I-45 South Madison County Projects (Segments 4 and 5)

Segment 4 and Segment 5

Purpose

The I-45 South Madison County Projects includes Segments 4 and 5 and part of the larger I-45 Corridor Program, which has been created to enhance safety and improve mobility along 90.4 miles of I-45 through Walker, Madison, Leon, and Freestone counties. It serves as the main connection between Dallas and Houston. I-45 is also a major freight corridor and hurricane evacuation route.

The I-45 South Madison County Projects (Segments 4 and 5) proposes to update the roadway to current design standards, increase its capacity to accommodate future traffic volumes, and improve access for local travelers.

Proposed improvements

  • Adding one mainlane in each direction.
  • Updating the roadway to current interstate design standards
  • Converting existing two-way frontage roads north of US 190/SH 21 to one-way frontage roads
  • Providing a new two-way frontage road between FM 2989 and Spur 67
  • Replacing bridges and increasing vertical clearance to 19-feet.
  • Improving traffic flow at interchanges, including the use of innovative intersections
  • Providing shared-use paths (wide sidewalks) for pedestrian and bicycle use, where appropriate
