Why is there a recurring depression on North Kerr Avenue at McClelland Drive?

Ken Little

There has been a settlement issue for several years on North Kerr Avenue at McClelland Drive, and no cause has been identified yet, N.C. Department of Transportation spokeswoman Tammy Stewart said.

“New Hanover County is prone to sinkholes which develop (and) they can shift, which may be causing the depression to migrate,” Stewart said.

N.C. DOT performed a review of the area to identify storm water deficiencies and found none, Stewart said.

“Additionally, we have excavated the area and have found no voids under the pavement. The Cape Fear Public Utility Authority has a sanitary sewer line under the pavement structure for which they have performed a video inspection and have found no deficiencies,” Stewart said.

CFPUA also excavated around its manhole and found no voids.

The depression started on the southbound side of the roadway and progressed to the northbound side over time, Stewart said.

N.C. DOT continues to monitor the roadway “with regard to structure and ride quality, and takes the necessary corrective action when warranted.”

A Transportation Improvement Program slated to begin in a few years will include the intersection.

“When the TIP project nears and the department begins their geotechnical study, we will be requesting a more intensive study of that particular area,” Stewart said.
