North Street Bridge Over West Brothers Brook

Project Background

North Street Bridge over West Brothers Brook (bridge number 056-047) is a single-span reinforced concrete slab bridge supported by stone masonry abutments, which was originally built in 1909, and rebuilt in 1950 with the last major maintenance occurring in both 2010 and 2022.  The structure is located on a major arterial road that is highly traveled by commuters and is approximately 0.9 miles away from the nearest school. Scheduled inspections of the bridge have taken place every four years as required with incidental repairs following each inspection as needed. The last inspection took place on March 7, 2022, resulting in the bridge being in critical condition. Immediately after that inspection emergency repairs took place and the consultant selection process commenced for the proposed design. Within the last four years, due to major storm events, undermining of the footings has occurred, from scouring, and most recently an abutment was displaced by the heavy flow and velocity of water with the washing out of materials behind the abutment. Emergency temporary repairs as noted above were performed for safety. It is evident that this structure is in need of complete replacement.

Timing and Next Steps 

The project is currently in the preliminary design phase. The cost of this project will be covered under the Local Transportation Capital Improvement Program (LOTCIP) with funds reimbursable to the Town at 100 percent for construction and construction inspection. 

This proposed project is in the Selectman's Budget for Fiscal Year 2023/24 under the Capital Improvement Plan. Project funding requires approval from the BET and RTM during the budget review process. The estimated project cost is $3,000,000, which is reimbursed by the LOTCIP grant.
