Route 28 Highland Park Interchange Project
The purpose of the project is to address the existing bottleneck and congested traffic flow on Route 28 (Allegheny Valley Expressway) and other operational and safety issues within the Route 28/Highland Park Bridge/Freeport Road Interchange.
The project involves reconstruction of Route 28 between North Canal Street/Kittanning Pike and extending north/east to the Delafield Avenue Interchange, the reestablishment of two travel lanes on Route 28 in each direction through the interchange, and construction of improved acceleration and deceleration ramps. Also included in the project is the reconstruction of the Route 28 ramps with the Highland Park Bridge and Freeport Road, bridge/wall preservation work, bridge, and roadway widening, sound barriers, and miscellaneous operational and safety improvements.
The Highland Park Bridge river crossing and the Riverfront 47 Development are not part of this project
