Alton to Evansville: Road Trip Guide for the Wabash River Valley

The drive from Alton, Illinois to Evansville, Indiana covers roughly 225 miles along the Great River Road (IL-100) and Interstate 64, a route that follows the historic traces of the Wabash and Ohio Rivers. This journey spans three states—Illinois, Missouri (a brief dip near the start), and Indiana—and passes through landscapes shaped by glaciers, rivers, and 19th-century canal dreams.

One little-known fact: near the halfway point, the route crosses the old alignment of the Wabash and Erie Canal, once the longest canal in the United States. Today, fragments of the canal are preserved in state parks and local museums. Understanding this history enriches the journey, transforming a simple highway cruise into a search for hidden stories.
