How Long Is The Dartford Tunnel

Ever found yourself cruising down the M25, wondering just how long that Dartford Tunnel is? You're not alone. This iconic stretch of road is a rite of passage for any Brit, and that tunnel? It's a bit of a mystery. Let's dive in.

So, How Long Is It?

The Dartford Tunnel, officially known as the Dartford River Crossing, is a pair of tunnels that run under the River Thames. The western tunnel, built in 1963, is 1,665 metres long. The eastern tunnel, opened in 1980, is slightly longer at 1,680 metres. That's about a mile and a half each, or roughly the length of 15 double-decker buses parked end to end.

But here's a fun fact: the eastern tunnel is actually a bit too long. When it was built, they accidentally made it 15 metres longer than planned. Oops!

Why Two Tunnels?

You might be wondering, why two tunnels? Well, back in the '60s, the river was a major barrier to traffic. The first tunnel was built to ease congestion. But by the '70s, traffic was already building up again. So, they decided to build another tunnel. It's like having a backup plan for your backup plan.

And speaking of plans, did you know that the tunnel was originally going to be a bridge? But the government decided that a tunnel would be less of an eyesore. So, the bridge idea was scrapped. Literally.

Tunnel Trivia

Ever noticed the strange symbols on the tunnel walls? They're called fiducial marks, and they help drivers stay in the middle of the lane. Clever, huh?

And here's a bit of culture for you: the tunnel has made appearances in movies like The Sweeney and Skyfall. Plus, it's been the setting for some iconic music videos, like Spaceman by Babylon Zoo and Virtual Insanity by Jamiroquai.

Reflections
