Federal Highway B 503 would have crossed the extended runway in a tunnel.
The extended runways and expanded terminals, however, could not prevent a tragedy.
The extended runway was completed in 1977.
The current terminal was opened along with an extended runway in 1986, along with new underwater road tunnels to the main city of Ålesund.
In the mid-1950s the new extended runway was completed, allowing to handle larger aircraft such as Ilyushin-18 and Tupolev-104 jets.
Construction work started in May 2010, and on December 3, 2011, the extended runway was opened and put into use for the first time.
The new extended runway opened on August 12, 2007.
The airport reopened in 1963 with a new terminal and an extended runway.
