The third and final full closure is schedule to occur from 9 p.m. Thurs. June 1 to 5 a.m. Mon. June 5, according to PennDOT.

The Chartiers Bridge replacement project on Washington Pike, at the border of South Fayette and Bridgeville, will occur during three extended weekend closures, starting on Thursday, April 13, 2023. The work represents the final stages of the project, which will improve traffic flow on and around the bridge and the adjacent I-79 interchange.

PennDOT will confirm each closure in advance, as the schedule may need to change due to environmental or other factors that would affect the work.

Weekends #1 & #2

  • Done

Weekend #3

  • Lane restrictions on bridge 6 p.m. to 9 p.m.
  • Full closure from 9 p.m. Thurs. June 1 to 5 a.m. Mon. June 5

During the full closure periods, a pedestrian shuttle van will be available every 30 minutes.

Local police will assist motorists at various intersections between Route 50 in South Fayette Township and the I-79 ramp in Collier Township.

To allow bridge work to occur, Chartiers Street between Route 50 and Dewey Avenue and Church Street at Route 50 will be required to close the entire weekend.

Chartiers Street traffic will be detoured via Route 50, Station Street, Dewey Avenue and Bank Street.

Church Street traffic will be detoured via Station Street and Chess Street.

The sidewalks on the bridge will close to pedestrian traffic from 1 p.m. Thursday continuously through 5 a.m. Monday morning. A temporary pedestrian shuttle will provide service during the weekend as the bridge sidewalks will be closed. The hours of service will occur from 6:30 a.m. to 10 p.m. each day.

The pedestrian stops will be located in the following locations:

  • The intersection of Route 50 and James Street in Bridgeville

Pickup times at the designated shuttle stops will not exceed 30-minute cycles.
