From 4/15/2019 news release:
The project widens the roadway from two to four lanes throughout most of the project limits, including horizontal realignment in order to reduce the overall horizontal curvature and severity of the grade as the roadway ascends away from the Allegheny River. The tentative completion is in December 2020. The contractor on this $15.4 million project is Plum Contracting, Inc.
