I-35 Waco Project 3A1 - Troy

Project ID (CSJ)

  • 0015-04-067


Project 3A1 is widening I-35 from 4 lanes to 6 lanes for approximately 6.4 miles from Loop 363 in Temple to North Troy City limits in Bell County.


Increased truck traffic along the I-35 corridor coupled with regional population growth in Texas has created travel demand that exceeds its current capacity. The existing I-35 facility through Central Texas is an essential element of the local and regional transportation system.


The purpose of the project is to meet local and regional travel demands by increasing capacity; upgrading the transportation infrastructure to meet current FHWA and TxDOT design standards for interstates, bridges, and frontage roads; thereby improving the safety of travelers along I-35.

End Result

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

  • Widening approximately 6.4 miles of I-35 from four lanes to six lanes (three lanes in each direction).
  • Upgrading on and off ramps.
  • Converting frontage roads to one-way
  • New direct connectors, u-turns and traffic signals
  • Converting Main St./FM935 from an underpass to an overpass


  • Construction Cost Estimate: $123.6 million


  • Construction complete
