East Cottage St and Norfolk Ave Bridge Replacement

Timeline: Winter 2021 – Summer 2023
The East Cottage Street and Norfolk Avenue bridges, between the Uphams Corner and Newmarket stations, carry the Fairmount Line through Roxbury and Dorchester. We’re replacing the bridges, both built in 1906, with updated steel infrastructures to improve safety and reliability.
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.
Project Features and Benefits
- Replace existing bridges to extend service life by 75 years
- Strengthen the support structures to increase load capacity
- Remove speed restrictions to reduce service delays
- Repaint community mural on East Cottage Street
What to Expect During This Work

To minimize service impacts, we will accelerate construction and limit rail service disruptions and road closures to weekends.

Pedestrians
We will maintain access to at least one of the sidewalks at a time under the bridge. If pedestrian traffic is impacted due to the road closures, we will post detour signage.
Parking
Residents will not be able to park under East Cottage Street or Norfolk Avenue bridges throughout construction.
