The Sandö Bridge (Swedish: Sandöbron) is a concrete arch bridge crossing the Ångerman River in Kramfors Municipality in northern Sweden.

The surrounding area is often referred to as The High Coast.

During the construction, the bridge collapsed on 31 August 1939, and 18 workers were killed.

This accident was given little attention by the press, since World War II started the morning after.

In 1997, the Sandö bridge was replaced as main road connection driving north to south along the coast by the Höga Kusten Bridge, the new bridge across the river, in a new extension of the European route E4 further downstream.
