River tunnels, steel arches, and traces of the harbor
New Jersey keeps the other side of New York Harbor visible: a lawn remembers an explosion, a steel arch raised its roadway for larger ships, square towers ventilate a river tunnel, and a waterfall still carries the sound of an industrial engine.

The blast across the harbor
A munitions blast from this quiet lawn once shook Manhattan.
In July 1916, a large stockpile of munitions exploded at the Black Tom docks. The shock wave reached Manhattan and damaged the Statue of Liberty; investigators later attributed the attack to German sabotage.
This steel arch lifted its own deck to clear larger ships.
When the Bayonne Bridge opened in 1931, it was one of the world's longest steel arch bridges. Between 2013 and 2019, the Port Authority raised its roadway about 64 feet within the existing arch so larger container ships could enter the harbor.
This brick tower is one lung of the Holland Tunnel.
When the Holland Tunnel opened in 1927, mechanical ventilation solved the problem of vehicle exhaust accumulating under the river. New Jersey's ventilation buildings pull fresh air in and push polluted air out for a tunnel hidden below.
