The Autostrada A51 in Italy is a highway near Milano featured in Euro Truck Simulator 2. It forms the eastern part of the city's orbital highway, with the A4 forming the northern side and the rest of the circle numbered A50.
There is a single toll gate on the A51 near its junction with the A4. As the tolled section interconnects with the A4 as well as the A22, a ticketing scheme is applied and the final toll depends on which other toll gate a trucker eventually arrives at. The shortest trip would be turning west on the A4 to northern Milan, with a cost of €3; while a trip to Venezia is €33.
The southern end of the highway in-game is actually part of A1 in real-life. It's possible that the game rendered the whole section as one road as the A1 section is very short.
