The Port Authority, under its Bayonne Bridge Navigational Clearance Program (BBNCP), is proposing to reconstruct the arch span roadway and approaches of the Bayonne Bridge, raising the roadway to a higher elevation, thereby increasing the air draft. The existing arch will be used to support the main span roadway as required to allow the roadway to pass through the arch at a higher elevation. The navigational clearance at the center of the arch will be increased from 151-ft to 215-ft above mean high water (MHW). The width of the main span roadway is limited to 70-ft due to the structure of the arch. The NJ approach and NY approach substructure will be replaced or reinforced and seismically retrofitted to support the new approach superstructure. The NJ viaduct will be replaced. B. Thayer Associates is providing Engineering Support services for the preparation of the Design Development Package and Design/Build contract documents for implementation of the "Raise Roadway" alternative; and providing engineering support services as needed through the final design and construction stages.
