An overnight crash Tuesday that closed all lanes on the southbound side of Route 9 in Manalapan has resulted in two deaths, officials have confirmed.

The crash occurred just after 2 a.m. north of Craig Road, according to the New Jersey Department of Transportation. "Please be advised that the members of the Monmouth County Prosecutor’s Office, Monmouth County Serious Collision Analysis Response Team and the Manalapan Police Department are investigating a motor-vehicle crash on Route 9 from early this morning that resulted in two fatalities," the Monmouth County prosecutor's Office said in a statement. "The investigation is ongoing at this time."

At least one vehicle could be seen on the roadway with extensive damage as multiple first responders worked to investigate the crash and clear debris from the roadway.

The crash prompted police to close the southbound lanes to traffic for a few hours. The northbound lanes remained open, but traffic was moving slowly through the area early Tuesday morning.

Police have not yet released any information on the crash victims.
