Route 129 is a north-south expressway in the capital city of Trenton, New Jersey. The highway runs along Canal Boulevard through portions of Trenton, serving as an alternative highway to its parent, Route 29. The route begins at an intersection with South Lamberton Road in Hamilton Township, and heads northward along NJ Transit's River Line until terminating at an interchange with U.S. Route 1 (US 1; the Trenton Freeway).
The original use of Route 129 opened in 1961 on what is now Interstate 295 (I-295) from the Scudder Falls Bridge to Scotch Road in Trenton. The route was replaced in 1974 by I-95 (re-designated as I-295 in 2018), while the route's current incarnation opened in September 1993 along a former portion of the Delaware and Raritan Canal. The route has remained virtually untouched since its opening.
