Trieste to Positano Road Trip: Ultimate Guide to Italy's Coast

The drive from Trieste to Positano covers about 850 km along the A1 and A3/E45, taking roughly 8 to 9 hours without stops. This route crosses the entire Italian peninsula, from the Adriatic coast of Friuli-Venezia Giulia to the Tyrrhenian coast of Campania, passing through seven regions. One peculiar fact: the section near the Apennines includes a stretch of the A1 that was built in the 1960s with original tunnels that still lack emergency lanes—a detail that surprises many drivers.
