Traffic is flowing again southbound on I-95 in Bridgeport after it was shut down a week ago because of a fiery crash.
Chris Cooper, spokesman for the state Department of Transportation, said the three lanes were opened about 3:30 a.m.
Television coverage showed traffic moving slowly along the roadway in a light rain.
Crews had worked Tuesday and throughout the night to pave over a section of temporary bridge brought in to replace the overpass.
It was destroyed last Thursday night after the accident in which a tanker truck carrying heating oil struck a concrete barrier and burst into flames.
The northbound lanes of the bridge were repaired and reopened Sunday night.
