State Highway 45 is a freeway loop around Austin, Texas, that exists in two open segments. The official designation of SH 45 is such to form a complete loop around Austin, a distance of roughly 80 miles (130 km).
One segment is in southwest Austin and runs southeast from
The other segment is a toll road that forms a backwards C-shape along the boundary of Travis and Williamson County before bending down along the eastern edge of the Austin metropolitan area where it shares its route with SH-130.

SH 45 North
SH 45 North is an approximately 13-mile (21 km) segment in the north Austin metropolitan area. The freeway's western terminus is at US 183 northwest of Austin in
The
SH 45 Southeast
SH 45 Southeast is a 7.4-mile (11.9 km), tolled segment southeast of Austin, near
Originally planned as part of the 2002 CTTP, SH 45 Southeast became the subject of controversy, delaying development and necessitating it as a separate project. In 2006, an environmental advocacy group filed a lawsuit in an effort to move the alignment further south. By the summer of the same year, the Federal Highway Administration approved a new environmental impact study affirming the existing alignment, and a federal judge dismissed the case, clearing the way for construction, which began in Summer 2007. SH 45 Southeast was opened to traffic on May 7, 2009.
SH 45 Southwest
SH 45 Southwest is a 3.6-mile (5.8 km) tollway link between the southern terminus of
The highway will still require a segment between FM 1626 and I-35 to connect to the other tolled segments of SH 45. This section, SH 45 South, is already included in the Capital Area Metropolitan Planning Organization (CAMPO) 2040 Plan for study.[6] This missing link was one source of controversy surrounding the alignment of SH 45 Southeast. Opponents claimed the proximity of the southwestern and southeastern sections would create more pressure to connect the two and that, if built, the link would encourage development on or near environmentally sensitive land. Planning for the western portions of SH 45 to form a complete loop is still very early, although a proposal for possible route has already been offered by the City of Lakeway.[7][8]
History
SH 45A was a spur designated on September 14, 1926, from Coldspring west to New Waverly.[13] On March 19, 1930, this spur was renumbered as SH 150.
On February 11, 2021, icy conditions caused a 26 vehicle pile-up. This incident occurred near the overpass with
