Three fatal crashes in the North Bay, East Bay and South Bay snarled traffic Sunday morning, according to the California Highway Patrol.
All lanes of eastbound Interstate 80 at the Berkeley Curve were temporarily shut down around 9:40 a.m. following a multivehicle wreck that killed a girl, according to the CHP.
A pickup truck was traveling along the stretch of roadway when the driver lost control, spun out and slammed into the center divider before ending up in the middle of traffic, according to the CHP.
A sedan traveling in the same direction also spun out of control moments later and crashed into the truck, the CHP said.
One person in the sedan was killed in the collision and was identified later Sunday as a 10-year-old San Francisco girl, according to the Alameda County Coroner's Office. Three other people inside the sedan were taken to the hospital for precautionary reasons, the CHP said.
All eastbound lanes of Interstate 80 reopened hours after the crashes occurred.
Over in Marin County, another fatal crash blocked multiple lanes of southbound Highway 101 just north of Spencer Avenue, fire officials announced around 9:30 a.m.
All southbound lanes of the highway were reopened about two hours later, but the CHP warned about residual delays heading in the direction of San Francisco.
It is not clear what caused the crash.
In the South Bay, a Sunnyvale man died in a solo-vehicle crash about 8:05 a.m. on Highway 101 in Mountain View, CHP officials said.
The crash occurred just off the Ellis Street off-ramp from southbound 101.
A preliminary investigation indicates that a black 1995 Honda was traveling south on Highway 101 approaching the Ellis Street off-ramp when a white 2014 Honda cut in front of the other vehicle to exit at Ellis Street.
CHP officials said the driver of the black Honda tried to avoid hitting the white Honda and lost control of the vehicle.
The black Honda crashed into a perimeter fence and overturned. The Sunnyvale man, who was 29, was taken to Stanford Hospital where he died.
CHP officials said neither alcohol nor drugs appear to have played a role in the crash.
