Removal of the Northumberland Street Bridge Over Morristown Bay

The project consists of the complete removal of the existing bridge and causeway that carries Northumberland Street over Morristown Bay. The existing bridge consists of multiple steel girders and an open steel grate deck system supported on concrete abutments on steel H-piles. There is approximately 250 linear feet of causeway that extends from the shoreline to the existing abutments that will be completely removed. The existing bridge supports both an 8” water line and a 6” vacuum sewer line that will be relocated off of the bridge to under the bay. The water line will be directionally drilled under the bay and tied into the existing system on both approaches. The sewer line will be converted to a vacuum system to a force main on the west side of the bay and then directionally drilled. The work associated with the sewer line includes installation of 1100 linear feet of vacuum line, installation of 1100 linear feet of force main and the installation of a new vacuum/pump station along Bay Street. Approximately 250 linear feet of full depth approach reconstruction includes the replacement of sidewalks, construction of a parking area and the construction of green space areas at the shorelines. All traffic will be maintained off site during construction.
