Closures of the Mount Washington Transit Tunnel and track work will cause a series of detours on rail and bus routes this weekend, Port Authority announced today.
The tunnel will close for maintenance from 11 p.m. Friday to 11 a.m. Saturday and again from the start of service Sunday until about 1 p.m. Rail service will detour via the old Allentown line. A free rail shuttle will operate between First Avenue and Station Square.
Buses will detour through Allentown on inbound trips and via the Wabash Tunnel traveling outbound.
The Red Line will have a separate detour from 6 a.m. to 6 p.m. Sunday during track work. Outbound trips will detour at South Hills Junction to the Blue Line. Shuttle buses will operate from South Hills Junction to Overbrook Junction and Willow Station.
