Caltrans Emergency Road Closures due to incidents impacts. This layer is updated from information provided by Caltrans Headquarters Communication Center in support of state emergency response efforts for 2022 incidents.
These closures represent Slides, Flooding, Slide removal, Snow, Wash Out, Wildfire, Adverse Weather, Storm/Fire Related Repairs, Road Damage, or Slip-out initiated restrictions on highway locations.
Caltrans emergency road closures data represents highway postmile segment lengths closed related to wildfire impacts and safety concerns. These road closures are identified and reported by departmental field staff, Traffic Management Centers (TMCs), and compiled by Caltrans Headquarters Communication Center in coordination and support of law enforcement and fire officials.
Caltrans statewide Highway Condition Reporting Requirements (HCRR) enable the timely notification and collection of road restriction information that includes: Caltrans district, California county, type of road restriction, geographic location, postmiles, detour if applicable, and temporal information on closure and estimated opening times.
This service will be updated as road closures are reported by Caltrans HQ Communication Center and remain supported for the duration of California statewide wildfire support and coordination efforts.
Additional information on Caltrans postmile system and road closures can be found by visiting the Caltrans Postmile Service application and the Caltrans Quickmap web application. For current highway conditions please visit Caltrans Road Information.
