Triborough BridgeThe Triborough Bridge is a New York City complex of three bridges connecting the boroughs of the Bronx, Manhattan, and Queens. The bridges span the East River Harlem River, and Bronx Kill. and Construction was begun in 1930, but was soon sidetracked by the Great Depression. Using New Deal money, the project was resurrected in the early 1930s by Robert Moses and the bridge was opened to traffic on July 11, 1936. Its cost was greater than that of the Hoover Dam.
The structure used concrete from factories from Maine to Mississippi. To make the casings for pouring the concrete a whole forest in Oregon was cut down.
The Triborough Bridge's toll revenues were and are enormous. The money from the bridge gave Moses his power and today pays for most of New York City's public transit subsidy. The bridge carries approximately 200,000 vehicles per day.
The bridge is operated by MTA Bridges and Tunnels.
