The City of Cranbrook says crews are working to repair the line and get water flowing through the industrial area as quickly as possible.
The City says there was a water leak along Industrial Road 2 Thursday morning.
This has forced the closure of the road from 6th Street North to Industrial Road A.
Drivers are asked to respect signage in place and to detour around the area.
Water service will be interrupted in the area while crews work to repair the line.
Once service has resumed, some customers may have dirty tap water, but it should turn clear again after running your cold taps for a minute or two.
