Spring Valley Summit is a mountain pass in southwestern Idaho, United States, at an elevation of 4,242 feet (1,293 m) above sea level on State Highway 55, the Payette River Scenic Byway.[1]
It is located in southwestern Boise County, south of the city of Horseshoe Bend, 1600 vertical feet (490 m) below. The summit marks the divide between the Payette River and Boise River drainage areas. The new multi-lane grade of Highway 55 into Horseshoe Bend was completed in fall 1991;[2] the old curvier road is to the west, long plagued by landslides and closures.[3] Of the major grades from Boise to north Idaho, it was the last to be improved. The other three, all on U.S. 95, were White Bird Hill (1975), Lapwai Canyon (1960), and Lewiston Hill (1977).
The north side of the summit is also known as Horseshoe Bend Hill.[citation needed]
