SOUTH ST. LOUIS (KMOV.com) -

A street collapse has closed lanes of Broadway just south of downtown St. Louis.

The collapse occurred Monday afternoon near the intersection of Chouteau and Broadway. Authorities believe a sewer line, which was built in in the 1890s collapsed, causing the pavement to sink. MSD thinks a small leak in the line that grew bigger during Monday's rain.

"The pin-prick hole just washes away a little bit more soil each and every time, over time, and what you get is a small void underneath the roadway that just start to sink gradually over time," said Lance LeComb.

MSD said it had to create a big hole in the street in order to make repairs, but added that sewer line leaks themselves do not cause leaks.

"When they do happen, it is a very gradual process, it's not like a sinkhole that swallows a house in Florida," LeComb says.
