Ten minutes after T1 exit, you can be on the A4
From Il Caravaggio International Airport’s T1, it’s about a 5–10 minute drive in light traffic to reach the A4 Motorway access, according to regular renters who time it from the parking lots. The airport sits right next to the A4 corridor, so you’re quickly pointed toward Milan, Brescia, Verona, or Venice without having to cross Bergamo city.
The A4 Motorway Access from BGY is via clearly signed ramps marked “A4 Milano/Venezia” a few hundred meters beyond the rental car exit. A Google reviewer reports reaching the A4 toward Milan in “about 10 minutes” from the rental car park, which lines up with real-world drive times in off-peak hours.
Expect tolls on the A4 itself, with the first toll booths appearing not far from the Bergamo junction in both directions. Prices vary by distance, so a short hop to Milan costs less than pushing on past Brescia or toward Venice; you’ll need cash, a bank card, or Telepass to clear the booths without slowing everyone behind you.
Traffic is the wildcard: locals say the A4 near Bergamo clogs heavily at weekday rush hours around 07:30–09:00 and 17:00–19:30, and reviews mention Friday evenings and holiday getaways doubling normal drive times. Even if you hit the on‑ramp in 8 minutes, your actual time to Milan or the lakes can swing a lot.
Regular drivers suggest opening Google Maps or Waze while still parked at T1 and checking the A4 traffic layer; if the stretch around Bergamo junction is solid red, they sometimes route via local roads for the first 5–10 km before rejoining the motorway. Some renters also snap photos of the signs from the rental car exit to the slip road so they don’t miss the “A4 Milano/Venezia” turn in the tangle of airport access lanes.
Watch out for confusing lane splits near the Bergamo junction and airport exit, especially when traffic is dense and you’re trying to read Italian signage at 90 km/h. A few reviewers mention last‑second lane changes here, so slow a bit before the junction and get into the Milano or Venezia lane early. One practical tip: program “A4 Bergamo” into your GPS before leaving T1 so the nav prompts match the signs you’ll see on the ground.
