A woman walking on the shoulder of Interstate 5 suddenly crossed the freeway and was struck by an oncoming car Wednesday.
California Highway Patrol officers said the woman was killed on impact and thrown hundreds of feet from the point of the collision.
The incident occurred just after 9 p.m. and involved a silver Honda SUV traveling on northbound I-5 near Old Town, south of Interstate 8.
The Honda driver was taken to a nearby hospital with minor injuries, CHP officers said.
Northbound I-5 was closed for a while during the investigation.
CHP officers said with the number of homeless people living along this stretch of I-5, they are seeing more incidents of people walking on the interstate.
The victim's identity was not released.
