A cyclist was stopped by police as he was about to begin a three-kilometre incline inside the Oslofjord tunnel after following a Google Maps route into the underpass.
The cyclist was escorted out of the tunnel by police, reports newspaper VG - thelocal reports.
“We received reports of the cyclist as he approached the entrance to the tunnel and followed him with our cameras,” duty operator Stein Ekholdt at Oslo’s central traffic coordinator (Veitrafikksentralen) told VG.
“He suddenly stopped and sat down, so we closed the tunnel,” Ekholdt said.
After the tunnel was closed at 20:33 on Wednesday, police carried out a minor rescue operation, with two police officers entering the tunnel from the Buskerud side by motorcycle and two from the Follo side by car, according to the report.
“The man did not seem to have much experience in cycling long distances, and especially not up hills. He had a three-kilometre long incline ahead of him. The bicycle was an off-road cycle,” Ekholdt said.
The coordinator said that the situation in the tunnel could have become dangerous.
