A water line broke after a contractor installing new poles on Farmington Avenue in Bristol damaged it, according to the Bristol Water Department.
Crews are at the site and will be excavating the road to repair the water main leak.
The break only affects water at one property, but traffic could be delayed as crews work on repairs, the water department said.
Drivers should be able to get by in both directions, but lanes might reduced from two to one.
The water department advises motorists to seek alternate route to avoid delays and thanks its customers for their patience.
