The 9,559-foot long Homer Hadley Bridge is part of the westbound I-90 bridge connecting Seattle and Bellevue. General Construction replaced the expansion joints that were cracked and deteriorating. This was a two-part process with the small joints being removed and replaced in May 2009 and the large joints being removed and replaced in July 2009.
The E2 foundation, on the east end of the project, consists of a composite steel and concrete footing founded on 16 cast-in-steel shell piles driven 300 ft into the San Francisco Bay mud. The T1 foundation at the west end of the project is the foundation for the main suspension tower of the self anchored suspension bridge. It consists of 13 cast-in-place drilled hole piles which extend approximately 200 ft into the Alameda rock formation.
$1.2 billion Skyway Bridge project included the construction of a mile and a half of side-by-side viaduct bridge structures in San Francisco Bay. The contract was the first of several to replace the existing east span of the San Francisco Oakland Bay Bridge. Each structure is designed to carry five lanes of vehicular traffic and has two breakdown lanes.
More than 115,000 vehicles cross the aging SR520 floating bridge between Seattle and Bellevue on a daily basis, and it was imperative that the Washington State Department of Transportation (WSDOT) provide commuters a new, safer and more modern bridge to withstand potential seismic activity and severe weather. Kiewit-General, a Joint Venture (K-G) was selected as the best value contractor to build the pontoons that will support the new roadway superstructure.
General Construction Company, part of the Tacoma Narrows Constructors joint venture, was responsible for construction of the two foundation caissons that support the suspension towers of the new Tacoma Narrows Bridge. Each finished caisson is 80 feet wide, 130 feet long and up to 234 feet tall and located in water depths of about 140 feet, where they penetrate over 60 feet into the sea floor and extend to the surface above the highest tide elevations.
The project consisted of driving six 10 ft diameter piles down into bedrock. Pile lengths were 136 ft to 200 ft. The piles were drilled out and socketed into bedrock up to 30 ft. Rebar cages were installed full depth and the pile was filled with concrete. Pier caps were constructed on top of the pile. Twelve 7 ft. square precast box girder sections, ranging in length from 84 ft to 180 ft, were fabricated and set in pairs on top of the caps.
The new Benicia-Martinez Bridge is a four frame, 2,266 meter long by 25 meter wide cast-in-place, post tensioned, segmental concrete bridge spanning the Carquinez Strait. The superstructure is supported by seventeen pile-supported foundations, twelve of which are located in water. The bridge carries five lanes of northbound Interstate 680 traffic and has the potential for a future BART light rail lane.
