Following a comprehensive inspection of the infrastructure by internal and third party engineers and safety experts, an intensive assessment of the repair work performed, and subsequent testing of trains in the tunnels, the MBTA’s team of structural engineers have determined it is safe for both Orange and Green Line train services to resume, effective immediately.

The Government Center Garage developer has installed the necessary supports to uphold the structure. Based on comprehensive inspections of the repair work, structural engineers and safety experts have deemed the structures and the surrounding infrastructure to be structurally sound. Following the successful testing of trains in the tunnel, Green Line and Orange Line train service can safely resume. Structural engineers will continue to closely monitor the tunnel and infrastructure during daily Orange and Green Line operations.

The MBTA thanks all of its riders for their patience during this service disruption, infrastructure assessment, and service restoration.
