Two exits on Highway 15 will be closed for the next three weeks.

As of 10 p.m. Sunday July 15, the exit for Wellington St. will be off-limits to drivers heading north and south.

Drivers heading north will have to detour via Exit 61 (Atwater), then loop around via St. Patrick and re-enter the highway heading south, only to exit at Atwater again to reach Wellington St.

The other alternative is to get off at Exit 57 for Highway 10.

The exit closures are scheduled to last until August 7.
