The three-car crash closed down all lanes of the span, which connects Bayonne with Staten Island, for the entire Friday morning commute. The bridge reopened around 11 a.m..
Port Authority police say the suspect was initially driving a Staten Island-bound burgundy Ford van that crossed the median on the bridge and crashed head-on into a New Jersey-bound Volkswagon Passat.
When a Good Samaritan from Staten Island stopped and got out of his black Dodge 1500 pickup to offer assistance, the driver of the Ford van stole the pickup truck and sped off.
The driver and passenger in the Volkswagon were taken by ambulance to Richmond University Medical Center on Staten Island with serious but non-life threatening injuries.
A female passenger suffered lacerations to her head, while the male driver sustained lacerations to his left arm.
The suspect is described only as a man about 5-foot-6. The getaway vehicle was found abandoned on Staten Island.
No arrests have been made.
