RAMONA, Calif. — A deadly crash near Ramona Monday prompted crews to close State Route 67 in both directions for several hours, officials said.

According to the California Highway Patrol, the crash happened around 3:40 a.m. on SR-67 near Boortz Lane when two vehicles hit each other head-on.

CHP said in an update Tuesday that a 23-year-old man was driving a Volkswagen Jetta northbound on SR-67 when he drove over the painted double yellow lines into the southbound lane for reasons still under investigation.

The Volkswagen then collided head-on with a Toyota Camry being driven by a 20-year-old woman, according to CHP Public Information Officer Jared Grieshaber.

The driver of the Volkswagen was pronounced dead at the scene of the crash, CHP said. The driver of the Toyota was taken to Palomar Medical Center with non-life-threatening injuries.

Debris was scattered over the freeway lanes in both directions, prompting a Sig-Alert to be issued around 4:30 a.m. for all lanes of SR-67.

SR-67 was closed in both directions for nearly four hours as Caltrans crews worked to clear the roadway.

The identity of the man who was killed in the crash has not yet been publicly released and CHP has not yet determined if drugs or alcohol were a factor in the crash.
