Brenner Autobahn Eastern Alps; this favourable location was therefore suitable for building the first motorway crossing among the Alpine main chains. Unlike other higher passes across the Alps, the Brenner Pass remains open all-year round and through the winter months. Construction of the motorway began in 1959 and the "Brenner Autobahn", including the Bridge of Europe (Europe's highest motorway bridge then), was partially open in 1963. The A13 begins in the south of Innsbruck from the east-west motorway A12 Inntal Autobahn ("Inn Valley Motorway"), which links Bregenz in western Austria to Kufstein near the border of Bavaria in Germany.

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
