text: The pointed bridge over the river Bragazzo seems a one way road (NorthEast to SouthWest). If you plan a trip fromCase Mazzi(0.7 km SW) to Borgo di Terzo (1 km NE) you will notice that trip is through Via Costa-Via Chiesa (250 m north of marker) instead of proper SS42.
  By the way MapFactor Navigator doesn't find the bridge on Via Chiesa and taker a 50 km detour.
