The May 4 fire broke out on the San Mateo-Hayward bridge while nurse Neriza Fojas, who was among those killed, was celebrating her recent wedding with a group of friends. Four other friends and the limo driver survived.
Authorities reviewed video and photos of the fire, and interviewed survivors, including driver Orville Brown, who has said he helped survivors escape through a partition blocking the passenger area.
The CHP says it will release the results of its investigation, and recordings of 911 calls, Monday afternoon.
