The North Entrance to Dover's Napoleonic defences embedded into the Western Heights consists of two bridge/drawbridge combinations and a 60-yard long road tunnel.
Only the ribs of the bridges are left and the tunnel, whose surface is made from wooden blocks to prevent sparks, is blocked at both ends.
This video is in two parts, Part 2 can be seen at:
Part 1 has opening scenes of Dover Castle and the Drop Redoubt and then moves to a shot of where the original North Military Road ('Military Hill') diverges from the bypass that now cuts through the moats.
The next sequence is taken at the closed end of the tunnel and gives information about the underground water reservoirs, the 'roundabout', and various other features.
The road tunnel is then traced out on the surface and a shot shown (from above) of the vertical beams of the drawbridge.
The final sequences are of a Second World War (World War Two) pillbox overlooking the two bridges, except you can't see them because of the vegetation!
The photograph mentioned in the commentary of the inside of the road tunnel is at:
UPDATE: In the commentary, I infer the steel cables above the road tunnel were used to operate the drawbridge. In fact, they are anti-submarine nets, but I've no idea at the moment what they are doing there.

Dover is in the county of Kent in England (UK).
