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 data is updated on schedule twice daily at 0900 and 1600 through 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.For GIS related inquiries of this data, please contact Caltrans HQ Division of Maintenance GIS
