Route 53 in Danbury was closed in both directions for several hours after a car slid into a utility pole Thursday evening.
According to police, the road was shut down between South Road and Shelterock Road.
Connecticut Light & Power crews deenergized the circuit to start making repairs to the damaged pole and switched most affected customers to a different line in an effort to restore their power as soon as possible.
More than 1,000 people were without power just after the crash, but all power was restored by 9:30 p.m., according to CL&P.
Police said no one was injured in the crash.
