I-35 Waco Project 4C - Waco South

Project ID (CSJ)

  • 0015-01-246


Project 4C Waco South will widen I-35 from six lanes to eight lanes for approximately 3.285 miles through Waco, from South Loop 340 to 12th Street.


The I-35 corridor is an important route for intrastate, interstate, and international commerce, resulting in heavy use by commuters, freight trucks, and business travelers. Increased truck traffic coupled with regional population growth in Texas has created travel demand along I-35 that exceeds its current capacity. The existing I-35 facility through Central Texas is an essential element of the local and regional transportation system. Within the project limits, I-35 serves multiple purposes. It functions as an interstate providing north-south regional access, but also represents a key component of the roadway network for local trips within and between Waco, Hillsboro, Salado and beyond.


New acccess road lanes will provide additional access accross the Brazos River, decreasing congestion on the mainlanes and providing a safe route across the river in the event of crashes or other conditions causing a blockage of the mainlanes.

End Result

This project will address congestion while improving safety at this I-35 location by:

  • Widening 3.285 miles of I-35 from six lanes to eight lanes (four lanes in each direction).
  • Updated access roads and access points from local streets, on- and off-ramp configuration and placement, new bridges, and improved traffic control.


  • Construction Cost Estimate: $200 million


  • Construction Start Date: to be determined
