The Great North Road was originally constructed in WW2 as a vehicle tunnel that would travel much of the length of the rock, it led onto Fosse Way which is still used by the military and has a strict no photography rule.
The entrance is at Maida Vale, the outside road names at intersections are mirrored on many inside parts as well. It [the road way] travels all the way down to Calpe Hole Generating Station, a big underground power station. Smaller pedestrian tunnels allow a route up to the Great Siege Tunnels which date back to the 18th Century.
Much of the spoil created during its construction was used for land reclamation in extending the (now) Gibraltar International Airport runway.
The GNR is no longer used bar for access, training and water transportation along a big pipe that occasionally scares the crap out of you.

but a recent development has meant that hot air is sent up the shaft causing it to be impassible and potentially effecting the atmosphere in the rest of the system.
