LOUISVILLE (WHAS) -- Several streets downtown will be closed indefinitely due to an MSD sewer collapse. A section of the roadway caved-in due to a collapsed, 102-inch concrete sewer pipe installed in 1948.

MSD has secured the area. Excavation and repairs are expected to occur after this weekend's forecasted rainfall. Repairs will take several weeks.

"It's something we've been monitoring all the time. We've been knowing it need to have work done on it, but we didn't have the money to invest in that. We did not expect it to get this bad this quickly, so in the last few years it has had a major turn for the bad," said MSD Chief of Operations, Brian Bingham.

The closures will be on East Main Street between Jackson and South Clay Street and Hancock Street between East Market Street and East Washington Street, an intersection near Slugger Field on the East side of the interstate.

The entrance to Louisville Slugger Field's parking lot at Main Street and South Jackson Street remain open.
