The ramp work is part of the $47.31 million improvement project that will address the existing bottleneck and congested traffic flow on Route 28 at the Highland Park Bridge interchange. The project, which started in late 2020, involves the reconstruction of Route 28 between North Canal Street/Kittanning Pike and Delafield Avenue, the establishment of two travel lanes in each direction through the interchange, and the reconstruction of acceleration and deceleration ramps. The project also features the reconstruction of ramps at the Highland Park Bridge/Freeport Road interchange, bridge and wall preservation work, roadway widening, sound barrier installation, and miscellaneous operational and safety improvements. Lane restrictions on Route 28 and long-term ramp closures will occur throughout the project which is expected to conclude in late 2023.
