Highway / Express Toll Lanes


The US 183 South / Bergstrom Expressway project will be an 8-mile highway and express toll facility in Austin, Texas, connecting US 290 and SH 71. The project will expand the capacity of existing US 183, a north-south arterial serving more than 60,000 vehicles per day as an alternative to the heavily congested I-35 to the west. US 183 provides a route for commuters from several cities to Downtown Austin and is one of three highways providing access to Austin-Bergstrom International Airport. In its current configuration, with numerous at-grade intersections, US 183's mobility and operational benefits are limited and could be maximized by a more complete roadway network.

The project consists of six tolled main lanes in the median of US 183, four to six upgraded general purpose lanes, five grade-separated interchanges, four new bridges, two new tolled direct connect flyover ramps at SH 71, and the installation of intelligent traffic management systems. The project also includes bike lanes, pedestrian sidewalks, and shared-use paths. The project will be constructed in two phases. Phase 1 between US 290 and Bolm Road is expected to be completed in late 2019, and Phase 2 continuing from Bolm Road to SH 71 about one year later.

Innovations The project incorporates Context Sensitive Solutions to bring aesthetic enhancements to the corridor. These features resulted from a 16-month planning and public input process conducted by CTRMA and the Texas Department of Transportation. They include enhanced landscape such as neighborhood specific tree species and native, drought resistant plants that reduce water consumption and help control soil erosion. Community connections are planned through trailheads, roadway crossings, and intersection improvements for pedestrians. Regional identity will be emphasized in bridge and retaining wall design. Large oak trees will be preserved throughout the project limits by applying Best Management Practices.
