The Ultimate Guide to Traveling the Road SP345B

Strada Provinziale 345B (SP345B) is the name of a high mountain road located in the province of Brescia, in the northern Italian region of Lombardy. It runs almost entirely over 1.900 meters above the sea level.


Set high in the northern part of the country, the road, also known as Delle Tre Valli, is mostly paved with gravel sections, but navigable by all passenger vehicles. It’s 17.2km long running north-south from Passo di Croce Domini to Passo del Maniva. The road is narrow and challenging. To drive the road without stopping will take most people between 45 and 60 minutes.

Due its elevation, the road is usually impassable in winters. The open and close dates all depend on snowmelt and snowfall each year. The road can be travelled in both directions. The speed limit is 20 km/h. The road is totally rideable despite of the many rocks and deteriorated surface especially in curves. It’s forbidden to overtake or stopping outside the parking areas.
