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.
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.
