Strada Provinziale 345B is a high mountain road located in the province of Brescia, in Lombardy, Italy. The road is 17.4 km long and the surface is gravel, but with high drop offs unprotected by guardrails. It runs almost entirely over 1.900 meters above the sea level.
This short gravel road, in some places only wide enough for one vehicle, and in many places bordered by a drop of hundreds of meters (many hundreds of feet) is unprotected by guardrails. Words can’t describe the road and pictures don’t do it justice. The road over the pass, also known as Delle Tre Valli, starts off the Anfo ridge road, in Passo del Maniva, and ends in the junction with the SP 669 road. The road still remains an adrenaline-pumping journey and is definitely not for the faint of lungs, heart, or legs.
The road can be travelled in the two ways. The speed limit is 20 km/h. The road starts and ends asphalted, but the middle section is graveled. Due its unique location and the climb in elevation over thousands of feet, and passing through remote areas, it is important when driving in these conditions to be prepared.
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.
