Clackamas County closing southbound lane of South End Road effective 10 a.m., April 13; detour in place

Clackamas County is temporarily closing the southbound lane of South End Road between 5th Avenue and Barker Avenue in Oregon City, effective 10 a.m., Thursday, April 13. This section of road, which has a long history of grade changes and shallow slide activity, continues to move due to the heavy winter rains.

The detour route for southbound traffic will be north on High Street, south on 5th Street, south on Linn Avenue and west on Warner Parrott Road.

The lane closure will continue until the county is able to do short-term pavement repairs, once there is a period of dry weather. While the paving repairs are being done, the road will be totally closed during daytime hours. Both northbound and southbound detours will be posted during the full closure.

Transportation Maintenance Manager Randy Harmon says, “We will open the southbound lane once the temporary repairs are complete. But if the area continues to slide, we may have to close it again. The safety of the traveling public is our top concern.”

An engineering geologist hired by the county is assessing the area to identify appropriate short-term and long-term repairs. The assessment includes monitoring ground movement and ground water levels.

The county has already reduced the speed limit on the road from 30 to 25 miles per hour, and asked local law enforcement to increase enforcement of the current 13-ton weight limit on the road. The lower speed limit will remain in place for the northbound lane.
