Two very different New Yorks: upstate, 20 Erie Canal lift bridges rise on demand all season (each with its own phone — on this map); downstate, NYC's movable bridges need two hours' notice and the Long Island parkway drawbridges lift for the boat channels. Tap any bridge 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: canal lift bridges come from the NY Canal Corporation’s own dataset (coords, phones); opening rules come from the US Coast Guard’s Drawbridge Operation Regulations (33 CFR Part 117). No New York agency publishes live raised/lowered status — canal bridges open on demand in navigation season, and NYC bridges open only with advance notice.
