BAYONNE - (AP) - Police are looking for a motorist who drove off in a Good Samaritan's pickup after a head-on crash that closed a major bridge in the New York metropolitan for nearly seven hours.

Port Authority police spokesman Al Della Fave says a sports utility vehicle crossed the center line and hit a car on the Bayonne Bridge around 4 a.m. Friday.

Della Fave says the driver of the SUV jumped into the pickup after a 64-year-old Staten Island, N.Y., man stopped to help.

The vehicle was found abandoned in Staten Island. There's been no sign of the driver.

Della Fave says a 27-year-old man and a 32-year-old woman from Forked River in the car suffered serious lacerations.

The Bayonne Bridge connects Bayonne with Staten Island, N.Y.
