SH 46 from I-35 to I-10

Project background

The Texas Department of Transportation San Antonio District is proposing to improve SH 46 from I-35 to I-10 and I-35 from South Walnut Avenue to FM 306 in Comal and Guadalupe counties, Texas. TxDOT has been working collaboratively with Comal County, the City of New Braunfels, Guadalupe County and the City of Seguin to help identify corridor issues and concerns.

Project description

Improvements along SH 46 are needed to meet current and future traffic volumes and regional population growth. The purpose of the project is to reduce congestion, improve mobility and increase safety along SH 46. TxDOT is proposing to expand SH 46 with operational and corridor improvements including additional lanes, overpasses and intersection improvements. The proposed expansion also includes limited ramp reconstruction along I-35.
