Quote from: kernals12How come they need that much clearance between the main lanes and the frontage roads?

The space is needed for various types of ramps to merge in/out of the freeway. Space is also needed for support pylons of any flyover ramps. Room is also needed for drainage, utilities, etc.

The city of Houston found that, with minor changes, the need for eminent domain takings on the NW corner of the rebuilt i-45/I-610 interchange would be eliminated

Seems like a no-brainer, honestly. Still a plenty wide curve and reduces project cost.
Travelled in part or in full.

Breaking news.... 
The Texas Transportation announced that FHWA has ended the pause on sections 3A and 3B, and authorized some pre-construction work to proceed on section 3C.

It was reported that extensive discussions between TxDOT and FHWA have taken place in the recent month and discussions are ongoing.

The project has been delayed at least 2 years due to the FHWA pause.

This discussion will be available in the video of today's meeting when posted, see the opening remarks.


Your photo isn't displaying. Also, I'm not seeing news of this anywhere?

Edit: I see it now,

So FHWA has let TxDOT go forward to some degree with every part of the downtown rebuild except for the part that would make urbanists happy?


No, all of 3 is a go - 3D is last because it's the most intensive and disruptive during construction.

LOL that is an understatement...I still cannot even imagine how hellish things are going to be during the construction... I am glad I live five minutes from downtown and don't have to use a freeway most of the time. Though I do cross IH 69/US 59...
I do really hope that there is an exit to better serve Franklin Street/Canal/Navigation/Harrisburg.  And some more (or rebuilt) overpasses or underpasses at those damn railroad tracks... UP is always blocking traffic from East End for hours...
I really feel for anyone who regularly uses the Pierce Elevated though
I love freeways and roads in any state but Texas will always be first in my heart

I think this is a product of the use-it-or-lose-it system of government budgeting. If they don't spend the money on this ramp and all the ROW acquisition it requires, then they lose the right to use those funds. This incentivizes wasteful spending.

Braided ramps.  These are likely going to be heavily employed.  Quite a few of them are beginning to take shape on the new Montana Ave Frwy in E. El Paso (US - 62/180).   The Montana Ave Frwy is only going to have a six lane cross - section, while personally believe they should have gone for eight.

Did the city and county do much exploration into using the Hardy Toll Road extension to provide alternate capacity to downtown from the north instead of I-45 expansion?  This would avoid the neighborhood impacts of I-45 expansion from downtown to I-610.  The Hardy was to use former railroad ROW that had the railroad relocated and mostly just industrial land that would be impacted by an expanded interchange at the south end of the Hardy Toll Road.  You might not be able to duplicate the exact amount of additional capacity, and there might be painful upgrades along I-610 in between 45 and the Hardy.  Would need about a mile of elevated roadway on 610 if you wanted to avoid taking any homes.

Right-of-way clearance is proceeding on the southwest side of the intersection of IH 69 and SH 288.

According to the press report when FHWA allowed some work to proceed, FHWA authorized TxDOT to proceed with design work only on this section. I'm thinking this clearance work was a contract in progress when FHWA suspended the entire project earlier this year, and this clearance is being allowed to proceed. Another building just west of the demolished building is fenced off and it looks like the interior is being gutted in preparation for demolition.

Where is all the congestion? 9 a.m. and only some local congestion around downtown. If you compare that with European cities, you'll see that almost the entire urban highway network will be jammed up at 9 a.m. on a Monday morning.



I was told that widening the Katy Freeway made traffic worse

Bobby5280

The widening of Katy Freeway did not make traffic worse. There are two factors making traffic worse on Houston's West side. One: Houston is still adding a lot of new residents, thus increasing traffic levels. Two: they widened I-10, but they did nothing to improve the surface street network near the massive highway.

Bad surface street design is often the source of many traffic jams. If a primary surface arterial has frequent traffic signals and driveways from every property connecting directly to it that arterial will be very inefficient at moving large amounts of traffic. The interface between the surface street arterial and the freeway can be a very severe bottleneck. If the surface street sucks at moving traffic it will cause back-ups that accumulate over the off ramps and then back-build onto the freeway main lanes.

There is very little access filtering along the frontage roads adjacent to Katy Freeway. The same goes for the arterial streets crossing under I-10, such as Silber Rd or Antoine Dr near I-610 or Bunker Hill Rd and Gessner Rd closer to Beltway 8. The Memorial City and City Center zones around there can be a real nightmare. You have to drive farther West, nearly to Katy Mills, before more modern surface street grid designs begin to appear.

Houston was already a huge city before traffic engineers started incorporating methods of traffic access control along surface streets and in commercial or residential developments. A giant-sized, modern freeway built over the top of an outdated surface street grid isn't going to work as well as intended.

It's worth noting that the New Urbanists and other people who hate freeways don't see traffic as we do.  We think "the traffic is moving faster and/or it's stop and go over a smaller area and/or a shorter period of time" is good because it's less congested, but they don't - to them, less traffic means "overall VMT is lower".  To them, it's not traffic speed that's the issue, but the fact that people are driving at all, so more people driving, even if they're at free-flow = "more traffic" in their minds.  Those arguments would be met with "there would be less sprawl because the congestion discourages living out there"

Yep. They want everyone to live the way they think people should live.

I think the Katy Freeway example was also based on cherry picking data.

The Katy Freeway was reported to have had terrible congestion, with 10-13 hours per day of congested traffic flow, often in both directions. Nowadays it looks like it's not nearly as bad. And there are the express lanes which provide free-flow traffic.

Here's a photo of the Katy Freeway, pre-widening, from the Houston Freeways book:

Same thing with the 405. Though you could argue that was a waste of money too given they there are bottlenecks on both ends of the project extents that are the main cause of traffic backups. Part of me almost thinks that planners knew this and it wasn't going to help traffic to sour peoples opinions on freeway construction.

Also, note how they only focus on those two freeway projects only. If the Big Dig had made traffic worse, they'd be pouncing all over it.

Also, just a few years ago, New Jersey widened 35 miles of the turnpike to 12 lanes where before it had been 6 or 10. I haven't heard them claim that made traffic worse.

'They widened the freeway to 26 lanes and it only made traffic worse!'

Of course this is a misrepresentation of reality, but it makes for good headlines feeding into the confirmation bias of certain groups.

Though I think the average citizen doesn't really care or read about stuff like this. It caters to the Streetsblog type of readers I suppose.

Eeeee-yi. That is indeed horrible.

What I find fascinating is the ROW arrangement there, with the abandoned MKT/"Katy" rail line, the 2-way local road, the transmission line eavesment, and then the 6-lane I-10 with 2-lane access roads and single lane reversable HOV lane. That was a lot of spare room to clear to create the modern Katy Freeway/Tollway.

Wasn't there an alternative given that would have rehabbed the rail line as a light rail corridor in lieu of building the express toll lanes?

Well we've got a few politicians echoing that false belief

Quote from: Kernals12Who needs facts when you have a narrative?

Are you claiming to provide facts rather than your own narrative?

Apparently you breezed over what I said about Houston's old street grid design and how it contributes greatly to traffic snarls.

Quote from: Kernals12Also, note how they only focus on those two freeway projects only. If the Big Dig had made traffic worse, they'd be pouncing all over it.

No, the Big Dig made headlines with its massive cost overruns, tunnels leaking water and all sorts of other crap. By the time the project was finished some people thought it was a miracle the thing was completed at all. I guess 15 years after that 15 year long project concluded some people have apparently forgotten about the staggering costs and controversy involved.

If the Big Dig didn't do anything to make traffic worse in Downtown Boston it's probably only because it's such a pain in the ass driving into such a historically old street grid and trying to find affordable parking that no one wants to bother. Maybe we'll just party out in Worcester instead.

Quote from: Kernals12Also, just a few years ago, New Jersey widened 35 miles of the turnpike to 12 lanes where before it had been 6 or 10. I haven't heard them claim that made traffic worse.

The upper portion of the New Jersey Turnpike from exit 8 on North has had 4 carriageways and 12 lanes dating back to the f***king 1980's. The widening down to exit 6 was finished almost a decade ago. Also, your tossing out something of an apples-oranges argument. The New Jersey Turnpike has a limited number of exits. It's also a very costly toll road most people avoid unless they absolutely have to get on it. And by the way the New Jersey Turnpike and feeders into it get jammed on a regular basis.

Its traffic volumes say otherwise.

Bobby5280

Quote from: RothmanNobody parties in Worcester.  Nobody.

I'd rather attempt partying in Worcester than trying to find parking in downtown Boston. If worse came to worse there are other places to visit in the region. Springfield, Providence, Hartford, Concord, etc.

Quote from: sprjus4Its traffic volumes say otherwise.

They're bent over the barrel, not having much of any other choice. I guess there's route 1, but, oh well.

New Urbanists never show any interest in nuance, so neither do I.
