Light Rail Transit service and several bus routes will be detoured by a nighttime closure of the Mount Washington Transit Tunnel on Sunday, Port Authority announced.
The tunnel will be closed for fan replacement from 8 p.m. until the end of service. Red Line and Blue Line service will operate only as far north as South Hills Junction. Bus shuttles will operate in both directions between South Hills Junction and Station Square, and subway local service will operate in both directions between the North Shore and Station Square.
Several bus routes will detour, but most regular stops will be maintained.
