AMP: Parma Spur Hwy #489/15
Location: OR 452 and Old SH-18, Malheur Cty
No reassurance shield as Oregon 452 begins. 452 takes over for what was once Idaho SH-18, which went up to Parma via Roswell.
Location: OR 452 and OR 454, Malheur Cty
A little over a mile later, we’ll approach Oregon 454. Stay straight to follow that back to Idaho. Turn right to head over the Snake River to Adrian.
