Springfield, IL to Decorah, IA: A Road Trip Guide

The drive from Springfield, Illinois to Decorah, Iowa covers roughly 330 miles along a corridor that traces the Mississippi River's western flank. A little-known fact: just north of Springfield, the road passes through the site of the 1812 New Madrid earthquake's farthest-reaching tremors, which briefly reversed the flow of the Mississippi. This trip straddles the transition from Illinois's flat farmland to Iowa's rolling Driftless Area, a region untouched by the last glaciers.

Highways involved include I-72 west from Springfield to US-67 north, then US-20 west into Iowa. Total driving time is about 5.5 hours without stops, but the route is rich with attractions.
