San Antonio Area Freeway System
PROJECT INFO: Loop 1604 from Bandera to Culebra

This page last updated December 4, 2016


Project locationThis project is complete.

Loop 1604 from Bandera Rd. to Culebra Rd.

Status: Complete

This project will upgrade Loop 1604 at this location from a four-lane divided highway to a four-lane, toll-free expressway.  This includes adding
overpasses at Braun Rd., New Gilbeau Rd., and Shaenfield Rd., continuous access roads, and entrance and exit ramps.  There was an option for TxDOT to add the interchange at SH 151 to this project which was executed.  More info on that project here.

How this project will help
Staggering ongoing growth in this area of San Antonio necessitates upgrading this roadway.  Although the superstreet and associated improvements helped significantly reduce congestion, this area still experiences frequent backups due to the signalized intersections, especially at Braun.  The new expressway lanes with overpasses at the previously signalized intersections will provide for continuous free-flowing traffic through the corridor. 
The four expressway lanes are anticipated to handle the projected traffic in this corridor for the next 20 years.

Construction began in March 2014 and is on-track to be complete by mid-summer 2016.  The new southbound lanes opened on April 23rd.  The northbound lanes opened May 12th.  Click here for the latest status report on this project.
