Passo San Boldo (The Road of 100 Days / 5 Tunnel Hairpins)

Italy · SP635

An engineering marvel built by the Austro-Hungarian army in just 100 days during WWI. The southern ramp climbs a nearly vertical rock amphitheater using five interconnected loop tunnels cut into the rock face, each containing a sharp hairpin turn regulated by timed traffic lights. Exits into the rolling vineyards of the Prosecco wine hills.

Passo San Boldo (The Road of 100 Days / 5 Tunnel Hairpins) runs 11 miles between Trichiana / Belluno Valley, Italy and Tovena, Treviso (Prosecco Hills), Italy. We count about 38 corners along it, which is flowing rather than tight. Demanding, and not a road to meet in the wet.
