A tunnel between Brooklyn and the Battery in Lower Manhattan was one of several traffic-relief projects in the late 1930s conceived by Mayor Fiorello H. La Guardia to remedy vehicular congestion on New York City’s existing thoroughfares. Extending just over 9,000 feet, the tunnel is the longest continuous underwater road in North America. Upon its construction, it has been featured in popular movies, served an essential purpose in one of the city’s darkest days, and was even the cause of some destruction. This New York City tunnel has been a part of many historic moments.
