A recently discovered sewer cave-in has forced Louisville MSD to reduce traffic on Main Street in the midst of other repairs to the same sewer line underneath the street.

The cave-in was found when video from a remote-control camera placed into the line for inspection revealed a hole in the side of the pipe. Debris, including abandoned pipes, have fallen into the large sewer line from this hole. 

The cave-in wasn’t present when MSD last inspected this portion of the pipe on June 21.
