Fyllingsdalstunnelen is a 2.9-kilometer-long bicycle and pedestrian tunnel in Bergen, Norway. It is the world’s longest tunnel built specifically for cyclists and pedestrians.

It doubles as an escape route for train passengers, with dedicated pedestrian and cycle lanes of 2.25 and 3.5 meters wide, respectively, included in its design. At 2.9km long, the tunnel takes about 10 minutes to cycle and 30 to 45 minutes to walk. Colorful dynamic lighting in the tunnel creates a wave of light when a cyclist or pedestrian enters the tunnel at either end, alerting cyclists to oncoming traffic.

The tunnel was opened in April 2023 and is part of a larger project to improve the transportation infrastructure in Bergen. The project also includes the construction of a new road tunnel and a light rail line.

Fyllingsdalstunnelen is well-lit and has a smooth surface, making it a safe and comfortable way to travel. The tunnel is also a major environmental initiative. It is expected to reduce traffic congestion and improve air quality in Bergen.
