The original road was built in 1820–25 by the
Austrian Empire to connect the former Habsburg possession of
Lombardy with Austria, covering a climb of . The engineer and project manager was (1775–1845, in 1840 knighted as
Carl Donegani von Stilfserberg). Since then, the route has changed very little. The less famous 22km long southern part has 34 rather sweeping
hairpin turns and, in the lower part near Bormio, six tunnels. The 48 mostly tight
hairpin turns on the 28 km long northern side part, numbered with stones, are a challenge to motorists.
Stirling Moss went off the road here during a vintage car event in the 1990s, with an onboard video of his incident being shown on satellite TV. Before the end of
World War I, it formed the border between the
Austro-Hungarian Empire and the
Italian Kingdom. The
Swiss had an outpost and a hotel (which was destroyed) on the
Dreisprachenspitze (literally, Three-Language-Peak, the third being
Romansh). During
World War I, fierce battles were fought in the ice and snow of the area, with gunfire even crossing the Swiss area at times. The three nations made an agreement not to fire over Swiss territory, which jutted out in between Austria (to the north) and Italy (to the south). Instead, they could fire down the pass, as Swiss territory was up and around the peak. After 1919, with the expansion of Italy, the pass lost its strategic importance. navigating the snow atop the Stelvio Pass during the
1965 Giro d'Italia The Stelvio Pass remains important for sport when it is open from May through November. Countless cyclists and motorcyclists struggle to get to the highest stretch of road in the Eastern Alps. It is the highest finish of any
Grand Tour. The
Giro d'Italia often crosses the Stelvio Pass (it was crossed by the Giro for the first time in
1953, when
Fausto Coppi beat
Hugo Koblet). As the highest peak, it has been named the
Cima Coppi in each edition. Every year, the pass is closed to motor vehicles on one day in late August when about 8,000 cyclists ride and around 25 runners run to the top of the Stelvio.
Bormio regularly hosts
World Cup ski racing, usually in late December for a men's
downhill event; its
Pista Stelvio is among the most challenging courses on the circuit. The Stelvio Pass was also picked by the British car show
Top Gear as its choice for the "greatest driving road in the world". This conclusion was reached in the first episode of the show's
10th series after the team went in search of a road that would satisfy every "petrolhead's" driving fantasies.
Top Gear later decided that the
Transfăgărășan Highway in
Romania was a superior driving road. In 2008,
Moto Guzzi started selling a
Stelvio model, named after the pass.
Alfa Romeo debuted its
Stelvio crossover SUV at the 2016 Los Angeles Motor Show. The Stelvio Pass Glacier in Italy, at an altitude of , normally permits skiing year-round, but was closed to skiing for the first time in 90 years in August 2017 due to a heatwave.
