Bivio - Access to the Septimer and Julier Alpine Passes Bivio (German, and officially Stalla until 1902, Romansh Beiva). It lies at the foot of the Julier and Septimer Alpine Passes. Bivio is, along with Tarvisio and Luwin, the only officially Italian-speaking village north of the Alpine watershed and is considered the one in Switzerland with the greatest linguistic diversity. Bivio is located in the middle of one of Switzerland's most beautiful holiday regions: at 1,769 metres, with direct access to the Septimer and Julier Alpine Passes. Historic paths lead through the highest village in Surses – here the Romans already transported their goods. Today, holidaymakers enjoy the Alpine landscape in summer with its magnificent views, healthy climate and the play of colours of rich green and colourful flora. In addition, there are diverse opportunities for families and other guests. After all, Bivio is located in the middle of Parc Ela, Switzerland's largest nature park. This is appreciated by children eager for experiences and bike holidaymakers just as much as by all those who find relaxation on extensive hikes in the Alps.

Bivio at 1769 m above sea level. The name Bivio means “fork in the road” and is inextricably linked with the two Roman passes, Septimer and Julier. The village of 260 inhabitants probably has the strangest linguistic situation in all of Europe, so judges a prominent scholar about Bivio, the highest village in Surses.

Julier Pass, History (Pass height 2284 m above sea level) The column remnants exactly at the summit of the Julier Pass and the finds of Roman coins nearby point to a very early use of this Alpine crossing. The Septimer Pass, a few kilometers to the west, which was however steeper and more avalanche-prone, can certainly be considered a competitor. What is certain is that both were used intensively in Roman times. The Julier even with two-wheeled carts. In the age of packhorse trains, the Julier increasingly lost importance because the topography at the Septimer Pass was hardly a factor and, moreover, the detour via the Engadin was not necessary. With the construction of a cart track over the Septimer (1387), the Julier was definitively left behind. The Julier remained important for access to the Upper Engadin and the Bernina Pass. The actual road construction over the Julier took place between 1820 and 1826. In this phase of history, the Julier retained "the upper hand" over the Septimer. On the one hand, topographical reasons were decisive, and on the other hand, the canton could not afford to ignore the Engadin. This was the first road construction project in which the canton acted as the client. In the second half of the 19th century, various route adjustments followed, which became necessary due to the increasing feeder traffic for the Upper Engadin health resorts. The opening of the Albula Line of the Rhaetian Railway in 1903 caused car traffic over the Julier to collapse again. When the Federal Council put pressure on the Graubünden government in 1923 for a car-suitable transit route, the canton opted for the Julier route. Between 1935 and 1940, the pass road was renovated and was the first Alpine crossing to receive an asphalt surface. Today, the Julier is the most important, year-round open, northern access to the Engadin.

Already in the Roman Empire around 2,000 years ago Already in the Roman Empire around 2,000 years ago, the Julier Pass was of great importance. At the pass summit, two columns of a Roman sanctuary still stand today. Today, the pass road over the Julier is the most important road connection to the Engadin and is passable all year round. In the vicinity of the Julier, you will find numerous hiking and biking routes on which the landscape can be ideally explored. From the Julierhospitz (pass summit 2284 m above sea level), the exploration tour or hike to the clear mountain lake Leg Grevasalvas begins.

Julierpass, History (Pass height 2284 m above sea level) The column remnants exactly at the summit of the Julier Pass and, next to them, the finds of Roman coins point to a very early use of this Alpine crossing. The Septimer Pass, located a few kilometers to the west, which was however steeper and more avalanche-prone, can probably be considered a competitor. What is certain is that both were intensively used in Roman times. The Julier even with two-wheeled carts. In the age of packhorse trains, the Julier lost more and more importance because the topography at the Septimer Pass hardly mattered and, moreover, the detour via the Engadin was not necessary. With the construction of a small road at the Septimer (1387), the Julier finally fell behind. The Julier remained important for access to the Oberengadin and the Bernina Pass. The actual road construction at the Julier took place between 1820 and 1826. In this phase of history, the Julier retained "the upper hand" over the Septimer.
