Sinkhole returns on Raleigh's Hammond Road

It worked for a few days, until the road began to sag Thursday morning due to settling under the road. Crews then poured more asphalt.

"It sank some more, so that idea is not going to go," DOT Spokesman Steve Abbott said.

A timelapse video of the sinkhole, caused by a pipe that formed a large cavity, shows the ground sinking Thursday shortly after repairs were completed.

Crews hoped to reopen both lanes later in the day. That did not happen.

DOT officials said it would not send workers down into the sinkhole because of safety reasons. They plan to plan to dig up the problem spot and lay a more firm foundation underneath, then return in a few weeks to replace the pipe by drilling from the side of the road.

Crews will begin work on their more permanent fix on Friday. One southbound lane of Hammond Road will remain open.
