Creepy images have been discovered showing the inside passage that’s suspended in broad daylight over a busy dual carriageway.
The photographs were captured by urban explorers and reveal the overpass that runs across the congested road.
The tunnel lies beneath the main railway line which crosses the expressway, and lies metres away from the Rainbow Bridge, according to North Wales Live.
Reports suggest the tunnel was opened in 1983 and, while thousands of us have driven past while on the A55 road near Colwyn Bay, the eerie images show that people have been inside the concealed passage that runs underneath the bridge.
Explorers said they gained access to the bridge through a “heavy steel lidded manhole” and climbed down steel steps. They then tried to cross to the other side.
One person, who asked to remain anonymous, said they had to “squeeze and crouch, and at one point scrape along our bellies”. The person also described “a growing sense of claustrophobia” between the group.
The explorer said: “The distance from one end to the other is surprisingly long, but by the halfway point you can look down through narrow gaps onto the motorway below, which helped keep us calm in a strange way.”
But that was “about to change dramatically” when they reached the halfway point. They could see objects in the distance at the far end so they carried on further.
The person added: “We reached the end, and let me tell you, we have never felt the same sense of dread before or since. In front of us was a single fold-away chair positioned facing a wall.
“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.”
