The three-vehicle collision between a red pickup truck, a silver sedan and another vehicle was reported at 7:39 a.m. near Treasure Island, CHP officials said.
Three eastbound lanes were initially blocked. Two lanes reopened as of 8:24 a.m. and one lane will remain closed because of a previously planned Caltrans closure, according to the CHP.
An ambulance was called because at least one person involved in the crash suffered minor injuries.
