Another highway into Tyrol through the Vintschgau came to be known as the Via Claudia Augusta, which name was also improperly applied to a portion of the Brenner Road. After much contention we think it is now generally accepted that Mommsen, who has investigated and weighed the evidence with astonishing care, is correct in assuming that the only portion of the road via the Reschen-Scheideck Pass which should be called the Via Claudia Augusta is that traversing the Vintschgau Valley. The road was constructed not in the reign of Augustus, who initiated the Brenner Road, but in that of his grandson, the Emperor Claudius, about A.D. 46-47. It was intended to connect up the River Po with the River Danube by the Reschen-Scheideck route, and along it at various times since the middle of the sixteenth century milestones of Roman origin have been discovered. Though from the fact that little reference is made to it by the better-known Roman writers of the period, one may assume that the Via Claudia was of quite secondary importance to the Brenner Road. But nevertheless it seems probable that it was the route used for the transportation of stores for the Roman forces of occupation during the fifth century not long prior to the evacuation of the country. The Brenner Road for a considerable period after its construction appears to have been rather a highway for commerce than a military road in the usual sense of the term. The chief article exported from Tyrol was salt from the still famous salt mines at Hall, near Innsbruck, on the northern bank of the Inn. There were also sent southward into Italy raw hides, timber, Alpine herbs used in the preparation of medicines, liqueurs, and the purposes of the toilet; and dairy produce of various kinds, of which cheese was probably (according to Pliny) one of the chief articles. In those far-off days, too, much excellent wine was grown far further north in Tyrol than nowadays when the vine is not cultivated, for vintage purposes at all events, further north than the southern slope of the Brenner. In Roman times the Brenner also formed a link between Aquileia, one of the most flourishing and important seaport cities on the Adriatic, and Noricum. As did also another, then important but nowadays almost deserted route, that of the Plöcken Pass, of which it is believed Cæsar made frequent use. Along this several important stations were founded, amongst them Tricesimum, Julium Carnicum (Zuglio), Aguntum (Innichen), Lonicum (Lienz) and Sebatum (Schabs). Time, however, was destined to divert the trade from the Plöcken Pass route to that of the Brenner, and the settlements along the former gradually declined in importance.
