Predil Pass, a paved road in the Julian Alps
Passo di Predil (Predel) is an international mountain pass at an elevation of 1.156m (3,793ft), located on the border between Italy and Slovenia.
Located within the Julian Alps, the road to the summit is paved, but steep, hitting a 13.1% through some of the ramps. It’’s called Strada Statale 254 in Italy and 203 in Slovenia. The pass is 7.0 km long, running from Cave del Predil (in the Province of Udine, in the Friuli-Venezia Giulia region of northeastern Italy) to Strmec na Predelu (in the Littoral region of Slovenia).
It’s a difficult road, with uncountable turns and twists. The road traversing the pass has been a major trade route since at least Roman times. In 1903, a 4.5 km (2.8 mi) long tunnel (Štoln) was built beneath the pass, serving miners from Log pod Mangartom on their way to the lead mines in Cave del Predil.
