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.
David Goodyear, PE, SE, NAE
David’s engineering practice has focused on bridge and heavy foundation design and construction engineering, particularly large cable- stayed and arch bridge river crossings. David served TY Lin International as a Senior Vice President. He was the Chief Engineer of Bridge Engineering for the North American Operation, leading TY Lin offices for major bridge, cable-stayed and concrete segmental design work and construction engineering. David was Founder and President of DGES Consulting Engineers, Inc, Olympia, Washington. David founded DGES in 1988 after serving as Senior Engineer and Principal at Arvid Grant and Associates. His practice, which focused on segmental and cable-stayed bridge engineering and construction services, was sold to TY Lin International in 1995.
David also has a variety of experience with code development, general structural design, engineering contract development and contract administration experience for Owners and contractors in the bridge and heavy civil construction field. David’s experience with bridge and waterfront structures has included a significant amount of heavy foundation design, including the design of cofferdams, caissons and large capacity piles. His practice has included design of piling and drilled shaft foundations for high seismic loads, as well as construction surveillance of pile installations.
