The outbound Armstrong Tunnel in Pittsburgh has reopened to traffic, and the inbound tunnel has closed to traffic. Closure of the inbound tunnel, which is expected to reopen in June 2025, is required for crews to complete miscellaneous construction, including additional roadway work.

While the outbound tunnel has reopened, the sidewalk on that side of the tunnel is expected to remain closed through September. The sidewalk work associated with the rehabilitation project has been completed. However, Duquesne University will be using scaffolding in the area to make repairs to the Fisher Hall pedestrian bridge above Forbes Avenue.

During the inbound Armstrong Tunnel closure, vehicles will be detoured using Second Avenue, Ross Street, and Forbes Avenue. Until the sidewalk reopens, pedestrians will continue to be detoured using Forbes Avenue, Ross Street, and Second Avenue.
