One person died early Saturday and another suffered major injuries in a single-vehicle accident on northbound Highway 99 in Modesto, authorities said.
The wreck occurred just south of Kansas Avenue and forced the California Highway Patrol to close the middle and right lanes of the highway at 5:20 a.m. for a few hours.
CHP Sgt. John O'Neil said Saturday night that the driver was speeding and making lane changes and lost control. Information on the driver was being withheld pending notification of family.
O'Neil said the passenger is from Modesto.
