Perrine Bridge, Twin Falls, Idaho

The I. B. Perrine Bridge is a four-lane truss arch span in the western United States. Located at Twin Falls, Idaho, it carries U.S. Highway 93 over the Snake River Canyon, connecting to Jerome County and Interstate 84.

 

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.

 

Tourism

 

Located at the southwest end of the Perrine Bridge is the Twin Falls Visitor Center featuring souvenirs and gifts, Idaho products, visitor information, and interactive exhibits highlighting the recreational and historical activities and attractions in the region. The visitor center has views of the canyon, bridge, and access to the trail system along the canyon rim. Trails go under the bridge on either side which offers vantage points of the bridge and its structure.

 

To the east, along the south rim of the canyon, lies the dirt ramp used by Evel Knievel when he unsuccessfully attempted his Snake River Canyon jump on the Skycycle X-2 in September 1974; the jump failed because of a parachute malfunction. The ramp where he made the leap sits on private property about 1.6 miles (2.6 km) east of the bridge and is visible from the bridge as well as various vantage points along the Canyon Trail. A memorial to Knievel is located near the bridge; it was dedicated in September 1985, at a small ceremony attended by Knievel.

 

BASE jumping

 

The Perrine Bridge is a popular BASE jumping site known all over the world; it may be the only man-made structure in the United States where BASE jumping is allowed year-round without a permit. Jumpers often use the nearby visitor center as a home base before and after parachuting from the bridge.
