Dedham East Street Bridge Replacement
Building a Better T
As part of our $9.6 billion, 5-year capital investment plan, we're renovating stations, modernizing fare collection systems, upgrading services for our buses, subways, and ferries, and improving the accessibility of the entire system.
We’re replacing the bridge that carries the Franklin Line over East Street between the Endicott and Dedham Corporate Center stations.
The current East Street Bridge, which was built in 1904, has a substandard height of 12' 3", which has led to many truck collisions. Over the last 12 months, the East Street bridge has been struck 10 times by over height vehicles. The MBTA continues to partner with the Town of Dedham to enforce the existing truck exclusion on East Street.
To ensure the safety of MBTA riders and those who travel below the bridge, we will replace the current bridge to comply with bridge height standards and protect it from future collision damage.
- Design contract awarded: October 2020
- Status: Final design
- Budget: $18 million
- Projected completion: Late 2025
To reduce service disruptions and inconveniences to neighbors, we'll complete work in phases. Construction is anticipated to begin in Spring 2024.
Service Impacts
Workers on the East Street Bridge Replacement Project will use accelerated bridge construction (ABC) techniques. They will construct the new bridge superstructure adjacent to the current bridge and move it into place over a single scheduled weekend to minimize prolonged East Street traffic closures and construction impacts to MBTA operations, traffic, and neighbors.
- Endicott Station will remain open throughout the project.
- We will close the track around the bridge during some weekends to complete construction. This will impact Franklin Line Commuter Rail Service. Bus shuttles will replace train service during these weekends.
- We will define detour routes when the design phase is complete, and will publicize them once they're approved. We’ll post detour route signs during traffic closures.
- To reduce construction noise, workers will use drilled micropiles instead of driving foundation piles.
East Street drainage impacts
The roadway design will address any construction impacts on existing drainage along East Street.
