Visualization fly over

TxDOT is improving mobility for San Antonio drivers with the US 90 Expansion project in West Bexar County. This transformative project is a significant investment in transportation infrastructure designed to increase connectivity, reduce congestion, and enhance safety within the region. The 7.6-mile project involves widening the existing four-lane divided roadway to a six-lane expressway from I-410 to SH 211, as well as improving connections at key interchanges and cross streets.

The Texas Transportation Commission has designated the US 90 Expansion project as part of the statewide Texas Clear Lanes initiative, organized to address the most congested areas in the state.

Improvements

The following project elements are included:

  • Expanding US 90 from a four-lane divided highway to a six-lane expressway with three mainlanes in each direction.
  • Widening the roadway footprint to accommodate continuous two-to-three lane frontage roads in each direction.
  • Constructing a two-lane flyover ramp connecting westbound US 90 to northbound Loop 1604.
  • Improving intersections at major north/south cross streets, including Loop 1604, Montgomery Road, and Hunt Lane.
  • Adding a westbound-to-eastbound turnaround at the US 90/SH 211 intersection; and eastbound-to-westbound turnaround bridges along US 90 at Loop 1604 and Montgomery Road.
  • Adding a roundabout on the south side of US 90 at Ray Ellison Boulevard and Hunt Lane/Crooked Trail.
  • Building sidewalks to enhance bicycle and pedestrian access.

Exisiting and future conditions

Existing US 90 typial section showing the current configuration of US 90 between Loop 1604 and Hunt Lane. The image depicts two-lane frontage roads for eastbound and westbound US 90, and 3 mainlanes in each direction, all across a 320' width. There is a sidewalk along the eastbound US 90 frontage road.
Existing US 90 proposed typical section showing the proposed configuration of US 90 between Loop 1604 and Hunt Lane. The image depicts the project adding one lane to existing two-lane frontage roads and a new sidewalk for westbound US 90, and 1 lane added to the existing mainlanes in each direction. The usual width for the section is 590' and includes a wider inside shoulder on the mainlanes.

Benefits

Once complete, the improvements will:

  • Reduce congestion
  • Improve connectivity
  • Enhance safety
  • Reduce future commute times by as much as 90 percent by 2045. For more information, see study estimates here.
