State Highway 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. ==Route description== In the southwest corner of Idaho, State Highway 55 starts at the junction with US-95, approximately 2 miles (3 km) west of Marsing. 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, where it meets Interstate 84 and US-30. The highway is cosigned with those routes as it heads eastward to Meridian. Highway 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, Highway 55 turns northward and climbs to the Spring Valley and over the Spring Valley Summit, at ((web-cam )), then descends 1600 vertical feet (490 m) on ''Horseshoe Bend Hill'' into Horseshoe Bend. The new multi-lane grade was completed in fall 1991; the old curvier road is to the west, long plagued by landslides and closures. North of Horseshoe Bend, the highway ascends the Payette River and passes through several recreational areas, which offer rafting, fishing, and camping activities. Highway 55 continues north, through the small communities of Banks and Smiths Ferry ((web-cam )), then crosses the river via the Rainbow Bridge (1933) ((photo )), 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 at ''Little Donner'' ((web-cam )), 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, 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 above sea level, immediately northeast of the Little Ski Hill, also known as ''Goose Creek Summit'' ((web-cam )). Two miles (3 km) further is the turnoff for the Brundage Mountain ski area, four miles (6 km) north on Goose Lake Road. Highway 55 then 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 in Meadows Valley. Highway 55, from Eagle north to US-95 in New Meadows, is the Payette River Scenic Byway,〔(Idaho Byways - Payette River Scenic Byway )〕 part of the National Scenic Byways Program. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Idaho State Highway 55」の詳細全文を読む スポンサード リンク
