This scenic byway offers 33 miles of majestic views that include soaring limestone bluffs and quaint towns such as Grafton and Alton that lead to the confluence of the Mississippi, Illinois and Missouri rivers.

See how you size up against the life-size bronze statue of Robert Wadlow, the world's tallest man (at nearly nine feet) and an Alton native. Learn more about Wadlow at the Alton Museum of History & Art across the street, which displays mementos from the “Gentle Giant,” including family photos and his oversized grade school ring.
