California drawbridge map — the Delta, the Bay, and the phones

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.

How it works: opening rules come from the US Coast Guard’s Drawbridge Operation Regulations (33 CFR Part 117); bridge-tender phone numbers from the operating agencies (SF Public Works, City of Petaluma). 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.
