The Massachusetts Bay Transportation Authority (MBTA) has resumed Green Line service between North Station and Government Center.
The service resumption follows the removal of more than a hundred tons of debris directly above the Green Line after the partial collapse of a parking garage. MBTA structural engineers inspected the tunnel, took measurements and searched for any signs of damage above or below the surface.
Based on the comprehensive inspections, it has been determined that the Green Line tunnel, including the shared wall between the Green Line and Orange Line, is structurally sound. Following the successful testing of trains in the tunnel, Green Line service safely resumed between North Station and Government Center Station.
MBTA says structural engineers will continue to closely monitor the tunnel during daily Green Line operations. Green Line and Orange Line trains continue to bypass Haymarket Station while personnel complete some repair work on the standpipe system, which was damaged by debris from the garage collapse.
