NASHVILLE, Tenn. -
Metro Public Works crews spent Wednesday morning repairing a sinkhole on 5th Avenue South in downtown Nashville.
The sinkhole, an estimated five feet in diameter and three feet deep, opened overnight between Korean Veterans Boulevard and Peabody Street.
An area parking lot attendee first noticed the road sinking Tuesday night. The sinkhole had formed by the time the attendee returned to work Wednesday morning.
Officials blocked off part of 5th Avenue South around the hole and began making repairs.
"Most often it's because there's a leak in the pipe and we have some underground erosion, that's usually what the problem is," said Mark Macy, chief engineer at Metro Public Works.
Macy said there's a storm water pipe below the surface and Metro Water will be checking to make sure it is sealed up tight.
There is the possibility that construction on the new Music City Center and the nearby Omni Hotel could have weakened the road.
"There was a lot of work and even work done in that specific area and that's one of the possible problems that maybe when they built the manholes and the pipes they didn't get it compacted correctly and that's one reason we have settlements in certain places," said Macy.
Workers filled the sinkhole and put a metal plate on top of it, allowing the concrete to harden for a few days.
