The Port Authority of New York and New Jersey has morphed in ways that would be unrecognizable to its founders. Its mission evolved from improving rail freight to building motor vehicle crossings, airports, office towers, and industrial parks and taking control of a failing commuter rail line. Despite its criticisms and travails, the Port Authority has overcome hurdles that had frustrated other public and private efforts, built the world's longest suspension bridge, and taken a leading role in creating an organization to reduce traffic delays in the New York-New Jersey region. Drawing on 100 years of history, Philip Mark Plotch and Jen Nelles produce a significant and engaging account of a powerful governmental entity that offers durable lessons on collaboration, leadership, and overcoming complex political challenges in modern America.
