Alexander Road in Princeton near the West Windsor border will be closed for just under six months starting in November so the state and county can replace two bridges and a culvert.
The projects are slated to start on Nov. 6 and end by April 20 of 2020.
Commuters are dreading the closure. Alexander Road was closed temporarily for utility work this spring and the closure created traffic jams on other roads and major delays.
The New Jersey Department of Transportation is replacing the bridge over the D&R Canal. Mercer County is replacing a culvert and the bridge over the Stony Brook. Princeton University gave $250,000 to the county to pay for design plans for the county project.
Each lane of the new bridge over the D&R Canal will be two feet wider, and there will be a five-foot shoulder on each side. Some residents welcome the widening of the bridge as a safety measure. The existing lanes are narrow, and Princeton University’s Tiger Transit buses must travel across the bridge.
The bridge over the D&R Canal was constructed in 1948. The three-span, simply supported bridge carries a timber deck overlaid with asphalt and rolled steel beams below a 6-foot wide timber sidewalk. The bridge has one travel lane in each direction and no shoulders, and is currently open to traffic with a 20-ton vehicle weight restriction. The bridge is located within the Delaware and Raritan Canal Historic District, the Camden and Amboy Railroad Branch Line, and Princeton Basin historic districts.
