ABSTRACT
New York City is divided into five boroughs, only one of which is on the U.S. mainland. That fact makes the city dependent upon a network of bridges, tunnels, and roads serving those crossings. One of those roads, the Gowanus Expressway, part of the Federal Interstate Highway system, crosses Brooklyn, starting at the Verrazano-Narrows Bridge and ends at the divide of the Brooklyn Battery Tunnel and the Brooklyn Queens Expressway that connects to the Brooklyn, Manhattan, Williamsburg, and Triborough Bridges. Besides moving thousands of commuters to Lower Manhat-tan each day, the Gowanus Expressway is a major route taken by trucks moving goods into Manhattan. It is also the only interstate highway in Brooklyn, forming a corridor that connects the New Jersey Turnpike to the Long Island Expressway, carrying more than 200,000 vehicles a day, mostly trucks.
