I-45 onramp closures coming

From the inbox:

The Texas Department of Transportation will close the Houston Avenue southbound and Allen Parkway eastbound entrance ramps to I-45 southbound on Friday, July 8 to begin construction on new ramps that will improve traffic flow and enhance safety.

Currently, motorists trying to reach I-45 southbound main lanes from Allen Parkway eastbound have to enter from the left or inside lane. This has slowed the approaching traffic on the freeway sometimes causing a bottleneck effect that backs up traffic. The new ramp will connect to the main lanes of IH 45 southbound from the right lane allowing for better flow of traffic along the corridor.

To make room for the new Allen Parkway eastbound entrance ramp to I-45 southbound, the Houston Avenue southbound entrance ramp to I-45 southbound and the connecting bridge before the ramp will also need to be reconstructed. The reconstructed bridge and ramps will provide more efficient and safer access to the I-45 southbound main lanes.

TxDOT will close the existing bridge and ramps on Friday, July 8 to facilitate the construction of the new structures. The Houston Avenue bridge will be completed in late September/ early October of this year and the Houston Avenue/ Rusk and Allen Parkway entrance ramps to I-45 southbound will be open in late November/ early December.

Below is a list of the closures for this project:

  • Total closure of the Allen Parkway eastbound entrance ramp to IH 45 southbound on Friday, July 8 at 7:30 p.m.. Detour during construction is as follows: eastbound on Allen Parkway/ Dallas, right on Smith St.,left on Jefferson St., and follow Jefferson to the I-45 southbound entrance ramp.
  • Total closure of the Houston Avenue southbound entrance ramp to I-45 southbound on Friday, July 8 at 7:30 p.m.and the Houston Avenue southbound bridge at Lubbock and at Rusk on July 8 at 7:30 p.m. Detour during construction is as follows: from Houston Avenue take a left onto Rusk St., right on Smith St., left on Jefferson St., and follow Jefferson St.to the I-45 southbound entrance ramp.

There will also be additional closures to prepare for the bridge and ramp construction at this location. TxDOT will close allmainlanes on I-45 southbound at I-10 beginning Friday, July 8 at 9 p.m. until Monday, July 11 at 5 a.m. Motorists will be detoured to IH 10 eastbound to US 59 southbound to IH 45 southbound.

See here and here for the background. This is the implementation of something we first heard about last February. This is going to be painful, but at least it ought to be done in a few months.

To clarify what is being effected, here are a couple of pictures. First, what is being closed:

I-45 onramp closures

The black arrows point to the two to-be-closed onramps. The green arrow at the bottom shows where you will need to go in order to get onto I-45 South from downtown. If you’re saying to yourself “but Jefferson isn’t even next to I-45, how do I get onto I-45 from it”, take a look at this:

I-45 Jefferson entrance

You have to stay on Jefferson all the way through downtown till you pass under US59, then east of Dowling Jefferson elevates and crosses over I-45, where it basically becomes the southbound service road. The actual entrance on to I-45 is down past Cullen Blvd, so you’ve got quite a ways to go, especially if your journey involved taking Houston Avenue. Those of you who work downtown and commute in via the Gulf Freeway, you have been warned.

There’s also more work being done on Allen Parkway.

After a seven-week hiatus for some special events along Buffalo Bayou, major work will resume July 11 on pedestrian and parking improvements along Allen Parkway, part of an $11 million makeover that’s shifted the travel lanes on Allen south.

Officials also confirmed plans to meter parking along the bayou, to encourage turnover of the spots.

“The majority of users are visitors that are walking and jogging, riding their bike, taking their dog to the dog run, etc.,” said Angie Bertinot, director of marketing communications for the Houston Downtown Management District. “The three-hour time limit should suffice.”

Houston Downtown Redevelopment Authority, which is closely aligned with the management district, is overseeing the Allen rehab project expected to be completed in late September.

Growing demand for amenities in the Buffalo Bayou Park spurred officials to redevelop Allen to add parking, and make crossing the parkway more pedestrian-friendly. Slowing down traffic on the road – notorious for speeders who mistake the parkway for a freeway – also was a goal, downtown and city officials said.

Prior to the work slowdown in late May, traffic on Allen shifted to its new configuration. The remaining work focuses on landscaping, irrigation and some road repaving, said Lonnie Hoogeboom, director of planning and design for the Houston Downtown Redevelopment Authority.

“Also between July 11 and Sept. 30, the contractor will be constructing the new sidewalks with safer connections between Buffalo Bayou Park … and the west end of Sam Houston Park,” Hoogeboom said. “Transplanted live oaks have already been relocated to this area.”

Can’t wait to see what it looks like. We just have to make it through the summer first.
