The bridge will be closed during the following times:
There will also be lane reductions on the main lanes and frontage roads in both directions.
The details

Drivers traveling westbound will turn right on the I-35 frontage road to access northbound I-35 or use the U-turn at Stassney Lane to head south.
TxDOT created a detour video to help commuters.
The project
Construction on the I-35 Capital Express South Project began in 2022. The total cost is $548 million, which was funded by the Capital Area Metropolitan Planning Organization and TxDOT, according to TxDOT’s website.
The project will add two high-occupancy-vehicle lanes, a southbound bypass lane and pedestrian and bicycle paths. TxDOT officials anticipate completing the project in late 2028.
