Colle di Costa Piana is a high mountain pass at an elevation of 2.313m (7,588ft) above the sea level, located in the Province of Turin, Italy.
The pass, also known as Colle Cotte Plain, is traversed by the Assietta Road (officially called Strada provinciale 173 del Colle dell'Assietta), a military carriageway along the ridge that gathers Pian dell’Alpe to Sestriere. When the road is open there are several rules: the speed limit of 48.3 mph/30kph (30 km/h) from Sestriere to Pian dell’Alpe; the prohibition to overtake and to stop out of parking’ zone and the prohibition of vehicles transit over 35 tons.
This gravel road just opens from June 1st to October 31st. It’s rideable despite of the many rocks and deteriorated surface especially in curves. This is one of many passes on the spectacular Assietta ridge road from Susa to Sestriere in the western Italian Alps.
