10 Seconds of Williamsburg Bridge

The Williamsburg Bridge has an unconventional structure among suspension bridges; though the main span hangs from cables in the usual manner, the side spans leading to the approaches are supported by trusswork, drawing no support from the cables above. The entire bridge is 7,308 feet long, including approaches, and the deck is 118 feet (36 m) wide. The height at the center of the bridge is 135 feet (41 m) and each tower is 310 feet (94 m), measurements being taken from the river’s surface at high-water mark. Construction on the bridge began in 1896, with Leffert L. Buck as chief engineer, Henry Hornbostel as architect and Holton D. Robinson as assistant engineer, and the bridge opened on December 19, 1903 at a cost of $24,200,000.
