Final paving begins on long overdue Mount Rose Avenue/I-83 project Final paving has begun on the long overdue Mount Rose Avenue/Interstate 83 interchange project. The state Department of Transportation on Friday confirmed that Cherry Hill Construction has begun final paving on Mount Rose Avenue. Although no new completion date was announced, Cherry Hill has said in the past that it could complete the project within 90 days once it starts the final paving. "The contractor has not provided a revised schedule update, however they have indicated they will complete the final paving of I-83 mainline and the ramps by the end of summer/early fall," PennDOT spokesperson Dave Thompson said in a statement.
