Norway. In the winter, bad weather and snow storms can cause the road to be temporarily closed, though, unlike many minor roads, it is kept open wherever practical. Because the road is the main artery through the country, cyclists and leisure travellers avoid the southern sections owing to the excessive traffic. In the north traffic is sparse. History and future plans This road was called E6 in the old "E" road system before 1975 and previously continued to Rome (introduced in Sweden 1962 and in Norway 1965). It was given the number E47 (but not signposted) in the new system on most of the Scandinavian part (Helsingborg–Olderfjord), and E6 only for the northernmost (from Olderfjord in Finnmark). After a political negotiation, the whole part passing through Scandinavia was given the number E6 in the new system, introduced in Scandinavia in 1992. The part Trelleborg-Helsingborg was never intended to be part of E47. E47 connects to E4 at the Helsingør-Helsingborg ferry, and E4 and E6 connect just outside Helsingborg. The E6 became 4-lane motorway all the way from Trelleborg to Kolomoen (near Hamar) in 2015, although the road is sometimes wider. The new Svinesund Bridge opened in 2005, replacing an earlier and narrower bridge from 1946. In 2012-2018 the road was shortened by 39 km between Narvik and Alta, by building the Hålogaland Bridge and more bridges and tunnels. 60 kilometre road between Moelv and Øyer is under conversion to 4-lane motorway, set to be finished around 2025. In Trøndelag, several sections north and south of Trondheim are under construction, or planned as motorways, this project is planned to be 106 kilometers long and it will go from the junction with Norwegian National Road 3 at Ulsberg in the south to Åsen north of Trondheim Airport, Værnes, set to be finished in 2027/2028, it will be financed by the state owned company Nye Veier. On 8 June 2022, a damaged fairly short bridge (at Badderen), that gave a 163 km detour between Tromsø and Alta, got a temporary bridge installed (over the damaged bridge) after a week interruption.
