PennDOT announced an upcoming bridge construction project on Route 8 in Middlesex Township, beginning on Monday.

The purpose of the project is to replace three bridges on Route 8. The project impacts approximately 1.5 miles. Motorists can expect changes to the traffic patterns throughout the project.

The contractor, Plum Contracting of Pittsburgh, plans to begin temporary widening of the northbound Route 8 shoulder.

The project includes the replacement of three existing structures carrying Route 8 over the south branch of Glade Run and two unnamed tributaries to Glade Run.

Construction will impact the area from the Allegheny/Butler county line to 1.4 miles south of Cooperstown.

There will be both daylight and night work associated with this project. Message boards will be placed north and south of the project with details regarding ongoing work.

Two bridges will be replaced in 2021 and the third one will be replaced in 2022.
