Independence to Quad Cities: Missouri to Illinois Road Trip Guide

The route from Independence, MO to Quad Cities, IL follows I-35 N and I-80 E for approximately 350 miles.

Driving time is about 5.5 to 6 hours without stops. The route passes through rolling farmlands, small county seats, and the fringes of the Des Moines metropolitan area.

In Iowa, the terrain is mostly agricultural—corn and soybean fields. The only notable elevation change is the Loess Hills in western Iowa (visible near Missouri Valley), but this route bypasses them. The Quad Cities area marks the Mississippi River valley, with bluffs and river views.
