Mackinac Island MI to Nashville IN Road Trip Guide

Mackinac Island, Michigan, famously bans motor vehicles, yet your road trip begins just off its shores in St. Ignace or Mackinaw City. The drive to Nashville, Indiana covers roughly 450 miles, taking 7-8 hours without stops. The route traverses the geologic boundary of the Mackinac Straits, where Lake Michigan meets Lake Huron, and follows US-127 south before cutting across the Indiana border to IN-135.

One historical oddity: the Mackinac Bridge, opened in 1957, is the world's longest suspension bridge between anchorages at 8,614 feet. Crossing it provides your first dose of vertical drama.
