Project History

As a result of growth and development, drivers are using local roads, such as Manchaca Road, Slaughter Lane and Brodie Lane as commuter corridors and to access MoPac and downtown Austin. These local roads have become increasingly congested, with signalized intersections exacerbating the traffic problem. Some neighbors also express concerns about cut-through traffic and the inability to safely exit their neighborhoods.

The Texas Department of Transportation (TxDOT) launched a new environmental study in June 2013 to study a possible solution for improving mobility in the rapidly growing area of northern Hays and southern Travis counties. This study identified the construction of SH 45SW, a new four-lane toll road on existing state-owned right-of-way from MoPac to FM 1626, as the recommended action. 

During that study, a comprehensive document, called an Environmental Impact Statement (EIS), was developed to fully evaluate and disclose the potential impacts of the project. In July 2014, this document was presented to the public for review and comment. The document was later submitted for state review and an environmental decision on the project. On March 5, 2015, the Texas Department of Transportation issued a Record of Decision (ROD) which allowed the SH 45SW project to proceed to final design and construction, with specific commitments to protect the environment during its construction and operation. 

In July 2016, the contract for SH 45SW construction was provisionally awarded to McCarthy Building Companies followed by an issuance of Notice to Proceed in October 2016. Construction on SH 45SW officially commenced in November 2016 and was opened to traffic on June 1, 2019.
