Some history of Pass di Stelvio
History
The original road was built in 1820-25 by the Austrian Empire to connect the former Austrian province of Lombardia with the rest of Austria, covering a climb of 1871 m. The engineer and project manager was Carlo Donegani (1775–1845). Since then, the route has changed very little. Its sixty hairpin turns, 48 of them on the northern side 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. During World War I, fierce battles were fought in the ice and snow of the area, with gun fire 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.
The Stelvio Pass retains an importance for sport when it is open from June to September. 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 Coppi beat Koblet). The last winner on the pass was Thomas De Gendt in 2012. Every year, the pass is closed to motor vehicles on one day in late August when about 8000 cyclists ride on the Stelvio.

Bormio regularly hosts World Cup ski racing; its Pista Stelvio is among the most challenging men's downhill courses on the circuit.
The Stelvio Pass was also picked by the British automotive show Top Gear as its choice for the "greatest driving road in the world", although their search was concentrated only in Europe. This conclusion was reached after the team went in search of a road that would satisfy every "petrolhead's" driving fantasies in the premiere of the show's 10th season. Top Gear later decided that the Transfăgărăşan Highway in Romania was possibly a superior driving road.
In 2008, Moto Guzzi started selling a Stelvio model, named after the famous mountain pass.
Today the Stelvio Pass is visited by many motorists attracted by the exhilarating drive and many event organizers choose the pass as a way-point driving through Switzerland to Italy, such as The Great Rally
