Knapps Narrows at Tilghman Island opens about 10,800 times a year — the busiest drawbridge in the country, on demand, around the clock. Kent Narrows runs a seasonal hour/half-hour schedule; Annapolis’ Spa Creek bridge holds shut through rush hours. Every Maryland movable bridge — tap for its rule.
MileCheck shows live DOT alerts, mile markers, and bridges on the road — in all 50 states, with CarPlay and Android Auto.
App Store Google PlayHow it works: opening rules come from the US Coast Guard’s Drawbridge Operation Regulations (33 CFR Part 117), cross-checked against MDOT SHA’s movable-bridges list. Maryland publishes no live status — Knapps Narrows’ tenders still keep paper logs — so schedules and phone/VHF are the tools here. Also see Seattle and the other state pages on the Maps hub.
