It certainly looks like a vent/intervention shaft for the road tunnel. There is an emergency exit in the offside wall of each tunnel bore, roughly at the mid-point of the tunnels, just south-west of where they pass under Leamouth Road. (Look for the green signs in the tunnel on Street View.) You would expect there to be an exit portal on the empty patch of land above it, but there's nothing. So perhaps the emergency exit doors in the tunnel lead to a path just below the surface which ends at the mystery structure. Possibly there were problems obtaining access to anywhere closer. -- Richard J. (to email me, swap 'uk' and 'yon' in address) |

There are three or four of those green lights, and I strongly suspect that they just lead to the other tunnel, not the surface. |

There are in fact 3 exits per tunnel bore, numbered 1W, 2W, 3W for the eastbound bore (sic), and 1E, 2E, 3E for the westbound. (The road, which is really Aspen Way, runs generally east-west, except for this bit of tunnel which is sort-of north-south, hence the curious compass IDs.) -- Richard J.
