NEW CANAAN -- The northbound Merritt Parkway was closed for more than an hour Wednesday afternoon after a double rollover accident just north of the Old Stamford Road exit.

At least one driver was extricated from a vehicle after the crash, but it wasn't immediately clear how badly either driver was injured.

State police, Stamford police and police and firefighters from New Canaan responded to the crash, which happened just after 12:40 p.m. and prompted both northbound lanes to be shut down.

A dispatcher at State Police Troop G in Bridgeport said that the highway was reopened at some time around 2 p.m.

No other details were immediately available.
