East Bay Avenue Over Double Creek

East Bay Avenue crosses over Double Creek providing access to the Jersey shore community of Barnegat, including area beaches, marinas, local businesses, and residences. With the existing weight-restricted nine span timber structure being classified as functionally obsolete, Ocean County, New Jersey, contracted with NV5 to provide preliminary and final design, environmental/permitting, surveying/ROW, and construction support services for the replacement of the existing structure.

Project design constraints included tidal and freshwater wetlands, navigable tidal waters, shellfish habitat, endangered species, an adjacent Federal Wildlife Refuge, constrained ROW, overhead and underground utilities, and existing road and bridge geometry limitations. The proposed structure consists of a three span continuous bridge of steel composite construction founded on reinforced concrete abutments and pier caps supported by concrete filled steel pipe piles.

Design services included surveying/mapping, alternatives analysis, alignment studies, traffic analysis, H&H studies, as well as the preparation of final plans, specifications and estimate in accordance with AASHTO and NJDOT Design Manuals and Specifications as modified by Ocean County. The project also included environmental studies & permitting (CAFRA, Waterfront Development, Fresh Water Wetlands, Coastal/Tidal Wetlands, ACOE, and Ocean County Soil Conservation District), maintenance and protection of traffic, and preparation of ROW documents. The project required coordination with the US Coast Guard and installation of a timber fender system and navigation lighting. Extensive coordination was also required with the above- and below-ground utilities during design development. The structure will support a 6” wastewater force main off the north fascia stringer while the existing 4” gas main will be directionally drilled below the proposed structure.
