The 71-year-old Bonita woman who died in an Interstate 8 traffic accident Tuesday morning was heading to Kansas to visit family.
According to county Deputy Coroner Rick Williams, the woman, Betty June Austin, was headed east for the Midwest with her husband, James Mervin Austin, 66, when a truck tractor pulling a pair of dirt and gravel trailers jackknifed across the length of I-8 near the Fourth Street off-ramp.
The Austin's vehicle, a pickup, slammed into the axle connecting the first trailer with the tractor.
Williams said an ambulance was called at 8:28 a.m. He said the Austins were both wearing seat belts.
Betty June Austin, who had been in the passenger seat, was pronounced dead at 8:50 a.m.
Lee Havens, the owner of the rig, said, "This is very rare. We haven't had an accident in several years."
Havens said the truck was coming from an Ocotillo gravel pit on its way to El Centro.
