Passage suspended over A55 was visited by urban explorers who vowed never to return

Urban explorers have revealed spooky images from inside a hidden passage that hangs over one of North Wales' busiest spots. This passage is tucked under the main railway track that crosses the A55[1] expressway and is just metres away from the Rainbow Bridge in Old Colwyn. The overpass was opened in 1983, and while many of us have driven past it, these photos show that people have ventured inside the secret passage beneath the bridge.

The explorers entered the bridge through a "heavy steel lidded manhole" and descended steel steps to try and cross to the other side. One explorer, who wished to remain anonymous, described having to "squeeze and crouch, and at one point scrape along our bellies", feeling a growing sense of claustrophobia. They said that looking down through narrow gaps onto the motorway below strangely helped keep them calm.

However, this calmness changed dramatically when they reached the halfway point and saw objects in the distance at the far end. They decided to continue further.

The explorer added: "We reached the end, and let me tell you, We have never felt the same sense of dread before or since." They were met with a single fold-away chair positioned facing a wall.

One said: "On the wall was a partially torn page from a newspaper, or a magazine, showing a fully naked lady in an erotic position. I can't put my finger on it but it seemed more sinister than sexy, if that makes any sense. The scene that lay before us had rendered us completely speechless, and an overpowering sense of panic could be felt collectively.

"Needless to say we got out of tunnel, as fast as humanly possible, smashing our knees and shins against the sharp cement edges, that lined the path to the ladder by which we had entered.

"Of course, we were all praying to God that the man-hole hadn't been re-sealed, as it was impossible to tell until you reached the ladder itself.

Thankfully the exit route was clear, and we promptly dashed as far away as our legs could carry us."

We do not recommend anyone attempts to explore the tunnel themselves.
