New Jersey Route 129

Route 129 is a north–south expressway in the capital city of Trenton, New Jersey. It runs along Canal Boulevard through parts of Trenton and serves as an alternative to its parent highway, Route 29. The road starts at an intersection with South Lamberton Road in Hamilton Township and goes northward along NJ Transit's River Line until it ends at a connection with U.S. Route 1, also known as the Trenton Freeway.

Originally, Route 129 opened in 1961 on what is now Interstate 295 from the Scudder Falls Bridge to Scotch Road in Trenton. In 1974, this section was replaced by I-95, which was later redesignated as I-295 in 2018. The current version of Route 129 opened in September 1993 along a part of the old Delaware and Raritan Canal and has stayed mostly the same since then.

Route description

Route 129 starts at a road called South Lamberton Road near the Delaware River in Hamilton Township. It goes north as a road with two lanes in each direction, passing fields and trees. It follows a train line called the River Line and runs close to another highway, Route 29.

As Route 129 continues, it becomes a four-lane road and goes through parts of the city of Trenton. It passes factories, homes, and a train station called Cass Street station. The road ends where it meets another big highway, US 1, and turns into the Trenton Freeway.

History
