Milan to Clermont-Ferrand: Ultimate Road Trip Guide

The A4 motorway east of Milan was originally laid out in 1927, making it one of Italy's earliest autostradas. Today, that same corridor connects Milan to Turin, then leads into the Fréjus Tunnel and the French A43. The full drive to Clermont-Ferrand spans roughly 580 kilometers (360 miles) and typically takes 6 to 7 hours without extended stops. This route crosses the Alps via the Fréjus Tunnel, a 12.9-kilometer engineering marvel that opened in 1980.
