Fire crews are warning Canton, Massachusetts residents that a downed pole is causing heavy traffic Thursday.

According to the Canton Fire Department, the utility pole fell across Washington Street at Sullivan Way. The northbound lane is opening back up to traffic but the southbound lane remains closed and diverted.

It is unclear what caused the pole to fall, but an overnight storm did cause localized flooding across New England.

No injuries were immediately reported.

Crews are working to remove the pole.
