U.S. 380 Bridge Hydraulics

RS&H provided complete hydrologic and hydraulic analyses for the design of three separate bridge stream crossings for the widening of U.S. 380, a two-lane rural highway facility that will be upgraded to a four-lane, divided highway to improve traffic flow in central Texas. The analyses incorporated the associated impacts of all three bridges located in a FEMA-designated 100-year floodplain. Additional responsibilities included scour analyses, environmental services, bridge layouts, structural design, design and detailing of new bridges at Catlett and Denton Creek, and design of an off-system bridge over Sweetwater Creek. 

The team used HEC-RAS methodology for river stream crossings in the design, as well as performed scour analyses involving HEC-18 methodology. The Catlett Creek bridges consist of twin, three-span, Type IV prestressed beam bridges on a horizontally curved alignment supported on multicolumn bents and drilled shaft foundations. The Denton Creek Bridge consists of a six-span, Type IV prestressed beam superstructure supported on multicolumn bents and drilled shaft foundations. The Sweetwater Creek Bridge consists of a three-span, TxDOT standard slab beam bridge supported on multicolumn bents and drilled shaft foundations.
