The Gudvanga Tunnel ( or Gudvangentunnelen) is located in the municipality of Aurland in Vestland county, Norway. The tunnel connects the village of Gudvangen, at the head of the Nærøyfjord, with the Undredalen valley and is part of European Route E16. At 11428 m in length, it is Norway's third longest road tunnel. It was opened on 17 December 1991.

Nearby tunnels

After passing through the Gudvanga Tunnel, drivers pass through a number of other tunnels. About 500 m east of the eastern exit from the Gudvanga Tunnel a new tunnel begins: the 5053 m long Flenja Tunnel which ends at Flåm. Approximately 1 km after that tunnel is the 1363 m Fretheim Tunnel. About 7 km further to the east (near Aurlandsvangen) is the entrance to the 24.5 km long Lærdal Tunnel, which is the world's longest road tunnel. This means that in a 51.5 km section of the E16, 43 km of that distance consists of tunnels.

Fires

In August 2013, a truck caught fire in the tunnel, resulting in 55 people being hospitalised. In August 2015, a tourist bus caught fire 500 m from the exit. In March 2019, a truck burned down about 1.5 km from the tunnel entry.
