An overturned military Humvee on the New Jersey Turnpike closed the highway in both the car and truck lanes in Middlesex County creating a miles-long delay just before the start of the afternoon rush.

The accident injured at least four soldiers in the vehicle.

UPDATE: 4 Army reservists recovering after Turnpike overturned Humvee accident

New Jersey Fast Traffic said the southbound lanes reopened around 4 p.m. near Exit 8A for Jamesburg in South Brunswick.

State Police spokesman Trooper Lawrence Peale said one man was flown in critical condition to Robert Wood Johnson Hospital. Two other men and a woman were also flown to the New Brunswick hospital via medical helicopter as well. Peele did not know which branch of the military was involved in the accident nor an exact number of victims.

A spokesman for the Army Reserves at Fort Dix told MyCentralJersey.com the injured soldiers are with Army Reserves Unit 533rd Brigade Support Battalion stationed at Fort Totten in Queens, New York.

Peele said the accident occurred around 2:30 p.m. but could not identify anyone involved. The military vehicle was the only one involved.

The closure caused delays on Routes 32 and 535 as well as Routes 1 and 18 as drivers exited the Turnpike in search of an alternative route. Turnpike delays went back to at least exit #9 for Route 18.

New Jersey Fast Traffic's Bob Williams said "Get off at Exit 9 and take Route 18 or Route 1 if you can to really get around the accident." Williams said Route 130 is a good alternative to avoid the Turnpike completely as the delays filter out.
