22 | ASPIRE , Fall 2007 The Monroe Street Bridge in downtown Spokane, Wash., has provided a critical north-south traffic link within the city since 1911. At almost a century old, the bridge was near the end of its useful life when a rehabilitation project was launched in 2001. The project posed a number of significant challenges due to historic preservation requirements, environmental concerns, and the functional aspects of replacing a bridge that spans a 136-ft-deep river gorge. The project designers used a combination of precast and cast-in-place concrete components to meet these requirements. The existing design featured a three-span concrete arch structure with reinforced concrete approaches. The total length is 896 ft with a main river span of 281 ft and two side spans of 120 ft. Four original pavilions over the sidewalks at the main piers projected into the travel lanes and had been damaged repeatedly by vehicle impacts. profile Monroe Street Bridge / SPoKAnE, wASHInGton EnginEEr: david Evans and Associates, Inc., Salem, ore., and Spokane, wash.
