I-35 Capital Express South Project
Projects
Project overview
The project includes adding elevated managed lanes between SH 71/Ben While Boulevard and Slaughter Lane and constructing a southbound I-35 bypass lane that will allow traffic to bypass Stassney Lane and William Cannon Drive.
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 reconstruct bridges, relocate and reconstruct entrance and exit ramps, add pedestrian and bicycle paths and make additional safety and mobility improvements within the project limits.
