It was built in 1939-1940 by Cage Brothers & L.A. Turner to a Texas Highway Department design.","why_significant":"The bridge embodies the defining characteristics of a Texas Highway Department truss bridge and is significant under Criterion C in engineering at the state level. It is a custom design with a top chord curved like a suspension bridge cable. It is one of only seven surviving continuous through truss bridges in Texas and one of five built before World War II.","narrative":"Carrying US 190 across the Colorado River where Lampasas and San Saba counties meet, this bridge is a 1,294-foot steel structure completed in 1940. It has a 600-foot three-span continuous Warren truss with three continuous I-beam approach units on the west end, all resting on reinforced concrete piers. Texas Highway Department engineers designed it specially after a July 1938 flood damaged the earlier Red Bluff Bridge. The top chord curves between high points over the piers, resembling a suspension bridge cable. Federal emergency relief funds paid half of the cost. Cage Brothers & L.A. Turner built it using the cantilever method, and it opened 65 days ahead of schedule. It is one of only seven continuous through truss bridges left in Texas and has seen no major alterations since construction. Its significance rests on engineering design and its representation of Texas Highway Department truss work.","period_of_significance":"1939-1940","architect_builder":"Bridge Designer: Texas Highway Department; Truss Fabricator: Virginia Bridge Company of Roanoke, Virginia; Bridge Builder: Cage Brothers & L.A.
