A 73-year-old Lakeport man was pronounced dead Tuesday after crashing his sedan into a big rig at Petrified Forest Road near Franz Valley School Road, according to the California Highway Patrol. 

The man, identified as John Michael Norin, was heading westbound on Petrified Forest Road just before noon when he drove his vehicle across solid double-yellow lines and crashed head-on into a tractor-trailer heading eastbound, officials said.

Norin was transported via CHP helicopter to Santa Rose Memorial Hospital, where he died of his injuries. 

The driver of the big rig, Howard Beeman III of Inverness, was not injured, the CHP said. 

The roads were blocked for about 2 1/2 hours.
