Sinkhole will take days to fill

It will take the D.C. Department of Transportation three more days to fill a gaping sinkhole downtown, in what one official calls one of the most complex street repairs in the past decade.

The sinkhole, located at 14th and F streets, is expected to be filled in by Friday, according to DC Water General Manager George Hawkins. Officials originally believed the hole was caused by a piece of concrete breaking a sewer line. But Hawkins said a preliminary investigation reveals a manhole blocked the sewer drain and caused rainwater to flow into the ground under the road. The excess water eroded the dirt underneath the street, which caused a piece of concrete to fall onto the sewer line.
