Washington Road crosses over Stony Brook here, and it's a great place to stop and enjoy the view. The wide shoulder and sidewalk along the side of the bridge allow you to stop safely without worrying about oncoming traffic.

This short bridge over the canal takes you to a rebuilt home from 1799 that now functions as a restroom with water fountains and air conditioning. This is a great little scenic rest stop along the canal trail.

Washington Crossing the Delaware River statue is located on the corner of River Road and Route 532. This statue is based on Emmanuel Leutzeโ€™s famous painting of the nation's first president, George Washington, crossing the Delaware River. The statue was quite a feat to bring to this small town, as it weighs 30 tons. It was carved by a 76-year-old retired limestone sculptor in the 1970s.

The Washington Crossing Bridge spans the Delaware River, connecting the historic Washington Crossing Parks in New Jersey and Pennsylvania. This narrow iron truss bridge, built in 1904, accommodates two lanes of traffic with a 3-ton weight limit and a 15 mph speed limit. It has a 3'6" wooden pedestrian walkway, and traffic signals at each end manage the flow of vehicles due to the bridge's narrowness. The Delaware River Joint Toll Bridge Commission has recently announced plans to replace the bridge to address safety and operational issues. The new design will feature wider lanes, shoulders, and a pedestrian path, aiming to improve traffic flow and safety while still respecting the area's historical significance.
