82nd Avenue,[1] a major five-lane thoroughfare through east Portland, until reaching its other end at OR 224 in the Clackamas area.

It then proceeds south on a four-lane expressway through a scenic canyon on Oregon City's eastern edge until it intersects with Molalla Avenue in the vicinity of Clackamas Community College.

This route goes by a number of names, known alternately as 82nd Drive, the Oregon City Bypass or the Trails End Highway.

Approximately 12 miles (19 km) south of Molalla, the highway enters the town of Silverton, where it intersects Oregon Route 214.

A separate roadway (never maintained by the Oregon Department of Transportation) known as the Cascade Highway South[4] continues south from Silverton (previously Oregon Route 215 but now devoid of any route number)[citation needed] until an intersection with OR 22 just north of Stayton.
