Norra_länken
Norra länken (The northern link) is a motorway in Stockholm, Sweden, between the port of Värtahamnen and Karlberg, where it connects to Essingeleden. The road is part of the European route E20 and the incomplete Stockholm Ring Road.[1]
Norra länken is 5 kilometers (3 mi) in length, 4 km (2.5 mi) of which are in tunnels.[2] The part between Karlberg and Norrtull was opened in 1991, and the tunnel between Norrtull and Värtan was opened in 2014. The other parts of the ring road are the highly congested Essingeleden in the west, opened in 1966, Södra länken in the south, opened in 2004, and Österleden in the east, where (as of September 2017[update]) plans have been canceled.[3]
