Four people had to be cut from the wreckage of two vehicles that crashed early Saturday on Interstate 95 near the Westport-Fairfield border.

Both vehicles rolled over in the collision in the highway's northbound lanes, between Exits 18 and 19, near the Sasco Creek Overpass just before 2 a.m., according to the fire report.

Firefighters from both Westport and Fairfield were dispatched to the scene.

According to fire Lt. Justin Greenhaw, who was among the first firefighters on scene in Fairfield Engine 4, there were three people trapped in one of the vehicles and one in the other. The latter individual appeared to be uninjured, while the other three had moderate to serious injuries, according to the report.

Two of the injured were transported to Bridgeport Hospital and the other was taken to Norwalk Hospital.

"This was a serious accident and a very complicated extrication," Fairfield Assistant Fire Chief George Gomola said in a statement issued after the incident. "The high level of professionalism and cooperation demonstrated by the Fairfield and Westport fire departments during this extrication helped to saved lives and reduced the impact of this accident on the victims.

"This was a job well done by all."

The last Fairfield fire unit cleared the scene about 3 a.m.
