Regional decision desk
This corridor is built around movement: trains crossing a swing bridge, tow traffic entering locks, and hundreds of thousands of cranes concentrating along a narrow river valley. The useful question is usually what is moving, where, and when.

Rail traffic and Mississippi tow movements collide at one unusual swing bridge. The live page is most useful when you want to know what reaches the bridge next.
See Fort Madison now →Approaching tows, lock operations, river conditions and visitor timing belong in one view when the trip is specifically about seeing the lock work.
Check Melvin Price →The spring pulse is survey-driven rather than continuous. The tool distinguishes official counts from modeled between-survey movement.
Check crane migration →Regional tools
The strongest tools here are not generic maps. They combine several live systems into a visitor decision that is otherwise hard to answer.
Fort Madison · Iowa
Track identified trains, named Mississippi tows, Amtrak Southwest Chief timing, river stage and predicted swing-bridge interactions.
Best for: railfans, river watchers and visitors deciding whether there is something worth seeing at the bridge soon.
USACE LPMS + NOAA/NWPS + Amtrak + licensed rail observations
Open Fort Madison LiveAlton · Illinois
See current lock activity, approaching tows, nearby vessels, Mississippi River conditions, weather and visitor-tour timing.
Best for: visitors deciding when the lock will actually be active rather than simply arriving during open hours.
USACE LPMS + CWMS stage/flow + AIS + NWS + museum schedules
Open Melvin Price LiveCentral Platte River · Nebraska
Start with official survey counts, then use labeled between-survey modeling, river conditions, flight weather and public viewing guidance.
Best for: birders and travelers choosing when within the migration season to make a long-distance trip.
Crane Trust + USGS + NOAA/NWS + historical migration climatology

Unlike a single-event destination, this corridor can generate useful traffic throughout the year because river infrastructure and migration operate on different calendars.
