The Romans also developed the Great St. Bernard Pass beginning in the year 47, and in 69 part of the legions of Vitellius used it to traverse the Alps. The passes were expanded from dirt trails to narrow paved roads. Between 101 and 260, the legions moved out of the region, allowing trade to expand. In Raetia, Roman culture and language became dominant. Nearly 2,000 years later, some of the population of Graubünden still speak Romansh which is descended from Vulgar Latin.
