A previous alignment through Boring ran due west onto Fireman Way, curving south onto 272nd. Two junctions with 257th Ave give away an old alignment. OR 212 traveled due west on the eastern junction with 257th, curving south to meet the western junction. Armstrong Circle at 172nd is a previous alignment. Before the construction of I-205, OR 212 continued west on a shared alignment with
OR 213 to
Oregon City. There, it crossed the
Willamette River into
West Linn and continued west to
Tualatin where it eventually terminated at an intersection with
OR 99W. This section replaced the original
Oregon Route 244, but was eventually
decommissioned after I-205 was completed; however the entire route can still be driven (other than a now-closed bridge across the
Clackamas River which used to connect Oregon City with
Gladstone, Oregon). Before US 26 was rerouted, it used to run on Orient Drive. OR 212 traveled this brief segment of Compton Road before the US 26 realignment shortened it. ==Major intersections==
