Perrine Bridge, Twin Falls, Originally named the Twin Falls-Jerome Inter-county Bridge, a steel cantilever bridge was opened to traffic 90 years ago in September 1927; at the time it was the highest bridge in the world.

By the early 1970s, the original bridge was outdated and unable to handle heavy loads and required replacement. Construction on the current bridge began in May 1973 and was completed forty-one years ago in July 1976 at a cost of $9.7 million, and the original cantilever bridge to the west was disassembled.

The Perrine Bridge is approximately 1,500 feet (457 m) in total length, with a main span of 993 feet (303 m) and a deck height of 486 feet (148 m) above the Snake River it is the eighth highest bridge in the United States. The elevation above sea level for the bridge deck is approximately 3,600 feet (1,100 m).

The bridge is named for I. B. Perrine (1861–1943), who spearheaded the early 20th century irrigation projects in the Magic Valley region and is largely credited as the main founder of Twin Falls. a statue of Perrine is at the visitors’ center at the south end of the bridge.
