With a total of 313 km of highway track, A22 originates near Modena, at the interchange on motorway A1, not far from Modena-Nord toll booth. After Modena, the motorway traverses the whole Pianura Padana, overshooting Carpi and Mantua, in the real Po Valley heart. In Verona A22 crosses highway A4, afterwards it settles in the Adige Valley, in parallel to Lake Garda. It goes past Rovereto, then passing through Trento and Bolzano. From here, it sets inside the Isarco Valley (known in German as 'Eisacktal'), tighter than Po and Adige valleys. Therefore, here A22 twists and turns through the valley, easily overtaking Bressanone and then going over Vipiteno toll booth. Finally, A22 reaches the Brenner Pass in Brennero, where it gets the Austrian border and comes to its end. Here, the passageway Modena-Munich goes on crossing the boundary, following the Austrian A13 Brenner Autobahn. As it clearly appears, A22 is a strongly important highway for connections and transports between Southern and Northern Europe, designed on a track studied and planned to make use of one of the lowest mountain passes in the Alps, the Brenner Pass - one of the busiest borders in Europe - located at only 1375 m above sea level.
