A pole, wires and branches crashed down on Mamaroneck Avenue early Friday morning, closing a section of the roadway on the border of White Plains and Harrison.
Mamaroneck Avenue was closed between Union and Purdy avenues, but has since reopened.
The incident also forced the closure of the northbound Hutchinson River Parkway ramp at Exit 13A/B at Mamaroneck Avenue.
Con Edison says the pole and wires have been removed.
