All but one lane of southbound State Route 163 was closed just south of Friars Road after a motorcycle crash Thursday evening.
The two-car crash left a motorcyclist with a major injury to his leg at about 5:30 p.m. He was taken to the hospital, according to the California Highway Patrol.
Officials issued a Sig Alert at about 6 p.m., and the alert was lifted about 30 minutes later. They said traffic is backing up to the I-15 and SR-163 split.
It's unclear how the crash happened.
