The construction of the road took only three months, and it served as a way of supplying the Piave front, from February to June 1918.The project belonged to the Austro-Hungarian army as part of its World War I logistical efforts. Due to its short construction period, it is nicknamed the "Road of 100 Days." It was actually build by the war prisoners, men, women and children who lived around. Despite the extreme topography, the requirement that the road shall be used for transporting heavy artillery and supplies meant that the grade could not exceed 12%.
At the end of the 19th century this road was rebuilt in order to make it motor able.
