The Sandö Bridge spans the Ångerman river just south of Kramfors with a single 264-metre concrete arch that, in its day, was the longest of its kind in the world. The roadway sits 40 metres above the water — high enough to clear the masts of the largest cargo ships that once carried timber down the river to the Bothnian Sea.
The bridge is best seen from the western shore at Lunde, where there is a small museum to the 1931 Ådalen shootings within walking distance. The combination of bridge, river, and forested hillsides is the iconic image of the Ådalen valley.
