Lechmere Viaduct Rehabilitation
The Lechmere Viaduct carries Green Line trains from Lechmere across the Charles River into downtown Boston. Streetcars first crossed the bridge in June 1912.
The bridge will be closed starting in May 2020 for 11 months as part of the adjacent Green Line Extension project. During this time, we will rehabilitate and replace track on the historic, concrete arched structure.
These upgrades will allow more trains to pass over the bridge, ultimately serving a completely new Lechmere Station and the new stations constructed as part of the Green Line Extension.
- Contract awarded: December 2019
- Construction start: January 2020 (full closure starts in May 2020)
- Projected completion: April 2021
- Budget: $61.8 million (construction only)

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.
We will strengthen the structure of the 110-year-old viaduct to handle heavier loads and increased train frequency while also preserving its historic facade. Work includes the complete reconstruction of track, signals, and traction power on the viaduct.
What You Can Expect During This Work
Starting in May 2020 and into 2021, shuttles will replace trains on the Green Line between Lechmere and North Station. Lechmere and Science Park stations will be closed.
