A frantic underwater rescue effort is underway after a tractor-trailer cab went off the Delaware Memorial Bridge and plunged into the Delaware River.
The truck crashed through a concrete barrier as it traveled southbound and plunged into the water at around 3.40 am, on Friday.
The truck that went off the bridge is a Bobtail Tractor but had no trailer attached.
It was unclear how many people were in the cab, which was found in about 20 feet of water at around 10 am, according to the Delaware River Bay and Authority.
No other vehicles were involved in the incident, but officials have not revealed any information about the driver.
The left southbound lane of the bridge is closed due to the crash.
The truck, which was heading into Delaware, crossed three lanes of traffic before striking the barrier and going into the river early Friday morning, according to the river authority.
Two four-lane spans make up the bridge that connects Delaware and New Jersey.
Rescue crews and dive teams from several agencies, including the U.S. Coast Guard, were involved in the search for the cab.
The cause of the crash is under investigation. Police have video evidence of the moment the vehicle went into the river, but so far they have not shared it.
