A break in a 12-inch water main is expected to be repaired by Friday morning, a spokesperson from Missouri American Water said.

The break, which happened near the intersection of Lemay Ferry and Will Avenue across the street from Mehlville High School, happened at around 5 p.m. Thursday.

Crews were on the scene shortly after the break, and a spokesman said they will be working into the night to complete the repair. They did not say if any users were out of service.
