Dunn’s Bridge & the Great Marsh

A bridge built from World’s Fair steel, a vanished marsh the size of a million acres, and the cranes that still come back.

North Jasper County was once part of the Grand Kankakee Marsh, nearly a million acres of wetland. Legend says Dunn's Bridge over the Kankakee River was built from steel connected to the 1893 Chicago World's Fair and its original Ferris Wheel.

A half-day loop: Wheatfield, the Prairie Border preserve, Dunn's Bridge, and the Jasper-Pulaski crane platform at sunset. About 45 miles of driving from Rensselaer. Best mid-October to early December for cranes.

Play safe: stay on public sidewalks and grounds, respect private property, and never read your phone while driving.
