Project is a go again:

Good to see that the urbanists have not yet completely taken over.

I do hope TxDOT quickly makes good on its promise to provide replacement housing.

The FHWA has signed the agreement to allow the project to proceed, fully lifting the project hold effective immediately.

https://www.houstonchronicle.com/news/houston-texas/transportation/article/i-45-rebuild-txdot-houston-pause-lifted-17822603.php

It appears that no changes to the design and lane count are included in the agreement, although TxDOT has agreed to study possible reductions in right-of-way acquisition. Opportunities for ROW reduction are very limited. Most TxDOT obligations are related to housing replacement and relocation, flood control and pedestrian amenities.

This is good news. In the near term we will probably see the right-of-way acquisition move at full speed. The section of I-69 between Spur 527 and SH 288 is slated to receive bids in June 2024. The next project is slated for 2027. The project hold was 2 years, and the opposition effort has caused a much longer delay to the project. So large-scale construction is still many years in the future.

The Federal Highway Administration and Texas Department of Transportation announced Tuesday morning they had reached an agreement, similar to those TxDOT reached with Harris County and Houston in December, outlining various commitments related to the planned $9.7 billion rebuild of I-45 from downtown Houston north to Beltway 8. The agreement immediately lifts the federal pause placed on the project on March 8, 2021, and resolves the audit conducted by federal officials related to TxDOT's adherence to federal environmental rules.

Good to see that the urbanists have not yet completely taken over.

It seems the New Urbanists are creating a good bit of backlash.

Over in Europe there is a growing amount of political back-tracking in response to extremely angry public reactions over efforts to create "15 Minute Cities." That effort is New Urbanism pushed to another extreme. They're trying to completely ban automobiles in city centers. The efforts have created a logistical mess for everything ranging from construction projects to people to just trying to get to work.

I can speak from experience what a pain in the ass it is to haul a couple suitcases on a crowded subway train after landing at JFK Airport. It's essential to travel light when taking mass transit, but not everyone can do that. Many of us take for granted being able to haul a lot of things in our personal vehicles.

The "15 Minute City" ideology conveniently ignores the fact city centers serve a lot more purposes that just providing a place where upper class douches can live in luxury apartments. Many city center businesses rely heavily on customer traffic coming in from the suburbs and points beyond. I like visiting spots in downtown Oklahoma City; it's fairly easy to get in and out via automobile. And there is a decent amount of free or cheap parking. If I wanted to visit Bricktown but had to park clear out in Newcastle and take a bus the rest of the way into downtown I wouldn't bother visiting downtown OKC at all.

15 minute cities are just fantasy. One that the media embraced, without checking how realistic this is.

Paris was the first to come up with this fantasy, but only 12% of Parisians (those living in the municipality, i.e. the core city) actually commute to work in 15 minutes or less. The concept is completely out of touch with reality.

Not to mention in Houston. Although interestingly, the 2019 mean journey to work in Harris County was 29 minutes. In Paris (the city core), 55% of commuters have a journey to work of more than 30 minutes.

Also, if you're never going to venture more than 15 minutes from your house, why do you need to live in Houston? You might as well live in Johnson City.

[Bobby5280]

Having a short commute is one of the reasons why I live in Lawton. It's little more than a 5 minute drive from my house to my workplace. New York City has lots of things to see and do, but after living there for 5 years I was sick of it and couldn't wait to leave. I sure don't miss those commutes eating 2-3 hours my life Monday-Friday.

I'm suspicious of the people selling the "New Urbanism" thing. My impression is the lawmakers and other proponents are upper income elites who don't have to live the daily grind of riding city buses and subways. I can recall my days of living in NYC and how it was a status symbol of sorts for people to use a car service or at least take a cab from place to place rather than ride a bus or subway train. I certainly don't picture any of those elites freezing their asses off standing at a bus stop.

[The Ghostbuster]

I'm no fan of New Urbanism either (there is plenty of it here in Madison). I see it as trying to turn every neighborhood it is built in into "Manhattan". The New York City one that is.

No actually the point is that everything you need is within a 15 minute walk from your house so you do not need to use a car regulate.
As someone who lived in the UES of NYC, I had a car, and used it for out of town/weekend trips not M-F and it was great.
So no, the 15 minute is not some conspiracy.

In any event, I am firm believer in stop I-45 UNLESS the agree to cap the highway.
IMO, highways in the urban dense core should only be built if they can be tunneled or cut/covered or capped like I-93 in Boston.
So from what I see, this is a horrible and ugly plan that will continue to make Houston a laughable 'city' compared to real cities.

Unfortunately for you, looks like the current plan is a go.

The highway expansion will help to re-route I-45 and allow the substandard and narrow viaduct on the west side of Downtown to be demolished.

I imagine upon completion, traffic flow around the central core on the interstates will generally be smoother, and the highways will be more modern and safe.

[Bobby5280]

It's pie in the sky dreaming to think every urban freeway can be dug into a trench and capped. The Big Dig in Boston cost billions of dollars yet the tunnels aren't very long. They had all sorts of problems too with water seeping through the tunnel walls.

Trying to do cut and cover tunnels around downtown Houston would run into the same problems. Considering the fact Houston is far more prone to tropical storm strikes than Boston it's likely such cut-and-cover highway tunnels would flood.

It's ridiculous to build attractions such as Minute Maid Park in the downtown area yet expect the massive crowds to just ride a city bus or some nonsense. Houston already has multiple skyscraper districts in various parts of the metro. That's a reaction to workers moving farther and farther out from costly city centers that are too complicated and time-draining to visit. The New Urbanism ideology doesn't stop to consider how much time it actually takes to ride a bus or train. The ideology sure as hell doesn't consider the obscene extreme prices of housing in that Utopian urban center.

The total cost of the "big dig" was close to $22 Billion, as recalled.   Over the close to fifteen years of the project.  The original Artery, had it's southern section already tunneled, via cut and cover method, when it was actually discovered how atrocious the elevated section (circa '50) was going to turn out.  But it never had enough capacity, only 3 x 3.   The "new" cut and cover Artery doesn't have enough capacity, either, the third Harbor crossing to the Airport "saves" it to an extent.  It really should have been 5 x 5 in the main downtown section.   
Pork, grafts, and corruption plagued the "big dig" project, and while it was finally completed, it was multiple times more expensive, than if it had been done two decades before, in conjunction with, or immediately after hypothetical Inner Belt construction.   The single most glaring episode, was the falling of a concrete ceiling tile, that fell and killed a motorist in one of the "new" tunnels.  Turned out non galvanized rod had been used to hold the panels in place, instead of correct treated hardware elements for the enviroment.   

[Chris]

The Boston Big Dig cost seems like a bit of financial voodoo, the Wikipedia page about the project is also cluttered with figures, comparing 1982 dollars to 2007 dollars, with an 'as of 2020', and 'to 2038 with interest' figures put in as well. As if it is an attempt to get the highest score possible. This makes it kind of difficult to compare the Big Dig actual construction cost to other urban highway tunnel projects, such as M-30 in Madrid, A2 in Maastricht, Netherlands or A86 Duplex in Paris.

However it seems that putting urban freeways in a trench is an unfavorable idea in Houston due to flooding. They have planned to raise I-10 west of I-45 for that reason.

You can mitigate the flooding issues if you properly design the tunnels to include a system of pumps and bulkhead doors that automatically activate when the rain rate exceeds a given threshold for a specified period of time.

[Bobby5280]

I can just imagine how some massive bulkhead doors would work at the openings of freeway tunnels. Some clown looks up from his phone to see a tunnel door 1 second before he smashes into it.

[Rothman]

Big Dig cost $15B, rounding up.

[abqtraveler]

I can just imagine how some massive bulkhead doors would work at the openings of freeway tunnels. Some clown looks up from his phone to see a tunnel door 1 second before he smashes into it.

There would have to be some advanced signage with lights and closure gates to compel motorists to exit the freeway when the bulkhead doors are closed.

Alternatively, you could build I-45 at grade level, then cover it in a way that allows for development and park space to be built directly over the highway. That would reduce the amount of supporting infrastructure needed to minimize the flooding concern.

[Plutonic Panda]

They couldn't justify(in their mind) tunnels in downtown Austin; arguably the best places in the entire state that makes sense for them. There's zero chance tunnels are built here. We the approval just get this built while we can.

Max, do you know if there's any changes to the timeline? I would imagine it's been updated or should be soon.

[MaxConcrete]

Max, do you know if there's any changes to the timeline? I would imagine it's been updated or should be soon.

No new timeline has been released. There are multiple issues to be resolved, see https://www.houstonchronicle.com/news/houston-texas/transportation/article/i45-widening-deal-txdot-steps-17711664.php

I don't think a schedule can be made until agreements are reached for all the details.
As of now, two projects are scheduled
1. I-69 between Spur 527 and SH 288, $493 million, listed for bids in June 2024.
2. Interchange at I-10 and I-45 on the northwest side of downtown, around $1 billion, listed for 2027

No other work is scheduled, but most work is listed for the 2030s.

If agreements on oustanding issues can be reached, I think we could see a speedup and possibly building each of the three sections as single jobs, rather then piecemeal over long periods of time. Houston will get a new mayor next year. A supportive mayor will likely speed up the process, and an opposition-oriented mayor could cause more delays and other project difficulties.

[Anthony_JK]

There are below-grade trenched sections of I-69/US 59 just to the west of the South Freeway interchange. Not sure if they flood in heavy rain or hurricane conditions....but then again, no one needs to be out in the middle of a landfalling Hurricane Ike in the first place.

Two sections of the NHIP are scheduled to be ultimately capped: the segment of I-69/US 59/relocated I-45 adjacent to Minute Maid Park, and a segment of I-45 just north of the divergence of I-10 west heading towards the Katy Freeway. The city would have to find donors willing to pay for the caps, since that would not be considered "transportation needs" that would qualify for Fed-state interstate funding; perhaps the recent grant H-GAC received could be a down payment on that.

Also, the realignment of I-10 and relocated I-45 east of the Allen Elevated section would be trenched as well.

From what I have seen, they do have mitigation measures set to deal with possible flooding (natural swales, retention ponds, relocation of Buffalo Bayou, etc.

I still say that they should have kept and improved the Allen Elevated section instead of rerouting I-45 and saved a ton of money and time. But, it is what it is. I'm just relieved that the project is somewhat back on track....for now.

[Rothman]

Interesting that the caps are not eligible for NHPP funding at 90%.  Wonder why they wouldn't be considered bridges over the Interstate.  STBG Flex funding is used for multipurpose trails, so it isn't like eligibility for federal funding is that restricted (although there was a local engineer that got caught trying to pay for a dog park with federal transportation funding...).

So, I would think caps are eligible for either NHPP or Flex at 80% at least, depending on what is going on the caps. Anyway, the excuse of not being able to use 90% does not tell the whole story one way or another.

Shoot, even if this were totally true, it would be a ripe time to get Buttiegieg to change the eligibility.

Makes me wonder how CDOT paid for a school playground on the I70 cap project in Denver.

They flooded completely in IKE.  They flooded to a lesser extent from Harvey. IKE practically destroyed the freeway. 

That said, there are non-freeway surface streets for first responders to take.  The freeways maybe the fastest route with traffic, in a post-hurricane recovery, there won't be that much traffic out on the surface streets. Even with a few flooded places, the bigger problem EVERYWHERE immediately after a hurricane is debris and downed trees.

Disagree.

1.  You can tunnel, cut and cover, OR cap/sell air rights.
2.  You build Minute Maid so there is a large population living nearby that can walk/bike vs having to import 100% longer distance people.

That is absurd.  The project should never be approved until the highway has a plan to cap.  Just awful.

Are you kidding me?  Make it 5x5?  Absolutely not.
The goal was to ease congestion and the god awful blight of the highway, you do this with full 12 foot lanes, shoulders, and easy merges in a city not making a mega highway; especially when it is designed for local not thru traffic!

Also, the big dig cost so much because Boston is an old city with colonial era roads and pre 19th century utilities that were a mess.
This would not be an issue in Houston.
