Mississippi River Bottoms Meyers Island Access Road

Meyers Island Access Road drops off Illinois Route 100 into the Mississippi River bottomlands, where seasonal flooding creates a constantly changing maze of sloughs, oxbows, and towheads. The route follows Corps of Engineers maintenance roads built on spoil dikes, crossing three separate channels via concrete fords that disappear completely during spring floods. Your destination is 400-acre Meyers Island, accessible only when river levels drop below 15 feet at the Grafton gauge.

This is expert-level seasonal driving that demands intimate knowledge of flood cycles and river conditions. High-clearance 4WD with snorkel and recovery gear is mandatory—mud holes can swallow vehicles to the axles. Best attempted late summer through early fall when water levels stabilize. No camping allowed on Corps property, but the experience of reaching true river isolation makes the technical challenge worthwhile. Check Corps flood forecasts and carry emergency communications.
