The Hoover Dam Bypass
The Hoover Dam Bypass joins one of the most famous civil engineering landmarks in the world. Set in such close proximity to this national treasure, the Colorado River crossing has its own story to tell: it is the highest and longest concrete arch bridge in the Western Hemisphere and features the world’s tallest precast concrete columns. Such an engineering challenge was undertaken with solemn obligation—to design a bridge that would complement its neighbor and proudly take its own place as a structure of immeasurable grandeur.
The 2,000-foot-long bridge located 1,500 feet downstream of Hoover Dam is the dramatic centerpiece of the Hoover Dam Bypass Project, which includes new approaches on both sides of the river and six other bridges. Other significant project features include rock cuts and fills exceeding 100 feet in height, wildlife underpasses, and pedestrian access and accommodations. The need for economy, speed of construction in a challenging canyon environment, and aesthetics, resulted in the first steel-concrete hybrid arch bridge in the United States. The design team presented a bridge that complements the concrete arch-gravity dam with a high-performance concrete arch while limiting load demands with a modern steel composite superstructure. The bridge was also designed to meet the challenge of towering construction 890 feet above the river with rim-only access.
