New Jersey Route 129 - Route Description

Route Description

Route 129 begins at an intersection with Lamberton Road on the Delaware River in Hamilton Township. The highway proceeds northward, passing through small fields and tree patches until reaching railroad tracks, where the route turns to the northwest, paralleling its parent, the Route 29 Freeway to the west. Route 129 then becomes a divided highway, intersecting with an onramp to Route 29 and passing to the east of a large factory. From there, the highway merges back together and comes upon a full interchange with Route 29. Route 129 itself continues along the railroad tracks on Canal Boulevard, entering the city of Trenton, where it becomes a divided highway once again.

At an intersection with Mercer County Route 650 (Lalor Street), Route 129 develops a grassy median and heads along the industrial portion of the city. With New Jersey Transit's River Line paralleling the highway, the state road serves access to large factories, a large residential district and a train station between Lalor Road and Cass Street. Route 129 continues northward along Canal, crossing under U.S. Route 206 (South Broad Street) with a southbound exit to that road. It crosses Hamilton Avenue before reaching an interchange with U.S. Route 1, where Route 129 ends and Canal Boulevard's right of way merges into the Trenton Freeway.
