Spanning 15.2 miles long, the Lærdal Tunnel is the longest of its kind in the whole world.
Located in Norway, the impressive structure stretches from Lærdal to Aurland and links Oslo to Bergen.
The road tunnel opened back in November 2000 after five years of construction and cost a whopping 1.08 billion Norwegian kroner (£80k/$107k) to build.
And it has a particularly special design that makes driving through the tunnel a unique experience.
Every 3.73 miles the road widens into a cave area adorned with colourful lighting, a contrast from the white lights that run down the tunnel.
Drivers can park up in these rock chambers and take a break while enjoying the yellow and blue hues.
It takes 20 minutes to drive the full length of the tunnel, if vehicle users are travelling at the 80km/h speed limit.
The road burrows underneath a mountain range, only adding to the impressive experience.

The Lærdal Tunnel is seen as one of the safest in the world, according to National Geographic.
It has a range of impressive features including a state-of-the-art ventilation system that purifies the air.
There are 15 cameras along the road keeping tabs on any accidents.
If something does occur, they are able to trigger an automated system that closes the tunnel to help manage the situation.
The tunnel even has emergency equipment including fire extinguishers and phones on hand at dedicated safety spots every 500 metres for if something goes wrong.
It has become quite an attraction, and has hundreds of reviews on Google, with one driver writing, ‘It was a nice experience to go through world’s longest tunnel, 24.5 km.
‘After every 6 km there are blue lights to give some relief to eyes. It took us about 18 minutes to cross each way. Worth seeing…’
Another penned: ‘I recently drove through the Lærdalstunnelen, and it was an impressive experience! The tunnel is incredibly long — over 24 kilometers — yet it felt safe and comfortable to drive.

‘What really stands out are the beautifully designed lighted sections along the way, which break up the drive and create a unique atmosphere.
‘The colourful lighting not only adds visual interest but also helps keep drivers alert on such a long stretch. A remarkable piece of engineering and a must-experience when driving in Norway!’
Elsewhere, the Gotthard Base Tunnel in Switzerland takes the crown for the longest tunnel in the world.
It is only used by trains and spans 35.4 miles long.
