Many of the major cities in the U.S. got their start as big port cities. Ships could sail in, deposit goods, and flood the local economy with raw materials and other goods. They were ports because a bay or river brought the ship. And because there was water, there was a need for bridges. Bridges as an architectural or engineering feature have been around since the Romans, but new materials in the 19th century allowed for better, stronger, longer bridges to be built. In the United States, there are several iconic bridges—The Golden Gate Bridge, The Brooklyn Bridge, The George Washington Bridge—whose conception and completion are due in large part to the engineers who first thought them up. Henry Petroski’s Engineers of Dreams is an ode to these thinkers and builders, the men who decided to cross a river and leave their mark on the American landscape.
