Bloomington-Normal to Port Huron: Road Trip Guide

The route from Bloomington-Normal, IL to Port Huron, MI carries a piece of automotive history: it roughly traces the old National Road (US-40) through Indiana and Ohio, a path that predates the interstate system by a century. This 420-mile journey takes you from the prairie heartland to the shores of Lake Huron.

Driving time is approximately 6.5 hours without stops, but the journey's worth extends far beyond the asphalt. You'll cross three states and a time zone, passing through landscapes that shift from flat farmland to rolling hills and finally to the Great Lakes.
