European route E10 is the second shortest Class A road which is part of the International E-road network. It begins in Å, Norway and ends in Luleå, Sweden. The road is about 850 km (530 mi) in length. The Norwegian part of the road is also named Kong Olav Vs vei (King Olav V's road).
The road follows the route Å - Leknes - Svolvær - Gullesfjordbotn - Evenes - Bjerkvik - Kiruna - Töre - Luleå.Most of the road is paved and two-lane, with the exception of some bridges between islands in Nordland. It has a 90- speed limit in Sweden,[1] and is usually 7-8 meters wide, enough to make encounters between heavy vehicles trouble-free. In Norway the road is much more twisting than in Sweden, and around 6–7,5 m wide usually with a speed limit of 800NaN0. New sections have been built 7.50NaN0 wide in the last 15 years, but there are still many narrow parts left. Often, the 60NaN0 width makes encounters between heavy vehicles tight. For the last 50 km, until Å, the road is mostly less than 6m (20feet) wide, often 5m (16feet). Buses and caravans should avoid driving here, but many of them do so anyway.
The name E10 was given in 1992. Before 1985, E10 was the name of the road Paris-Brussels-Amsterdam-Groningen. The road between Narvik and Kiruna was finished in 1984, before that, no road existed at all directly between the two cities; the only way to travel between them was by train (with passenger services only three times a day), or by a large detour through Finland. In 2007, the road near Lofoten was shortened by about 30 km, and the ferry-service was bypassed for the E10, with the opening of Lofast, a new road between Fiskebøl and Gullesfjordbotn. At the end of 2007, the E10 had 18 tunnels totalling 20.41NaN1, all in Norway.
