## Bicycle and pedestrian

Most of the tunnels listed were built for other purposes, and have not been redesigned. The Fyllingsdalentunnelen is one example of a tunnel built to purpose from the start.
The tunnels listed here can be either be pure cycling tunnels and/or pedestrian tunnels with separate tubes, or shared-use tunnels (i.e. having a shared lane, or a bike lane and footpath without a non-crossable physical separation).
