The Port Authority announced that the Mount Washington Transit Tunnel will be closed for rail maintenance Saturday and Sunday. Light-rail service and several bus routes will be detoured.
All rail cars will use the former Allentown route, bypassing Station Square. Rail shuttles will serve Station Square, Downtown and the North Shore. Delays of around 10 minutes should be expected.
Seven Port Authority bus routes will be detoured inbound via Arlington and Warrington avenues and outbound via the Wabash Tunnel, with minor temporary stop changes.
