ROCKLAND — The Maine Department of Transportation is trying to figure out what to do about a 65-foot deep sinkhole in the town of Rockland.

On Monday the transportation department used radar, which can detect hollowness in the road, to find other possible sinkhole sites.

Mike Burns, the transportation department’s acting bureau director of maintenance and operations, told the Bangor Daily news that he hopes to have a plan to fix the road in the next two weeks.

The 25-foot-wide sinkhole opened on County Road in about 90 minutes a week ago.
