TX-151, San Antonio, TX, USA

State Highway 151, or SH 151, also known as the Raymond E. Stotzer Jr. Freeway is a 10.7-mile (17.2 km) state highway in the U.S. state of Texas that runs from Loop 1604 to U.S. Highway 90 (US 90) in San Antonio. SH 151 is a limited-access freeway for its entire length with the exception of its junction with Loop 1604 at its western terminus where a traffic light controls the junction. 

The routing of the freeway was first conceived in 1983 and construction was conducted in phases through the 1980s and 1990s until completion in 2004. The freeway provides access to the western part of San Antonio, the SeaWorld San Antonio theme park, Chase, Northwest Vista College, and the future site of a Microsoft data center.

About The Freeway

The first SH 151 was designated on March 19, 1930, from Mason to Menard as a renumbering of SH 29A. On February 11, 1938, SH 151 extended west to Eldorado. On April 29, 1942, the section of SH 151 west of Menard was cancelled and renamed FM 43, with the section west of the roadway north of the San Saba River 6.5 miles (10.5 km) west of US 83 cancelled. On March 17, 1948, FM 43 became part of SH 151, extending it to Eldorado. On August 22, 1951, SH 151 was cancelled and transferred to SH 29 which was extended. 

The freeway was built in phases with the frontage roads constructed first followed by the main lanes. The overpasses for Wiseman Boulevard, Westover Hills Boulevard and Military Drive between I-410 and Loop 1604 were completed over the main lanes of SH 151 in 1987. In 1988, the I-410 overpasses over the SH 151 frontage roads were completed, as was the interchange with US 90 at the eastern terminus. Also completed in 1988 were the frontage road bridges over Leon and Slick Ranch Creek, which enabled traffic to travel the entire corridor from Loop 1604 to US 90 by way of the frontage roads. The main lane overpasses at FM 1957 (Potranco Road) and Ingram Road were completed in 1997. The overpasses at Pinn Road and Enrique M. Barrera Parkway were completed in 1998, and completed at Callaghan Road in 2000. Construction of the freeway was completed in 2004.
