‘World’s longest’ purpose-built cycling tunnel opens in Norway

April 18, 2023

A three-kilometer-long (1.8-mile) cycling and pedestrian tunnel has been blasted through the base of Løvstakken mountain and its makers say it’s the longest purpose-built tunnel of its kind.

Fyllingsdalstunnelen, as it’s known, opened on April 15 with a family day of sporting activities, following four years of construction that began in February 2019. The state-funded mega-project cost close to $29 million, or 300 million Norwegian kroner. CNN
