A the time it began, the State Highway 45 - Section 8 Central Texas Turnpike in Austin was Austin Bridge & Road's single largest project in its history. The TxDOT highway project included building a five-level interchange, 13 bridges, 177 bridge spans, as well as a 4.3-mile-long-tollway for the Texas Turnpike Authority. Austin Bridge & Road completed the project ahead of schedule, and was awarded the 2008 AGC Aon Build America Award.
