Sarp Bridge

About

Sarp Bridge (Norwegian: Sarpsbrua or Sarpebrua) is a group of bridges which cross Sarpefossen, a waterfall of the river Glomma in Sarpsborg, Norway. One bridge carries a pathway, one carries a single track of the Østfold Line and one carries two lanes of National Road 118. The road and pathway bridges are about 91 meters (299 ft) long, while the railway bridge is 247 meters (810 ft).

The first bridge at the site was a brick suspension bridge opened on 25 February 1854. It was rebuilt as a multilayer bridge and opened with rail tracks on an upper truss level on 2 January 1879. In order to strengthen the railway, a new steel truss railway bridge opened on 9 May 1931. The former bridge was then rebuilt as a wider road bridge. An accident on 15 April 1940 caused the fire department to blow away one of the pillars, collapsing the superstructure. A new road bridge was completed in 1943. The two were supplemented with a separate pathway bridge in 1977. There are plans to replace the existing bridges with a four-lane road and three-track railway bridge, scheduled for no later than 2030.
