"Gamle Fossumbru" (Old Fossumbru) refers to the original bridge that spanned the Glomma River between Askim and Spydeberg, Norway, before it was replaced by the Fossumbru in 1961. The original bridge, a wooden arch structure, was partially destroyed during the Battle of Fossum Bridge during the Nazi invasion of Norway in 1940. The new Fossumbru, a suspension structure with a main span of 125 metres, is now the bridge that crosses the river at that location.

Nice gravel road with short but very steep climb to a bridge. Halfway is a small bakery/farmshop.
