The tunnel opened in spring 2023 and is the world's longest purpose-built cycling tunnel, at 2.9 kilometres (1.8 mi) long. It runs parallel to the Bergen Light Rail tunnel through the same mountain, for which it also functions as an escape tunnel.

The width of the pathway is 6 metres (20 ft). 3.5 m (11 ft) is a bidirectional cycle lane with white asphalt, while the remaining 2.5 m (8.2 ft) is a footpath raised on a kerb.

The tunnel walls are made of slanted concrete blocks to dampen reverberation and echoes.

The tunnel is camera monitored, and has emergency lights and telephones. Cellphone coverage and emergency network has been established, as well as access for emergency vehicles.
