The Hood Canal Bridge is the main economic transportation link between the Puget Sound and the Olympic Peninsula. This unique project called for the construction of new floating concrete pontoon roadway sections as well as new bridge approaches. The floating pontoons are being constructed in a sheet pile graving dock. A total of 50,000 cubic yards of structural concrete will be placed for this job. A temporary work trestle was constructed on the south side of the canal to facilitate the removal and replacement of the structural steel approach span.
These twin precast segmental bridges will accommodate five lanes of traffic in each direction and a bike path on one side. Each bridge is 87 feet wide by 6000 feet long. KECo performed a complete estimate for the $1.2 billion project. KECo estimated the substructure, balanced cantilever and superstructure erection. We also estimated the setup of the precast yard and precasting of the 800-ton segments.
Estimating Services provided a complete estimate of schedule for the I-95 Sound Walls.
