Passo San Boldo (South side)
Passo San Boldo is a small mountain pass in Veneto between the towns of Trichiana and Tovena in the Cison di Valmarino region. 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 (2,316 ft). The mountain pass is called the SP 635 and only one lane is passable, the traffic is regulated by several sets of lights. 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. There are five tunnels blasted into the rock with hairpin turns or loops, and six bridges. Although the need to rebuild the steep road over the San Boldo pass into a motorable road was clear by the end of the 19th century, this project languished until the Austro-Hungarian army accomplished it from February to June 1918 as part of its World War I logistical efforts. The road to supply the Piave front was built in only three months. Due to its short construction period, it is nicknamed the ’Road of 100 Days’.
