Loop 1604 from US 90 to FM 1957 (Potranco Road)

The Texas Department of Transportation is proposing improvements to Loop 1604 between US 90 and FM 1957 (Potranco Road) in San Antonio.

The proposed improvements are needed due to high traffic and congestion. The proposed project would expand Loop 1604 to a four-lane expressway (non-toll lanes). Proposed improvements include construction of:

  • Southbound mainlanes and frontage road
  • Entrance and exit ramps
  • Direct connector (flyover) from southbound Loop 1604 to eastbound US 90
  • Grade separations at US 90, Marbach Road and Dove Canyon

The proposed $80 million project is designed to improve safety and mobility for the FM 1957 corridor.
