New Jersey Route 29 travels 34.71 miles from I-195/295 in Hamilton township to Frenchtown and Route 12. The state route is a nationally designated scenic by-way as it cruises along the beautiful Delaware River between the capital of Trenton and the city of Lambertville.

New Jersey Route 29 through Trenton includes a half mile tunnel beside Lamberton Street along the Delaware River. Opened on March 3, 2002, the tunnel was built as part of a $105-million project to reconstruct Route 29 southward from the city to Interstates 195 and 295. The tunnel project was delayed, taking four and a half years to complete with $15 million in additional costs. It was the final piece of the Trenton Complex project which included construction of Route 129 and the interchange between I-195/295 to the southeast.1

Views of the northbound tube of the New Jersey 29 tunnel at Trenton. Completion of the tunnel alleviated traffic congestion along Lamberton Road between the two existing segments of New Jersey 29 in South Trenton. Started in the 1960s, the 3.2-mile New Jersey 29 freeway was planned all along between Downtown Trenton and the exchange between Interstates 195 and 295. Until 1998, all but the 1.4 mile gap between the two segments was complete. Traffic used the two lane residential surface street of Lamberton Road between the two segments until 2002. The street was never a part of New Jersey 29 officially.2 10/03/04

Viewing the Washington Crossing Bridge from the southeast. Washington Crossing Road becomes General Washington Memorial Boulevard on the Pennsylvania side of the river. The local road ties into the intersection of Pennsylvaina 32 and 532. 10/03/04
Washington Crossing Road leaves the Washington Crossing Bridge and intersects River Drive. A wooden plank above the bridge end enforces a 6'6" height restriction for the bridge. Any car, truck, or van that hits the plank is subject to a moving violation and fine. Bridge officers staff a small office nearby and enforce the height restriction.
On our visit to the bridge, a mini van with a kayak strapped to its roof narrowly missed striking the plank. An officer we spoke with indicated that if the plank was hit, he would flag down the driver and call the state police who would then issue a traffic ticket. 10/03/04
