简单介绍
The I. B. Perrine Bridge at Twin Falls, Idaho, United States, is a truss arch four-lane bridge carrying U.S. Highway 93 over the Snake River Canyon. Perrine Bridge is approximately 1,500 feet (457 m) long and 486 feet (148 m) above the Snake River. The elevation of the road deck is approximately 3,600 feet (1,097 m) above sea level. The bridge serves as the Twin Falls area's main link to Jerome County and Interstate 84.
Originally named the Twin Falls-Jerome Intercounty Bridge, a steel cantilever bridge was opened to traffic in September 1927, and at the time, was the highest bridge in the world. The privately financed $650,000 structure was originally a toll bridge, but the tolls were eliminated in 1940 after the bridge was purchased by the state of Idaho. |
