Tunnel. Tunnel (64 wallpapers)

Tunnel - a horizontal or inclined underground structure, one of the dimensions of which is much larger than the other two.

The tunnel can be pedestrian and / or bicycle, for the movement of cars or trains, trams, moving water, laying urban networks, etc. There are also so-called ecological tunnels. They are laid under roads or railways and serve to ensure that animals can move around safely.

The main part of the metro is also laid in the form of tunnels. To avoid intersections, metro lines are laid at different depths.

Tunnels are built to overcome natural obstacles, to shorten the path, to reduce travel time. Tunnels under water barriers are often built instead of bridges where bridges would interfere with the passage of ships. Tunnels are also built to avoid crossing traffic flows at the same level. In some cases, passages under spans of bridges are also called tunnels, which, however, is incorrect.
