San Boldo Pass is a very peculiar pass and climb. The mountain pass is only one lane and the traffic is regulated by several sets of lights. There are five tunnels blasted into the rock with hairpin turns or loops, and six bridges. There is a speed limit of 30 km/h and a height limit of 3.2 m, after buses were repeatedly stuck in the tunnel. This small mountain pass in Veneto connects the towns Trichiana and Tovena in the Cison di Valmarino region over a distance of 17 km. The pass lies at the southern edge of the Alps and connects the Val Belluna with the Val Mareno over a height of 706 m.
