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
