UPDATE SATURDAY: Interstate 5 through the Grapevine north of Los Angeles was reopened Friday night, Caltrans said. Highway 58 near Tehachapi remains closed due to mudslides.
Segments of Highway 101 throughout San Luis Obispo County are experiencing heavy traffic Friday due to closures of portions of Interstate 5 and Highway 58.
According to the California Highway Patrol, I-5 near Fort Tejon, commonly known as the Grapevine, and Highway 58 near Tehachapi in Kern County were closed late Thursday afternoon because of flooding and mudslides from recent rains.
Caltrans is reporting that a steady flow of traffic, including big-rig commercial trucks, are re-routing through San Luis Obispo County via Highway 41 and Highway 46 onto Highway 101.
A CHP spokeswoman said Friday morning that one lane of northbound I-5 is expected to open through the Grapevine by noon, which could relieve some congestion, but southbound I-5 is not expected until early evening.
Segments of Highway 101, including at the Cuesta Grade, were moving slowly Friday morning, according to the CHP.
Transit officials say the flooding is affecting traffic throughout San Luis Obispo, Santa Barbara, Monterey and Santa Cruz counties and are asking motorists to plan appropriately and slow down while in commute.
