US-80 TEXAS STREET BRIDGE OVER RED RIVER
The US-80 Texas Street Bridge, built in 1934, is an historic bridge which carries US-80 over the Red River. The bridge is used primarily for local traffic traveling between the cities of Shreveport and Bossier City in Louisiana. The bridge consists of 45 spans with a total length of 2,895 ft. The approach spans consist of reinforced concrete T-beam girders and steel deck trusses. The main span is composed of three steel truss spans.
SDR’s scope of work included in-depth inspection of all structural elements; LRFR load rating analysis; identification of structurally-deficient elements, and design of structural strengthening. A three-dimensional finite element analysis was utilized to determine the internal forces on all structure members. SDR also provided construction support.
