Sandesund Bridge was opened in 1978. It leads the traffic on the E6 past Sarpsborg. Under the bridge is a narrow pedestrian bridge over Glomma.
In 2005, a duplicate of the old bridge began its work, and the new bridge parallel to the old one was opened in May 2008. The old bridge was subsequently closed for renovation. It opened again in November 2008, creating a four-lane motorway.
