The MBTA will take the elevators out of service at the Porter Square T station for approximately one year beginning Monday while work is underway to replace and add additional elevators.
The station will remain open during the construction, but because of the elevator service interruptions the MBTA will be providing shuttle buses between the Porter Square and Davis Square stations for customers who need to ride elevators.
The $11.5 million project is being done as part of the 2006 settlement of a federal lawsuit filed by 11 individuals and the Boston Center for Independent Living over inadequate accessibility for the disabled to MBTA trains and buses.
As part of the settlement, the MBTA agreed to construct additional elevators at the heavily traveled stations at Harvard, State, Porter, Downtown Crossing and Park Street, according to MBTA spokesman Joe Pesaturo.
At Porter Square, the MBTA has hired Sharon-based Walsh Construction Company to replace three elevator cabs and related equipment and construct two new elevators. One of the new elevators will approach a bridge crossing over the commuter rail and connect the street level to the lobby. The second elevator will connect the lobby to the Red Line platforms.
A bathroom and ductwork will be relocated to accommodate the project, and the sidewalk along Massachusetts and Somerville avenues will be regraded around the station. Stairways will be adjusted to accommodate the new sidewalk grading, according to the MBTA.
The MBTA expects federal funding to cover about 80 percent of the project costs.
Shuttle bus service at the Porter Square T stop will be located on the Somerville Avenue side of the station. In Davis Square customers seeking the shuttle bus should ask the station official and catch the bus in the busway.
