TxDOT starts process for IH 45 full 3x3 Houston-Dallas
« on: May 28, 2020, 01:51:12 PM »

http://ftp.dot.state.tx.us/pub/txdot/ppd/meetings/052620/presentation.pdf

Length: 90 miles. This appears to be all the remaining 2x2 highway (work on the 2x2 at Huntsville is separate)
Estimated cost: $2.5 billion,  $2.4 billion for construction plus $122 million for administrative
Timeline: Work included in the consultant contract runs through 2028, so actual construction probably starts in the 2030s

As per the current TxDOT standard, the proposed section is the 3x3 with no median, center concrete barrier and full inner and outer 12-foot-wide shoulders. The existing IH 45 has some "scenic" sections with wide medians having natural foliage, and I expect those to remain.

Iíve lived in Texas since 1985. During that time, there has generally always been construction on I-45 between Houston and Dallas. There was a brief period right before the started the Huntsville and Navarro County projects where I was traveling regularly between the two cities And where there didnít seem to be any roadwork. That cannot be allowed to happen again  :)

Not greatly familiar with corridor, having been on it perhaps once.   Guessing this does not include full bridge replacements, rather rehabs and "going" into the median for the third lane in each direction.   So not a full reconstruction, a rehab and widening.

Older bridges will likely be replaced in full.

Hopefully TxDOT has plans for a similar treatment on I-10 between San Antonio and Houston.

I-35 has already gotten 6 lane widening between Hillsboro (I-35E/W split) and San Antonio plus the SH-130 Austin Bypass.

I wonder if that is all done now. There was a section near Waco that they were working on last year. I probably should have been paying more attention, but I remember most of it being 3-lanes.

I avoided Waco on my drive through there last year due to heavy congestion and took SH-340, but I believe it's already 6 lanes through there presently, and is currently being widened to 8 lanes. The root cause of the significant traffic on-going (outside COVID) through there is the fact it's reduced to 4 lanes (2 lanes each way) for an extended period. This will not be a permanent problem once 8 lanes are complete.

I believe it's scheduled to be completed in 2023, with a possible early completion date in 2022.

I'm virtually certain everything is going to be rebuilt from the underground up, like they are doing now on IH 45 south of Huntsville and on IH 10 west of Houston. I drove on IH-10 last week, and they have shifted traffic to the frontage roads and have totally ripped out all the original mainlane pavement. There was a small mountain of broken-up concrete where it was collected.

On IH 45 that is included in this planning effort, all of the pavement is original (or overlaid with asphalt). This work will start 2030s, and TxDOT is surely building it to last to 2100 and beyond, so I don't think they will recycle any pavement or bridges.

The recent expansion to 3x3 south of Corsicana retained the existing pavement and expanded into the median, but the pavement was not original, it dates from the 1980s or 1990s.

Is limited-access maintained through there, or does the freeway effectively end through the work zone?

When I lived in DFW and drove to Houston a couple of times, I was surprised at how much south of Dallas was still 3 lanes. And it felt pretty busy too going down to 2 lanes even though the surrounding area was rural.

Are there other places with relatively short distance between 2 large population centers that you are surprised are still only 2 lanes per direction? San Antonio to Houston also has long range traffic on I-10, and are obviously 2 very large cities but thereís still a good bit of distance. Whatís it like between Cincy and Dayton?

Smaller example, but Baton Rouge to New Orleans is only 80 miles but mostly 2 lanes on I-10. Lots of bridges and the Bonnet Carret Spillway to build over, though. I just mapped the 4 lanes section and itís actually 54 miles from the southernmost Baton Rouge exit to the I-310 merge in Kenner that puts it back at 6 lanes.

Atlanta, Georgia to Charlotte, North Carolina, are both 7-figure metro areas that are connected by I-85, approximately the same distance as Dallas to Houston.  I-85 is 2x2 most of the way, though all three states (GA, SC, NC) have plans in various stages of completion to widen their pieces to 3x3 or better.

I-64 Richmond to Hampton Roads.

Once current projects are completed, there will only be 29 miles of 4 lane remaining. As funding allows, the remainder will be expanded to 6 lanes.

The lowest AADT on that 29 mile segment is around 60,000. Widening is needed, especially during peak weekends.

The traffic volumes on I-45 are still relatively low on that stretch: mostly in the 32,000 - 37,000 range between Huntsville and Streetman.

It appears that the goal is to create a minimum of six lanes throughout the Texas Triangle on I-10, I-35 and I-45.

It looks like I-35 between Denton and the Red River will get 3 laned each way, and the NCTCOG (I think it was them) has said they'd like to see I-20 east to the LA line also get 3 laned each way.

Some of the bridges will have to be replaced as they are nearing the end of their useful life (most of that corridor was built in the late 60s/early 70's)
