    Truncation Of Regular Rail Service At First Avenue Station; Temporary Bus Replacement Routing Between First Avenue & Steel Plaza Stations; Temporary Rail Subway Local Replacement Route Between Allegheny & Steel Plaza Stations - Jailhouse Tunnel (Downtown Subway) Switch and Signal Replacement

    Begins: 10/24/2026
    Ends: 10/25/2026
     

    Summary:

    Pittsburgh Regional Transit, and its Way Department, to replace a switch and signal in the "Jailhouse" trolley tunnel, will close a portion of the Downtown Subway between First Avenue and Steel Plaza Stations beginning Saturday morning, October 24, 2026.

    Known locally as the "Jailhouse Tunnel", the former railroad and canal tunnel that begins and ends the Downtown Subway near Fourth Avenue in Downtown Pittsburgh is too narrow to allow simultaneous presence of moving light rail trains and workers, thus requiring its full closure beginning Saturday morning, October 24, 2026, through early Sunday morning, October 25, 2026.

    Work in the tunnel will require its complete closure, necessitating the short turns of regular rail service at First Avenue Station.

    To assist in the continuation of travel into Downtown and the North Side, a temporary bus replacement service between First Avenue and Steel Plaza Stations, as well as a temporary Subway Local rail replacement service between Steel Plaza and Allegheny Stations will be provided.

    Work efforts, the closure and service adjustments will begin on Friday night, October 23, 2026, following completion of rail service for the night.

    The rail turnback and replacement services will begin with the start of service Saturday morning, October 24, 2026, until Sunday Morning, October 25, 2026, at the start of service.
