The scope of this study is a 3-mile section of State Highway (SH) 146 from Red Bluff to south of the Galveston/Harris county line.

Current Conditions

Currently, SH 146 has many different cross sections, but typically it is a multi-lane, paved highway with a center turn lane or grassy median.

Proposed Improvements

The proposed project would consist of the following:

  • Widen and restructure the existing facility to a six- to 12-lane freeway
  • Add grade separations at major intersections
  • Add access roads in selected locations
  • Add express lanes over Clear Creek


This study is a partnership between TxDOT and the Federal Highway Administration.
