The road is a mix of Italian autostrade, Swiss motorways, and German autobahns, each with unique rules. The E35 from Rome to Milan, then E35/E533 through the Gotthard Tunnel, and finally A1/A3 into Mainz. Expect tolls in Italy and Switzerland (vignette required). The fastest route avoids the Gotthard Tunnel in summer due to traffic; consider the A26 via Simplon Pass instead.

Road quality is excellent throughout. Italian autostrade are well-maintained but have heavy traffic near cities. Swiss motorways are pristine; German autobahns have unlimited speed sections but also no hard shoulders in some areas. Fatigue management: plan stops every 2-3 hours.
