Texans working late will encounter traffic delays this week. The Texas Department of Transportation (TxDOT) is planning major nightly closures on I-35.
Beginning Monday, October 5, at 10 p.m., the northbound and southbound I-35 frontage roads at Howard Lane will close nightly in 15-minute rolling intervals. The construction site is in North Austin, near John B. Connally High School.
The shutdowns will last no more than 15 minutes. They will occur on a rolling basis in all directions, according to the agency’s post on X.com. Crews will work nightly through 5 a.m. Thursday, October 8.
It may prove inconvenient for some heading home after work or after-school activities. TxDOT says the closure is to allow staff to conduct overhead utility installations.
The closures are part of a larger initiative, the I-35 Capital Express (CAPEX) North Project, which the agency says includes adding “one high-occupancy vehicle managed lane in each direction along I-35 between SH 45 North and US 290 East.”
“In addition, the project will reconstruct bridges, relocate and reconstruct entrance and exit ramps, add a diverging diamond interchange (DDI) at Wells Branch Parkway, add pedestrian and bicycle paths, and make additional safety and mobility improvements within the project limits,” TxDOT’s website states.
The large-scale expansion is expected to be completed in early 2029.
