as to put a Save The Ramp! page on their website:

https://renoairport.com/airport-authority/save-ramp (https://renoairport.com/airport-authority/save-ramp)

Most of the traffic into the airport uses that existing flyover ramp from southbound I-580.  My feeling is, if that's removed, several years later they'll think "Why the heck did we do that?" and will start the planning to add it back in.

Yes, this NDOT proposal seems to be an insane one. I have used that ramp on several occasions when visiting the area. The planners must either be out-of-state consultants, or don't care because being based in Carson City they always access RNO from the south. Or, perhaps, they're just cost-cutting (penny-wise, pound foolish) to eliminate an expensive to maintain flyover.

Looks like NDOT got smacked upside the head hard enough on this that the direct ramp from southbound I-580 into the airport has now been added back in to the project.  The direct ramp exiting the airport onto northbound I-580 is not going to survive though.

So it appears that common sense has regained the upper hand. That's good news for the driving public, especially those headed to RNO.
Title: Reno Spaghetti Bowl expansion (through 2039) gets federal approval
Post by: Kniwt on August 14, 2019, 07:56:08 AM
KOLO-TV reports:
https://www.kolotv.com/content/news/Federal-Highway-Administration-approves-Reno-spaghetti-bowl-improvements-540113561.html

QuoteThe Nevada Department of Transportation (NDOT) plan to improve the Interstate 80 / Interstate 580 interchange in Reno has received a key approval from the Federal Highway Administration (FHWA).

The FHWA approval of NDOT's Record of Decision / Final Environmental Impact Statement allows the project to move to the next phase.

The plan for the so-called Spaghetti Bowl redesign calls for:

- construction of higher-speed ramps
- adding additional interstate lanes in certain areas
- reducing merging and weaving at the interchanges
- enhancements to the interstate shoulder, landscape and other aesthetics

NDOT says, with federal approval in hand, the road improvements will be designed and built in phases through 2039 as funding is identified.

Project website: https://ndotspaghettibowl.com/
QuoteThe Department received three proposals from the design-build teams in May and spent several weeks evaluating them. Unfortunately, the proposals were either non-responsive or not cost effective. As judicious stewards of taxpayer funds, the Department elected to cancel the design-build procurement and advance the project using traditional design bid build delivery.

It's fair to say planning for Project Neon started in the early/mid 2000s, but actual construction activity (ROW clearing, etc.) started 3-4 years ago.

It's also worth noting that Project Neon was ultimately constructed with the design-build method, which sped up delivery. IIRC, NDOT was originally planning to construct it in separate phases using the traditional design-bid-build method, which definitely would have drawn it out over several more years. Apparently the design-build teams that submitted for the Reno Spaghetti Bowl weren't qualified enough for NDOT to move forward with that.

Well, the Final EIS has been approved, so that represents a bulk of planning completed. According to a recent article in the local paper, this FHWA on this EIS took 28 months, which is supposedly the fastest EIS process NDOT's ever had for a major project.

NDOT is fast-tracking the first phase (Spaghetti Bowl Express or SBX), which is going to start in 2020. I think NDOT was fairly committed to doing this part no matter what happened with the rest of the project.

On a semi-related note: it would be nice if we could get the EIS process to take around 12-16 months tops. Especially for major infrastructure projects of high priority.

Sure, it'd be nice. But if the primary goal of an EIS is to manage environmental and cultural impacts, the secondary is to avoid lawsuits.

And that takes time, so that potential litigants can have their say and have their claims analyzed so that they don't end up spending years in court — because the data was already looked at and is ready-made for a judge to consider.

So when you're looking at ensuring there's no significant impact to tribal resources, endangered species, Title VI communities — you essentially are doing the prep for the lawsuit before it's filed, in hopes that through the prep the lawsuit never gets filed.

Because in most cases, if you have a project that requires an EIS? Without that kind of analysis you're guaranteed to have someone suing you.

The Reno Gazette-Journal reports on a significant setback for this project: The cost of the first phase has risen to $223 million, and federal funding has been lost:
https://www.rgj.com/story/news/2019/12/09/reno-spaghetti-bowl-xpress-project-losing-federal-funding/4354180002/

QuoteThe cost of the Reno-Sparks Spaghetti Bowl Project just got higher. Much higher.

The state is looking at a significantly higher price tag as well as the loss of $95 million in federal funds for the first phase of the Spaghetti Bowl reconstruction after it accepted a new unsolicited proposal to move the delayed project forward.

The first phase of the project – dubbed Spaghetti Bowl Xpress – is now expected to cost $223 million, according to the Nevada Department of Transportation and Regional Transportation Commission of Washoe County. The original amount that NDOT quoted for the project was $150 million. A recent decision by the Nevada State Transportation Board of Directors to accept a joint unsolicited bid for the project without seeking competing proposals also means that it no longer qualifies for federal funding.

More components of what I'm guessing is still part of phase one are beginning:



QuotePer NDOT:

With more than 250,000 drivers traveling through the spaghetti bowl every day, the Nevada Department of Transportation is giving motorists a look ahead at spaghetti bowl construction and reminding drivers of options to keep updated on ramp and lane closures.

Launched in summer 2020, the Spaghetti Bowl Xpress project has already reconstructed aging concrete on northbound I-580 near Mill Street.

As construction continues through 2022, drivers will see ramp and lane closures and shifts at the spaghetti bowl, as well as on I-580 and side streets between the spaghetti bowl and Villanova Drive.

In 2021, construction will largely focus on reconstructing and widening eastbound I-80 to I-580 spaghetti bowl ramps, as well as realigning Mill and Second street ramps for enhanced access to and from southbound I-580. Neighborhood wall installation and utility work will also take place.

As a reminder here is the project website: https://ndotspaghettibowl.com/

I believe this is still phase one just new construction components starting. NDOT states improvements and will continue through 2040. Maybe that timeline will be expedited. I like Reno and I'm going there more and more and to me it looks like besides the interchange itself nothing is in dire shape or extreme traffic. I'm glad to see more work here starting.

Yes this is still phase one of the overall five phases of the Reno Spaghetti Bowl project, referred to as "SBX"  (Spaghetti Bowl Express).

The construction that started in the fall was the work to replace aging concrete in the northbound I-580 lanes (which I'm still surprised they didn't do years ago in conjunction with the I-580 northbound widening in the previous decade). That work is still ongoing, but the most disruptive part for traffic (involving a temporary split to accommodate paving in what was essentially the #2 & #3 lanesj has concluded.

In late November/early December, the first visible work on the capacity-improving elements of the SBX project began. This includes shoulder work along southbound I-580 south of the Bowl  (which appears to be for future widening), as well as earthwork adjacent to part of the existing 80 EB-to-580 SB ramp for its realignment.
Title: Re: Reno Spaghetti Bowl
Post by: roadfro on March 20, 2021, 02:03:38 PM
The SBX project is well underway now, and this past week began a phase of construction NDOT is calling "The Big Squeeze"

Major Traffic Change Known as "Big Squeeze" Begins Tomorrow as Part of Reno Spaghetti Bowl Xpress Construction (https://www.dot.nv.gov/Home/Components/News/News/6830/395) (NDOT Press Release, 3/16/2021)
Quote
CARSON CITY, Nev. — Major Interstate 580 lane and merge changes dubbed the "Big Squeeze"  will launch the morning of March 17 as part of continuing Nevada Department of Transportation Reno spaghetti bowl improvements.

The "Big Squeeze"  name reflects new lane and merge changes that will "squeeze"  traffic lanes through the spaghetti bowl beginning at 6a.m. March 17 through spring 2022. The temporary lane configurations are needed for ramp and bridge improvements. Initially scheduled for March 12, the lane changes were rescheduled due to weather and are subject to change based on future weather.

March 17: The "Big Squeeze"  Begins at 6a.m. With New Lane/Merge Patterns —Subject to change based on weather
The following merge/lane switches will begin at 6a.m. March 17 and be in place through spring 2022:
  • Westbound I-80 to southbound I-580 traffic will merge directly onto I-580 lanes as opposed to the current dedicated merge lane.
  • Eastbound I-80 to southbound I-580 spaghetti bowl ramp will be temporarily reconfigured to one lane, with a dedicated lane to southbound I-580.
  • Southbound I-580 travel lanes will be additionally shifted directly south of the spaghetti bowl to make room for ramp improvements.
    (...)
    The improvements are part of construction of the first phase of NDOT's spaghetti bowl renovations, known as Spaghetti Bowl Xpress. Over the next two years, the eastbound I-80 to southbound I-580 Spaghetti Bowl ramp will be widened to two lanes and eastbound Interstate 80 lanes between Wells Avenue and the Spaghetti Bowl striped. On southbound I-580, auxiliary merge lanes and improved ramps will also be added between the Spaghetti Bowl and Plumb Lane, along with sound and aesthetic walls. The first phase of construction will not require relocation of any residences.

    Project information and sign-up for e-mail project updates is available at www.ndotspaghettibowl.com.
This squeeze will be a choking point for a while... In the existing condition SB US 395 already loses a lane approaching I-80, so that the WB I-80 to SB I-580 movement can have a dedicated lane. Under the big squeeze, that WB>SB movement will be an additional merge. That movement isn't the dominant movement at the interchange, but it's busy enough during the morning rush (along with the already existing heavy southbound flows from the north valleys) that it's likely gonna make morning commutes miserable for those from the north for a while.

The I-580 southbound lanes have been shifted just at the E 2nd St & Mill St overpasses for a few weeks now, as half of those bridges were torn down so they can be reconstructed to accommodate the wider southbound travel lanes. But now this is a long-term shift to the northbound lanes for the longer stretch between I-80 to past Mill St to additionally accommodate widening/realigning the I-80 ramps to SB I-580, widening bridges over 4th St and the Truckee River, and reconstructing/widening the main SB travel lanes.

Bumping for an update on the Spaghetti Bowl Express project:

This past week, a few nighttime closures paved the way (pun intended) for I-580 southbound traffic to be shifted to the west side of the roadway onto reconstructed bridges and newly-paved lanes built for the SBX project. The shifts should be complete tomorrow morning for what NDOT is calling a "sneak peek" of the ultimate improvements.

CARSON CITY, Nev. — Major Interstate 580 lane and merge changes dubbed the "Sneak Peek"  will launch the week of May 9 as part of continuing Nevada Department of Transportation Reno spaghetti bowl improvements.

The "Sneak Peek"  name reflects the fact that drivers will get a first look at newly-constructed interstate lanes as southbound traffic is switched to travel the new lanes while reconstruction continues in the interstate median.
<...>
Beginning at 6 a.m. May 16, southbound I-580 lanes between the spaghetti bowl and Villanova Drive will slightly switch to the right-hand, or western, side of the interstate. 

The new traffic configuration will place southbound motorists on three new lanes and five newly-widened bridges constructed over the past year and a half. Approximately 25,000 cubic yards of concrete was used to pave the new lanes.
<...>
Following the lane changes, the work zone will shift to reconstruct middle interstate lanes. Spaghetti Bowl Xpress renovations will substantially complete at the end of the year, with continuing lane and ramp closures through the end of the year.

Bumping to note that NDOT announced yesterday that the "Spaghetti Bowl Xpress" project is substantially complete. This included I-580/US 395 SB widening and ramp reconfigurations from the bowl to about two miles south, along with the widening of the I-80 EB to 580/395 SB ramp.

The roadway improvements themselves are good, and will be very helpful once local traffic has adjusted. Some of the new overhead signage is not the best quality.

Fingers crossed that this is just because the signs are still a WIP. Signage is one thing that is often still being worked on past substantial completion.

Nope, it's final signage. The project is basically done and they're just down to punch list items.

My main gripe is the new APLs on I-80 EB approaching 580/395. Text is oversized, and they used bubble interstate shields. There's also the new I-580 NB APLs, which are mostly ok except the use of "Sparks" as control city for I-80 EB instead of the more distant "Elko" (WB is using "Sacramento").

When I say we need to modernize control cities, this is ... not what I have in mind

Sparks and no Elko? At least go Fernley if you're going to mix things up. Ugh. Engineers.

The old NB signs used two cities: "Reno / Sacramento" for WB and "Sparks / Elko" EB, which was much better.

And now that I'm thinking about it and had a second look at them, the new NB APLs shouldn't be APLs at all, at least where posted...there isn't an option lane...

The new signs are indeed, um, not great. 36A shouldn't be an APL at all, 36B is confusing, and I hate using Sparks as a control city if the city line is spitting distance away. Photo is mine from October, 36A tab has since been added to the first assembly.

I will say that the improvement in weaving congestion along SB I-580 is very noticeable. Now if they could fix the crumbling concrete between Plumb and South Meadows...
