It was built in 1915.","why_significant":"It is an excellent, virtually unaltered example of an early reinforced concrete closed-spandrel arch bridge, one of a small number surviving in Texas. It was built as part of the first federal aid highway project in Texas, which improved the Austin-San Antonio Post Road. It is nominated at the state level under Criterion A for transportation and Criterion C for engineering.","narrative":"Bridge No. 44, now called the Bunton Branch Bridge, is a small concrete arch carrying County Road 210 over an intermittent creek just north of Kyle, Hays County, Texas. Built in 1915, it has a single 40-foot semi-circular closed-spandrel arch on concrete abutments, solid parapets, and skewed wing walls, with the date and bridge number stamped on the railing. It carries one lane of traffic on an 18-foot asphalt roadway. The bridge was part of the first federal aid highway project in Texas, which upgraded the old Austin-San Antonio Post Road, later State Highway 2. Of roughly 35 bridges on that project, it is the only known reinforced concrete arch, a design probably chosen because stone in the streambed allowed a more economical foundation. It is valued as a rare, largely unaltered early example of this bridge type, and for its link to the post road and early federal road funding in Texas.","period_of_significance":"1915-1932","architect_builder":"J.N.
