Twenty minutes. That is how long it takes to drive through the Laerdal Tunnel, and the engineers who designed it understood that twenty minutes underground, in a straight tube through a mountain, could unravel a driver's composure. So they built three enormous caverns inside the mountain, spaced at six-kilometer intervals, and lit them with blue light fading to yellow at the edges to create the impression of sunrise. The caverns break the tunnel into four psychological segments, each short enough to feel manageable. They serve as turnaround points, rest areas, and antidotes to claustrophobia. At 24.51 kilometers, the Laerdal Tunnel is the longest road tunnel in the world, a distinction it has held since opening on 27 November 2000. It connects Laerdal Municipality and Aurland Municipality in Vestland county, carrying two lanes of the European Route E16 under a mountain range that would otherwise require a ferry crossing or a treacherous winter mountain road.

Norway's geography is an engineer's nightmare. Mountain ranges, deep fjords, and harsh winters have historically made overland travel between the country's major cities an exercise in patience and ferry timetables. The road between Oslo and Bergen, Norway's two largest cities, wa...

The tunnel's most innovative feature is its acknowledgment of human psychology. Long tunnels are monotonous, and monotony leads to fatigue, distraction, and accidents. The three internal caverns, each large enough to park in, use lighting designed to mimic the transition from nig...

Air quality inside a 24-kilometer tube full of car exhaust is an obvious concern, and the Laerdal Tunnel was the first in the world to address it with an air treatment plant built inside the mountain itself. Located in a 100-meter-wide cavern about 9.5 kilometers from the Aurland...

Beginning in 2025, the Laerdal Tunnel entered a years-long period of nightly closures for upgrades to comply with updated EU safety regulations. For approximately four years, the tunnel closes for fourteen hours each night, forcing drivers onto alternative routes such as Road 50,...
