Port Mercer was a small town along the Delaware and Raritan Canal in central New Jersey. Since the canal closed down in 1932, commerce has shifted east to U.S. Route 1, where shopping malls, car dealers, and restaurants are now located. On the west side of the canal, there are still extensive swampy wetlands between Lawrence Township and Princeton.
This little suspension bridge, which spans the attractively named Waste Weir, was built by the Roebling Company. While some internet sources say it is a miniature replica of one of Roebling’s more famous projects, either the Brooklyn Bridge or the Niagara Bridge. Although it uses the same suspension technology, the design is not identical. Other sources say it was built to demonstrate suspension technology, and then given to the city of Trenton. I haven’t seen a firm date for when it was built.
The Shaky Bridge sits between the Delaware River and Route 29 in Stacy Park. Route 29 runs over the alignment of the Trenton Water Power, a seven mile long canal completed in 1834 – the same year as the 65 mile long D&R Canal.
These three small houses are located along the Delaware and Raritan Canal in Trenton, where movable bridges formerly crossed the canal. Houses were provided so the bridgetenders were always available to swing the bridge out of the way as a canal barge passed through.
The Hanover Street house was renovated when Thomas Edison State College built the large building that partially surrounds it. The Calhoun Street house appears to be stabilized, while the Prospect Street house looks occupied.
