Caltrans lane and road closures physically in place RIGHT NOW. Data: the Caltrans Lane Closure System (LCS). Only closures that crews have actually established (CHP code 1097) and not yet picked up are returned - scheduled-but-not-started closures are excluded, so this is "what is blocking lanes now", not a construction calendar. Refresh: 5-minute cache over per-district Caltrans feeds. Filters: route (e.g. "I-80", "US 101", "1"); district (Caltrans district 1-12, e.g. 3 = Sacramento/Tahoe, 4 = Bay Area, 7 = Los Angeles); center "lat,lon" with radius_km - closures whose begin or end point is inside the circle. For a town or place, center is the filter that catches work on EVERY road around it, including small state routes. Read closure_class on each record, it is what the closure means for through traffic: - "full-roadway": the road itself is closed in that direction. The only class that means "you can't drive through". - "ramp": a ramp or connector is closed (even when the raw record says "Full", that means the ramp is fully closed, not the highway). - "one-way-traffic": alternating single lane with flagging; passable with delays. Common on two-lane mountain roads. - "alternating-lanes", "moving", "traffic-break": rolling or brief work; minor delays. - "lane": some lanes closed; the lanes field says how many of how many. estimated_delay_minutes is present when crews reported one. Shoulder-only work is excluded entirely.
