OR 82 begins at an intersection with U.S. Route 30 (Adams Avenue). It heads east underneath Interstate 84 into Island City, where it turns north at an intersection with OR 237, which continues east to Cove. Once out of Island City, it curves northeast and passes through Imbler, Elgin, and enters Wallowa County at Minam. From there, the highway curves southeast into the Wallowa Valley, passing through the towns of Wallowa, Lostine, and Enterprise before ending in Joseph. OR 351 from Joseph to the Wallowa Lake State Park at the south end of the Lake was originally part of the OR 82 Highway.
