Moyie River Canyon
Constructed in 1964, the 1223 ft. long steel truss bridge spans the Moyie River Canyon at a height of 464 ft. It replaces the old bridge built in 1923 and 1.25 miles of narrow, winding highway. It is the second highest bridge in Idaho, exceeded only by the 476 ft. high Perinne Memorial Bridge across the Snake River near Twin Falls.
The power dam, constructed by the City of Bonners Ferry, supplies electricity to the surrounding area. The original dam built in 1921 was razed in 1959 on completion of the new dam. The spillway is 83 ft. high and the drop is 212 ft. from top of dam to lower pool. Niagara Falls has a drop of 168 ft.
The 100 mile long Moyie River has its headwaters in British Columbia and flows to the Pacific Ocean by way of the Kootenai and Columbia Rivers.

One of the highest deck truss bridges in the world, the Moyie River bridge is located just south of the Canadian border in the U.S. state of Idaho. Far less known than the Perrine bridge in Idaho Falls, the Moyie crossing is nearly as high at 464 feet (141 mtrs). Constructed in 1964, the current span bypassed more than a mile of twisting road that descended to the bottom of the canyon where it crossed a bridge built in 1923. The Moyie River begins in British Columbia, Canada and flows into the Kootenai before meeting the Columbia River which empties into the Pacific Ocean.
