Sorry, Iím not familiar with Houston much, why is the Pierce removal bad?

It's not, but roadgeeks.

Removing the Pierce Elevated structure on the Southwest side of Downtown Houston would make it easier to revitalize run down parts of the Midtown district. When you get on the other side of the Pierce Elevated from downtown there is a fair amount of run down property.

Maybe one of the long term goals is for Downtown Houston to grow to the Southwest toward Museum Park and the Medical Center district with its own collection of skyscrapers. Of course I can predict anti-freeway types to start campaigning for the removal of the aging I-69 elevated freeway from West of the TX-288 interchange to the TX-527 spur. But that particular freeway segment needs to be expanded rather than deleted.

It's being sunk below grade as part of this project. Long term, it will likely have a cap put on it. But I don't think any expansion will ever happen. Urban freeways are congested; that's just how it is.

Looking at streetview and the plans to accommodate more traffic on existing freeways, this seems like a good plan and could help expand Houstonís CBD to have a larger footprint.

That's the first I've heard of that section of I-69 being included in the massive I-45 re-routing project downtown. I thought that project started in the vicinity of the I-45/I-69/TX-288 interchange on the South corner of downtown and then going around the East and North sides of downtown.

The current elevated section of I-69 from the TX-527 split to the TX-288 interchange is only 3 lanes in each direction. It's a fairly serious bottleneck. Just West of the TX-527 split I-69 expands out to 5 lanes in each direction, plus a reversible HOV Lane (in a trench for about a mile).

If they do put that 6-lane section of I-69 into a trench I hope they can make the road at least 4 or 5 lanes wide in each direction. I'm sure such a road would still be congested. But it would be stupidly ridiculous for TX DOT to rebuild that section of freeway in a trench and still make it only 6 lanes wide. They should add at least some additional traffic capacity for all that effort. I think it's completely possible such a road could have a decorative cap with green space and even some buildings built over the top of it. That could set up a long term situation for Houston's downtown to grow Southwest all the way to the Astrodome and NRG Stadium.

The only thing I don't like about freeways in trenches in the Houston area: flooding potential.

The below grade portion will have five lanes in each direction: http://ih45northandmore.com/docs9/20180521_NHHIP_Seg3_Overview_Layout_PH_1-1.pdf

As stated before, after this project, I don't see there being any further expansion.

The new connection ramp at 45 and IH 69 on the southeast side of downtown is proceeding well. It will be a long, high-flying ramp.

That's done on purpose. If it's going to rain a lot, you'd rather it flood a freeway than somebody's house.

As much of a pain it was for the Beltway to be shutdown after nearly a month Harvey due to drainage and repairs, imagine how many homes were saved because this massive volume of water was retained! IIRC, homes in this area still had about 3-4ft of water inside!

The parks and highways here are made to hold water. I don't understand why the media doesn't get that. I can't imagine any other city handling this much rain better than Houston did the last 3 major rain events. Sandy? Katrina? Neither we're nearly as much rain in such a short period...

The media doesn't get that because they're in the business of drawing your attention, and seeing your daily commute blocked by millions of gallons of water gets a whole lot of people's attention.

The Swamplot article below has some more photos and gives some details on the ramp. It also mentions a "glimpse" of the 45 downtown rebuild. How does this ramp fit into the total rebuild? Will this become the northbound connector to the new configuration parallel to 59/69?

I was told that it is designed to be compatible with the overall rebuild plan. The only potential non-compatible part is the end which dips into IH-69 trench. It may need to be razed to be repositioned.

Looking at the schematic and the existing design, it does appear that the current ramp lands too close to the middle of the trench, and the the landing position will need to be shifted westward. The schematic does not appear to indicate a radius change, so it is unclear how much of the west end would need to be rebuilt, but it will probably be between 500 and 1000 feet.

The ramp shown in the foreground of the photo below is now open, Tweet is shown.
