The M25 has infiltrated British music, film, and comedy. It’s the subject of a classic Blur song (“The Great Escape” whispers about it), and it’s been mocked endlessly by comedians like Stewart Lee and the cast of The IT Crowd. If you’re a fan of British road trip movies, you’ll spot the M25 in the background of Hot Fuzz and The Trip—though usually as a punchline.
Even Prince Charles has weighed in, calling the M25 a “concrete collar” around London. It’s a phrase that stuck because, let’s face it, it’s accurate. The road is a barrier, a connector, and a national joke all rolled into one 117-mile ribbon.
Then there’s the legendary M25 traffic jam of 2011, when a stalled lorry near J14 caused a 12-mile queue that lasted six hours. It became headline news, spawning memes and a mild national panic. That day, 117 miles felt more like 1,170.
A Curious Historical Detour
Did you know the M25 was originally planned in the 1960s as a response to London’s growing traffic? It took nearly two decades to build, with the final section—the western part near the M40—opening to a chorus of relief and dread. It cost £1 billion in today’s money, which sounds like a bargain given how much time it saves or wastes.

Interestingly, the M25’s official name is the “London Orbital Motorway,” which sounds far grander than its reality. Orbital suggests a graceful loop, but in practice it’s more of a mechanical snake with a tendency to hiss and coil. And yet, without it, London would be a gridlock nightmare twenty-four hours a day.
Fun fact: if you drove the M25 at the legal maximum of 70 mph with zero traffic, you’d complete the loop in about 1 hour and 40 minutes. That’s roughly the length of a Taylor Swift concert—but with less singing and more sign-reading.
