Karns Crossing Bridge Replacement Project​


Project Overview

The Route 68 Karns Crossing bridge replacement project is located within Butler and Summit Townships, Butler County.  The project involves two separate structures that will be affected as part of this project.  The first structure is the 12-span Karns Crossing Bridge which carries SR 0068 over the Bessemer & Lake Erie Railroad and the Buffalo & Pittsburgh Railroad in Butler and Summit Townships.  The second structure is the Twin-Cell Arch Culvert which carries SR 0068 over the Connoquenessing Creek in Summit Township.  

The purpose of this project is to address identified deficiencies along SR 0068 between SR 0422 and Hospital Way. Traffic safety issues at the SR 0068 / Delwood Road Intersection and SR 0068 / SR 0422 EB Onramp Intersection will be corrected. The new Karns Crossing Bridge will be raised to provide the necessary vertical clearance required over the railroads. One lane of traffic in each direction along SR 0068 will be maintained during construction. A short term detour will be implemented for Delwood Road for a portion of the project.
