I-35 Capital Express South Project
Projects
Project overview
The project will add two high-occupancy-vehicle (HOV) managed lanes in each direction along I-35 between SH 71/Ben White Boulevard and SH 45 Southeast. In addition, the project will include a southbound I-35 bypass lane that will allow traffic to bypass Stassney Lane and William Cannon Drive. Entrance and exit ramps will also be reconstructed and relocated. Pedestrian and bicycle paths will also be added.
Major impacts/activity
Stassney Lane bridge at I-35 will be fully closed from Friday, Aug. 1 at 8 p.m. to Monday, Aug. 4 at 6 a.m., so construction crews can set panels and install lighting, weather permitting. Both the northbound and southbound I-35 mainlanes will have various lane reductions between SH 71/Ben White Boulevard and Slaughter Lane, nightly from 9 p.m. to 6 a.m. A detour video is available here.
- During the nighttime closure, there will also be lane reductions on the northbound and southbound I-35 frontage roads.
- Additionally, both U-turns at Stassney Lane will be closed from Friday, Aug. 1 at 9 a.m. to Monday, Aug. 4 at 6 a.m.
