This parallel crossing spans from Virginia Beach to the Maryland Peninsula and consists of more than 12 miles of new low-level precast modular spans supported on 54" and 66" diameter precast pipe piles and precast caps. The project included self-erecting high-level structural steel plate girder spans in the north channel (3,100' long) and at Fisherman's Inlet (460' long) with cast-in-place decks. The project also included tunnel approach widening and placement of significant armoring stone on four portal islands, along with a new 15 KV feeder, a fiber-optic system, telephone and traffic control devices, and lighting.
To accommodate the fast-paced schedule and lack of competitive local pricing, the project team established a precasting facility near the new bridge to produce all precast concrete structural elements. This type of accelerated bridge construction (ABC) method included, precast bent caps and 150-ton modular deck units. Our fleet of 23 marine construction vessels including two 300-ton Jack-Up barges and two 300-ton Ringer Crane Barges were essential for the on-time completion of this project. The project team coordinated with the busy Naval Port Facility at Norfolk and Little Creek. When conditions prevented the normal delivery of the modules, the project team developed a unique approach of utilizing heavy lift trailers to deliver and off-load the 150-ton modules.
