The border between Norway and Russia consists of a 195.7-kilometer (121.6 mi) land border between Sør-Varanger, Norway, and Pechengsky District, Russia, and a 23.2-kilometer (14.4 mi) marine border in the Varangerfjord. It further consists of a border between the two countries' exclusive economic zones (EEZ) in the Barents Sea and the Arctic Ocean. Between 1944 and 1991 the border was between Norway and the Soviet Union. There is a single border crossing, on E105, located at Storskog in Norway and Borisoglebsky in Russia. The Norwegian side is patrolled by the Garrison of Sør-Varanger and is under the jurisdiction of the Norwegian Border Commissioner, while the Russian side is patrolled by the Border Guard Service of Russia. Two-thirds of the border follows two rivers, the Pasvikelva and Jakobselva.
