State Highway 71 Toll Lanes – Texas Department of Transportation

Austin Texas

TxDOT selected a team from LAN and McCarthy Building Companies in June 2014 to develop, design, and construct the SH 71 Express Toll Lanes through a design-build agreement. SH 71 is a major thoroughfare for commuters traveling from downtown Austin to the Austin Bergstrom International Airport and for Central Texas motorists traveling to Houston. LAN served as the Lead Engineering Firm for the project, which provided upgrades to improve mobility in the area and meet future travel demands. This project is the fastest alternative-delivery procurement that TxDOT has ever managed.

The $149 million project, completed in 2016 on an accelerated design and construction schedule, provides a much needed relief to Austin commuters.

LAN served as the lead designer responsible for environmental compliance, utility coordination and relocation, survey, geotechnical services, design and construction support.
