What We're Building

SH 45SW is an innovative four-lane toll road to be constructed between MoPac and FM 1626 that will feature extensive water quality protection measures, bicycle and pedestrian accommodations and Green Mobility Challenge and context sensitive solutions.

Construction of the project commenced in November 2016 and is expected to be completed late 2019. When SH 45SW construction is complete, it will offer immediate relief to drivers in Hays and southern Travis counties and continue to provide benefit even as the population grows by redirecting commuting traffic off of local roads such as Manchaca Road, Slaughter Lane and Brodie Lane, which will better equip these arterials to serve the surrounding neighborhoods. By using SH 45SW, drivers will save 9 - 17 minutes over local routes to access Austin’s downtown core. Drivers who continue to utilize local routes to access downtown Austin will save 6 – 7 minutes minutes.

What We're Building

SH 45SW is a new four-lane divided tollway between MoPac and FM 1626. There will be two twelve-foot lanes in each direction with a ten-foot outside shoulder and a four- or five-foot inside shoulder with varying median widths. The project includes a ten-foot-wide, ADA-compliant shared use path, separated from the roadway for the entire length of the project, except over the Bear Creek Bridge. The shared use path will serve as part of the future Violet Crown Trail and will have a trailhead under the bridge structure at SH 45SW and MoPac. To protect the extensive karst features in the area, 90 percent of the project will be constructed on top of fill and will not require excavation.
