ODOT transferred SE 82nd Ave to PBOT's control at the beginning of the month.
At the moment, I don't think anything should be done, as OR 213 shields are still present along 82nd within Portland and on overhead street signs at major intersections, and treat this as a similar situation to OR 8 along Gales Creek Rd west of Forest Grove.
If anything, a point at SE Clatsop St (the dual Portland/Happy Valley and Multnomah/Clackamas County line) could be considered.
