Umbrail Pass

Umbrail Pass is a high mountain pass on the Italy–Switzerland border, connecting Santa Maria in Val Müstair with Bormio in the Adda valley. On the Italian side, it connects to the Stelvio Pass road and the Valtellina. It is currently the highest paved road in Switzerland.
The sign at the top of the pass gives its elevation as above sea level, but the reference level for Swiss elevation measurements has changed since the sign was erected, leaving as the correct value according to current elevation.
The pass is named after the "Piz Umbrail", a nearby mountain peak.

History

The pass, which in medieval times was the primary route through the region, was initially known as the Stelvio Pass, Juga Rætica, or mons Braulius. It was formerly used to connect Tyrol with Lake Como, which allowed a link between the Habsburg domains in the County of Tyrol and those in the Duchy of Milan; this role was superseded by the modern Stelvio Pass which opened in 1820. In 1901, the modern road was built, and automobile transit began in 1925.
The road has been entirely asphalted since 2015. The last unpaved section was a 1.5 km stretch on the Swiss side, running between elevations of. During the 2017 Giro d'Italia, Umbrail Pass was reached during the stage from Rovetta to Bormio.
