Brenner Autobahn Brenner Autobahn The Brenner Autobahn ( or , ) refers to a major European truck route, which connects Innsbruck in Austria to Modena in northern Italy. Numbered as the A13 in the Austrian section, the motorway is relatively short and entirely located within the state of Tyrol. Upon reaching the Italy-Austria border at the Brenner Pass (), the motorway becomes A22 in Italy and runs to Modena, where it connects to the A1 motorway between Milan and Rome. It is part of the major European route E45. The historic Brenner Pass is the one of the lowest among the Central
Tyrol E45. The dual carriageway from Merano to Bolzano (MeBo) ends in Bolzano South in the Brenner motorway. Important road section in Trentino, next to the Brenner motorway, is the SS 47 (Strada Statale 47), which connects via Sugana Valley Trento with Padova. A large part of this route is dual-lane and flows into the Brenner state road (SS 12). Due to the Alps, there are many mountain passes that connect valleys. The most important pass roads for transit trade are the Reschen Pass and Brenner Pass. Popular pass roads include the Stelvio Pass, Arlberg Pass, Karer Pass, Mendel Pass and
