Please note: South Fayette Township is not directly involved with this project but will share updates from PennDOT as they are available.
SUMMARY: A temporary, one-lane bridge with traffic lights opened Feb. 16 on Millers Run Road, near its intersection with Battle Ridge Road. In addition, Mohawk Road is fully closed at its intersection with Millers Run Road.
The Pennsylvania Department of Transportation (PennDOT) has installed a temporary one-lane bridge over Dolphin Run on Millers Run Road, near its intersection with Battle Ridge Road, in South Fayette Township.
Temporary traffic lights control one-lane, alternating traffic over the bridge. Speed limit in the area is 10 MPH.
There is no weight limit, but a detour remains in place for trucks and buses. Emergency vehicles may use the bridge when necessary. (Note: The original news stating the bridge had a 10-ton weight limit was incorrect.)
The temporary bridge is adjacent to the Dolphin Run bridge on Millers Run Road that is closed due to advanced structural deterioration.
Mohawk Road is closed to traffic at its intersection with Millers Run Road until the permanent bridge is installed--a project expected to take approximately 18 months to two years. Local traffic can access Mohawk Road from Battle Ridge Road only.
