A major intersection in Downtown Niles remained closed Thursday morning nearly 24 hours after water gushed through the pavement.

Although the 24-inch water main has been repaired, a boil alert has been issued following a water main break at North Main Street and Park Avenue in front of the McKinley Memorial Library.

The alert affects water customers on Main St. from Robbins to the Viaduct; State St. from Robbins to Main; Arlington, Chestnut, Church, and East Park from State to Main.

Street department barricades remain along North Main Street, forcing drivers to take a detour around the downtown area.
