All southbound lanes of Highway 101 are shut down at this time at the Interstate 80 split in San Francisco due to a fiery crash involving an overturned big-rig truck, authorities said.
The crash happened near the westbound Interstate 80 split to southbound Highway 101 shortly after 5 a.m., when a truck crashed and overturned, causing a fire, the California Highway Patrol said.
Several other cars are involved in the incident, and debris from the collision fell from the freeway onto 16th Street, causing one Muni line to take detours, authorities said.
The driver of the truck suffered moderate injuries and was taken to San Francisco General Hospital.
All southbound lanes of Highway 101 are closed indefinitely. The CHP has issued a Sigalert and is urging motorists to use alternate routes.
