A fast-moving grass fire that broke out Thursday afternoon near Livermore, California, has scorched 261.8 acres but is now reported to be 60% contained, according to the Alameda County Fire Department (ACFD). Known as the Midway Fire, it started around 2:51 p.m. near Patterson Pass Road and Midway Road, just outside of Mountain House.
As of 6:03 p.m. on Thursday, forward progress of the fire had been stopped. Initial containment efforts were quickly escalated as the fire jumped the busy Interstate 580, forcing authorities to temporarily shut down the freeway between Patterson Pass Road and I-205. Fire crews, backed by 15 engines, one helicopter, and a total of 150 personnel, worked rapidly to contain the blaze under difficult conditions. Aerial support from fire retardant air tankers across California also contributed to halting the spread.
Cal Fire and ACFD coordinated closely on the ground and from the air to prevent the fire from threatening any nearby communities or infrastructure. Despite the speed at which the fire spread in the early hours, no structures were reported to be at risk. Fortunately, no evacuation orders were issued, and there have been no reports of injuries, according to Alameda County Fire Chief Randall West.
The official cause of the Midway Fire is still under investigation. However, preliminary assessments suggest that the blaze may have originated from downed transmission lines in the area. PG&E, the local utility provider, has been notified and is currently on-site conducting a detailed investigation into whether damaged equipment played a role. Patch has reached out to PG&E for comment but has not yet received a response.
The incident highlights the ongoing vulnerability of California's dry landscapes to fire hazards, particularly in areas where power infrastructure intersects with open grasslands. Cal Fire officials have warned that with the fire season underway, residents should remain alert to local fire warnings and preparedness measures.
The fire’s location near Mountain House and Patterson Pass has made it a high-visibility event for commuters and local residents alike, as smoke and emergency activity briefly disrupted traffic and daily routines. Despite the severity of the incident, the quick response by fire crews and favorable evening weather conditions have helped keep the situation under control.
As of now, firefighting operations continue to focus on reinforcing containment lines and preventing flare-ups. Authorities will continue to monitor the situation and provide updates as new information becomes available. Residents are encouraged to stay informed via Cal Fire updates and local emergency services.
