NORTHAMPTON- BRIDGE REPLACEMENT, N-19-029, RIVER ROAD OVER THE MILL RIVER
The proposed River Road over the Mill River bridge replacement project consists of replacing the existing two-span structurally-deficient concrete-arch bridge with a new single span prestressed concrete beam bridge on the same general alignment. The work will extend approximately 300 feet south of the bridge and 200 feet north of the bridge. This approach roadway work will consist of reconstruction of the existing pavement, minor vertical and horizontal alignment improvements, and safety improvements such as proper guardrail transition to the bridge, pavement markings, and signage. The project will be constructed in one phase using a complete roadway closure with detour around the project site.
