Indiana drawbridge map — the lakefront spans

Indiana’s movable bridges cluster on Lake Michigan — Michigan City’s Franklin Street bridge opens seasonally for the Trail Creek marina fleet, and the Indiana Harbor Canal’s spans at East Chicago serve the steel-mill waterway. Tap any bridge for its rule.

How it works: opening rules come from the US Coast Guard’s Drawbridge Operation Regulations (33 CFR Part 117). Indiana publishes no live drawbridge status, so schedules are the tool here. Bridges without a map pin are listed with their rule but haven’t been precisely located yet. Also see Seattle and the other state pages on the Maps hub.
