Fenway Portal Project

Crews at Fenway Portal
  • Between September 2019 and early 2020, we are adding large steel doors to the entrance of the Green Line tunnel near Fenway Station to prevent flooding. Crews will also install an updated pumping station, and new cameras to monitor potential flooding of the Muddy River and rising water levels that could pose a flood risk to our system.
  • Contract awarded: March 2018
  • Projected completion: Spring 2020
  • Budget: $22,187,285
  • Status: 50% construction complete

As part of the Green Line Transformation (GLT), this project meets the following goals:

  • Safety and resiliency: Reduce risk of damage from flooding on the Green Line; fewer weather-related service interruptions

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.

This project is one of many we're working on to ensure twice as many passengers have access to a safer, more comfortable, and more reliable Green Line by 2030.

Why We’re Doing This Work

The Fenway Portal, the entrance to the Green Line tunnel next to Fenway Station, is subject to flooding due to its location near the Muddy River. In 1996, significant flooding caused almost $70 million in damage and shut down major portions of the Green Line. Repair work lasted for 2 months.

Temporary flood prevention measures have been in place since then, but these steel doors will allow us to respond more quickly and efficiently if the Muddy River floods, and will enable a rapid return to service when flood waters recede.

When and Where We’re Doing This Work

Construction will require the temporary closure of the Green Line D Branch. Bus shuttles will replace Green Line service August 26, 2019 – early January 2020 on many weekends and weeknights.

Service shutdowns are also being coordinated with track and signal replacement on the D Branch and accessibility work at Newton Highlands. The shuttle schedule is subject to change due to weather, construction progress, and Red Sox home games—we will start shuttle service later to accommodate increased ridership after evening games.

We will share specific dates and times in advance on our Green Line D Shuttle schedule page, and you can always check Green Line D alerts while planning your trips.
