List of tunnels in the United Kingdom

Downhill Railway Tunnels near Castlerock on the NIR network.

This is a list of road, railway, waterway, and other tunnels in the United Kingdom.

A tunnel is an underground passageway with no defined minimum length, though it may be considered to be at least twice as long as wide. Some civic planners define a tunnel as 0.1 miles (160 m) in length or longer.

A tunnel may be for pedestrians or cyclists, for general road traffic, for motor vehicles only, for rail traffic, or for a canal. Some are aqueducts, constructed purely for carrying water—for consumption, for hydroelectric purposes or as sewers—while others carry other services such as telecommunications cables. There are even tunnels designed as wildlife crossings for European badgers and other endangered species.

The longest tunnel in the United Kingdom is the Northern line at 27,800 metres (91,200 ft). Standedge Tunnel at 5,029 metres (3.125 mi) is the longest canal tunnel in the United Kingdom.
