The on and off ramps at I-5 exit 209 to Harrisburg will be closed overnight Aug. 3 through Aug. 8.
Crews will be paving and applying striping Sunday through Thursday from 6 p.m. to 6 a.m.
The Oregon Department of Transportation says drivers can detour around the closed ramps by using the exit before or after.
The overnight closures will only close one ramp at a time, and the ramps will be open during the day.
