GCW prepared preliminary and final design of five pedestrian overpass structures located along two trails within the City of Las Vegas: the Las Vegas Wash Trail and the Lone Mountain Trail. GCW’s work involved the engineering and design of all approaches and bridges for the elevated crossings that occur at Lamb Boulevard, Charleston Boulevard, Cheyenne Avenue, Lake Mead Boulevard, and the Cultural Corridor crossing of Las Vegas Boulevard. Work involved design of concrete abutments and bridge piers for a combination of cast-in-place concrete and prefabricated steel superstructures. Main spans over roadways were specified as prefabricated steel trusses, while approach spans were designed as CIP concrete box girders. Approach ramps are designed as earth-filled concrete retaining wall ramps. Work includes preparing engineering plans, specifications, and cost estimates for constructing the pedestrian bridges. The work includes hydraulic analysis for crossings of flood control channels. Engineering services included survey, right-of-way, easement acquisition documents, utility research, geotechnical investigations, lighting analysis and design, PS&E preparation, aesthetic design alternatives for future enhancements, and bidding assistance. An alignment study and design workshop was also provided. The Cultural Corridor and Lone Mountain Trail Pedestrian Bridges were recognized by APWA as Project of the Year in the structures category in 2012.
