Route 978 Millers Run Road Temporary Bridge Opened to Traffic in South Fayette Township

02/17/2023

Pittsburgh, PA – PennDOT District 11 is announcing the opening of the temporary bridge on Millers Run Road (Route 978) over Dolphin Run in South Fayette Township, Allegheny County.

The one-lane temporary bridge has opened to traffic. As a safety precaution, a 10-mph speed limit will be implemented in the area of the temporary structure. Traffic will be controlled by temporary signals. The Millers Run Road Bridge closed to traffic in December after an inspection found advanced deterioration of the structure. A project to permanently replace the closed bridge is currently being designed.

Mohawk Road will remain closed to traffic at the Millers Run Road intersection until the permanent structure is installed.

The temporary structure will not be weight posted; however, the truck detour will remain in place.
