Loop 345 is an 8.24-mile (13.261 km) loop route through the city of San Antonio in the U.S. state of Texas. It follows a former route of U.S. Highway 87 (US 87), which it now separates from, about 4.5-mile (7.242 km) north of Balcones Heights on the outskirts of San Antonio, on the way into that city. The road is a major arterial for San Antonio and a main route into Balcones Heights, providing access to the United Services Automobile Association (USAA) headquarters as well as to the South Texas Medical Center.

History[edit]

Loop 345 follows the original routing of US 87 on the northwest side of San Antonio.[1] The road was designated as US 87 along this stretch in 1935. It is named Fredericksburg Road because this road out of San Antonio was, at that time, the main route to Fredericksburg, about 65-mile (104.607 km) north of San Antonio.[2] In 1962, when US 87 was rerouted onto a freeway to the east of this section of the Fredericksburg Road, the route was signed as Business US 87 until 1992, when it was re-designated as Loop 345.[1]

Route description[edit]

Loop 345 follows Fredericksburg Road from Interstate 10 northwest of Downtown San Antonio towards the northwest, passing through Balcones Heights and joining Interstate 10 again near the USAA headquarters, roughly paralleling Interstate 10 the entire way. The road passes through Balcones Heights, providing access to Crossroads Mall before a junction with Interstate 410. After passing I-410, Loop 345 passes by the South Texas Medical Center which includes the University of Texas Health Science Center, University Hospital and the Children's Cancer Research Institute. It then passes to the south of the USAA financial services headquarters before rejoining Interstate 10 near Huebner Road.[3]

Junction list[edit]

The entire route is in Bexar County.
