Hairpin Highway, Austria



A hairpin turn (also hairpin bend, hairpin corner, etc.), named for its resemblance to a hairpin/bobby pin, is a bend in a road with a very acute inner angle, making it necessary for an oncoming vehicle to turn almost 180° to continue on the road. Such turns in ramps and trails may be called switchbacks in American English, by analogy with switchback railways. In British English 'switchback' is more likely to refer to a heavily undulating road—a use extended from the rollercoaster and the other type of switchback railway.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[citation needed] hairpin turns, 48 of them on the northern side numbered with stones, are a challenge to motorists.
