The meaning of «texas state highway 45»

State Highway 45 is a highway 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 Ranch to Market Road 1826 to Farm to Market Road 1626 and intersects the southern terminus of Loop 1 (Mopac Expressway). Between RM 1826 and Loop 1, the roadway is a divided, four-lane facility with a wide median intended to accommodate a future freeway, after which the current lanes would serve as frontage roads. Between Loop 1 and FM 1626, the roadway becomes a tolled freeway.

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.

Before the 2002 Central Texas Turnpike Project (CTTP), SH 45 existed only as a short section of four-lane, divided highway in southwest Austin. The CTTP added a toll road that runs east from US 183 near Cedar Park, crosses I-35, bi-secting the La Frontera development, and meets SH 130 near Pflugerville. South of this interchange, SH 45 is co-signed with SH 130 to US 183 just south of Austin-Bergstrom International Airport. SH 45 then loops westward rejoining I-35 north of Buda.

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 Cedar Park. For a distance, RM 620 travels concurrently with the frontage roads also designated as State Highway 45 (non-tolled). Heading east, the freeway intercepts Loop 1's northern terminus, bisects La Frontera and crosses I-35. This particular segment ends at SH 130 near Pflugerville, but the SH 45 designation continues southward along SH 130.

The Texas Department of Transportation had originally planned to complete construction of the entire 2002 CTTP in September 2007 but opened some sections of SH 45 North as early as October 31, 2006.

SH 45 Southeast is a 7.4-mile (11.9 km), tolled segment southeast of Austin, near Creedmoor, Texas. Roughly paralleling Farm to Market Road 1327, it is a four-lane, controlled-access facility that links SH 130 and US 183 to Interstate 35 north of Buda, Texas. It completes the SH 45 eastern bypass loop around the Austin metropolitan area.

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.
