Porter Square Retaining Wall Repairs
Building a Better T
As part of our $8 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.
As part of the MBTA's Capital Investment Plan, repairs to the Porter Square retaining wall are underway. Crews will perform these much-needed repairs along the wall that runs under Somerville Avenue and along the Commuter Rail tracks. This work will help ensure the integrity of the wall and reduce future maintenance costs.
Projected completion: June 2021
Cost: $2.5 million
- Increased customer safety
- Improved accessibility for pedestrians with the installation of the new sidewalk on Somerville Ave
- Improved esthetic to the station area once the retaining wall is fully repaired
- Right-of-way (ROW) concrete repairs
- Drainage system maintenance
- Sidewalk replacement along Somerville Ave, abutting the station tracks
- Concrete repairs to the Commuter Rail platform
What to Expect During Construction
Neighbors can expect increased noise and periods of vibration from heavy equipment and machinery during construction. Contractors will be on-site to make sure noise and vibration levels are in compliance with any existing ordinances.
To allow for this work, sidewalk access has been temporarily moved parallel to the bike lane on Somerville Ave. Barriers and signage are currently in place to help direct pedestrian traffic.
Work is scheduled to occur on weekdays between 7 AM – 4 PM. We will post updates in advance here if we anticipate that nighttime or weekend work is going to take place.
