Capital Express South

Overview

The Capital Express South project proposes to add two non-tolled managed lanes in each direction along I-35 from SH 71/Ben White Boulevard to SH 45 Southeast. Managed lanes are proposed in high-congestion areas where right of way is limited. These lanes are designed to provide a less congested route than adjacent general-purpose lanes during peak periods for qualifying vehicles. Managed lanes control access by placing restrictions on use. The project also includes additional safety and mobility improvements.
