Indiana, PA – The Pennsylvania Department of Transportation (PennDOT) announced today that new traffic patterns will be implemented along Route 68/East Jefferson Street on November 24 for the Karns Crossing Bridge Project in Summit and Butler townships, Butler County.
The second phase of the Karns Crossing Bridge Project will begin with lane shifts onto the new temporary Route 68 near Delwood Road and traffic signal changes at the Route 422 eastbound on and off ramps. The speed limit will be reduced to 30 miles per hour through the construction zone during Phase 2 of construction.
The existing eastbound lane on the Karns Crossing Bridge will be closed effective November 24 at 9:00 AM and traffic will be shifted into the westbound lane. Two lanes of traffic will be maintained, and Delwood Road will remain closed until November 1, 2026. To access Delwood Road from the west, motorists will take Route 8 north and turn right onto East Brady Street, travel approximately 1.25 miles and turn right onto Delwood Road.
The traffic changes are weather dependent. In the event of inclement weather, the alternate date for the changes will be November 25. Motorists should use caution in the area.
Contractor, Swank Construction Company, New Kensington, PA, will be completing this $64.8 million bridge replacement project, estimated to be completed in spring 2028.
The Karns Crossing Bridge project will replace two separate structures - the bridge itself that carries Route 68 over the railroad lines and the adjacent arch culvert over the Connoquenessing Creek. It also includes traffic safety and capacity improvements at the Route 68/Delwood Road intersection and the Route 68/US 422 eastbound on-ramp intersection.
