California's drawbridges have no live status anywhere — they run on phone calls to the bridge tender and four hours' vessel notice. So here's every movable bridge, its federal opening rule, and where published, the tender's phone number. Rush-hour lift bans (8–9 a.m., 4:30–6:30 p.m. on the Alameda estuary) included.

No California agency publishes live drawbridge status — openings mostly require 4 hours’ advance vessel notice, so they’re rare and pre-arranged. The old Schuyler Heim lift bridge was replaced by a fixed span in 2020. Also see Seattle and the other state pages on the Maps hub.
