South Tyrol One of the most important highways is the A22, also called the "Autostrada del Brennero". It connects to the Brenner Autobahn in Austria. The vehicle registration plate of South Tyrol is the two-letter provincial code Bz for the capital city, Bolzano. Along with the autonomous Trentino (Tn) and Aosta Valley (Ao), South Tyrol is allowed to surmount its license plates with its coat of arms. Rail transport goes over the Brenner Pass. The Brenner Railway is a major line connecting the Austrian and Italian railways from Innsbruck and Verona climbing the Wipptal, passing over the Brenner Pass and descending down
Brenner Pass Raetia. Via Augusta was completed in 46–47 AD; the route took its course along the Adige valley to the neighbouring Reschen Pass (west of Brenner Pass at above ), then descended into the Inn valley before rising to Fern Pass towards Augsburg. The Roman road that physically crossed over Brenner Pass did not exist until the 2nd century AD. It took the "eastern" route through the Puster Valley and descended into Veldidena (modern-day Wilten), where it crossed the Inn and into Zirl and arrived at Augsburg via Garmisch-Partenkirchen. The Alamanni (Germanic tribe) crossed the Brenner Pass southward into modern-day Italy
