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
Northbound I-35 mainlanes between Slaughter Lane and SH 71/Ben White Boulevard, will be closed nightly on Friday, March 6, from 11 p.m. to 9 a.m., and Saturday, March 7, from 11 p.m. to 10 a.m., for work on the elevated managed lanes. Detours will be in place (see map below for more details):
