Highway 166 Reopens After Six-Day Closure

Six days after the outbreak of the fire, Highway 166 has been reopened for travelers, providing relief for those commuting within the Central Coast and Cuyama Valley. Nevertheless, Caltrans has asked all motorists to proceed with caution owing to the presence of active firefighting crews and smoke visibility within the corridor.

As of July 9, 2025, the fire has been contained up to 62%, up from 35% on July 8. Firefighters have marshaled 1,450 personnel, supported by several tankers, water tenders, helicopters, and fire engines.

As per reports, almost 50 structures were threatened by the fire. One building was destroyed during the fire, and one firefighter sustained injuries. Evacuation orders and warnings were issued across the county. However, they have now been eased.

While substantial progress has been made in the containment of the Madre Fire, visible smoke and hot spots remain. Authorities have continued to issue air quality warnings, even urging sensitive groups to limit exposure to the outdoors.
