Idaho State Highway 55
State Highway 55 (SH-55) is an Idaho highway from Marsing to New Meadows, connecting with US-95 at both ends.
From Marsing it travels east to Nampa, Meridian, and Eagle, then north to Horseshoe Bend. SH-55 then climbs the Payette River to Banks, then its north fork to the Long Valley, through the towns of Cascade and McCall. After descending a narrow canyon to Meadows, SH-55 terminates in New Meadows at the junction with US-95.
In the southwest corner of Idaho, State Highway 55 starts at the junction with US-95, approximately two miles (3 km) west of Marsing, at an elevation of 2,305 feet (703 m) above sea level. The highway heads eastward as it travels through Marsing, crosses the Snake River and the Snake River Valley AVA. The highway continues east to Nampa (mostly as Karcher Road), where it meets Interstate 84 and US-30.
The highway is cosigned with those routes as it heads eastward to Meridian. SH-55 turns northward at Eagle Road and crosses the Boise River near Eagle. The junction with SH-44 is in Eagle, where the routes are briefly cosigned.
East of Eagle, SH-55 turns northward and climbs to the Spring Valley and over the Spring Valley Summit at 4,242 feet (1,293 m), then descends 1,600 vertical feet (490 m) on Horseshoe Bend Hill into Horseshoe Bend. The new multi-lane grade was completed in late 1991; the old curvier road to the west was long plagued by landslides and extended closures. North of Horseshoe Bend, the highway ascends the Payette River and passes through several recreational areas, which offer rafting, fishing, and camping activities. SH-55 continues north, through the small communities of Banks and Smiths Ferry, then crosses the river via the Rainbow Bridge (built in 1933), originally known as the North Fork Bridge.
SH-55 then climbs Round Valley Creek to Round Valley, and continues northward through the extended Long Valley of Valley County to the county seat of Cascade. It ascends a brief summit at 5,207 feet (1,587 m) at Little Donner then descends to follow the east shore of Cascade Reservoir. The route continues northward to Donnelly, the turnoff for Tamarack Resort, located to the southwest, on the western shore of the reservoir. SH-55 continues north through the valley to McCall, at the south shore of Payette Lake, the host of many scenic, recreational, and winter activities.
Meeting the south shore of Payette Lake, State Highway 55 turns westward as Lake Street through McCall and its west "Lardo" area. West of town, the road climbs to the Red Ridge, where it reaches its maximum elevation of 5,324 feet (1,623 m) at the Adams County line, also known as Goose Creek Summit immediately northeast of the Little Ski Hill.
Two miles (3 km) further is the turnoff for the Brundage Mountain ski area, four miles (6 km) north on Goose Lake Road. SH-55 then heads west and enters a narrow and twisty canyon, rapidly descending with Little Goose Creek to Meadows, then to its northern terminus, the junction with US-95 in New Meadows at 3,868 feet (1,180 m) in Meadows Valley.
