    Hello Folks,

    I've recently spoken to a crane driver who has for many years carried out piling works around the UK, especially the lower reaches of the River Thames, my conversation with this gentleman entered onto 'tunnels beneath the Thames'.

    He described the many Thames side sites that he has worked on, often driving 28 metre piles into the ground.

    Leading on from our conversation, he told me that either side of the current Dartford Tunnels there were subsidiary tunnels bored and blocked-off at each end. He stated that these were bored to be used as emergency/subsidiary tunnels in case the existing tunnel became inoperative for whatever reason.

    Quite honestly, I find this a little hard to believe, especially knowing the congestion in those road tunnels when the QEII bridge is closed due to high winds or exceptionally inclement weather. Wouldn't those lost and never-ued tunnels be brought into use?

    Fiction or reality - do please comment - I personally know nothing further.

    Does anyone on this list know better??

    I, like you, find this a little hard to believe, to one side of the tunnels is littlebrook power station, and the fuel holding tanks, and latterly the humungous distribution depot that has been built. On the other side are the foundations for the bridge if nothing else, along with the gravel pit on the essex side, and the ships fuel terminal.

    given the collosal cost of tunnelling (that's why a bridge was built instead of another tunnel), it just wouldn't make any sense to construct a redundant tunnel.

    Over the years, I've had a few mooches around this area, along the river wall on the Dartford side, and I've never seen anything which would remotely suggest this to be the case.

    Also, there is no space for the infrastructure to support it (approach roads etc), the local authority would surely have prevented the development of the areas if there was a potential for the land being required.

    ready to be corrected....

    Thank you for taking the time to respond to my snippet. I entirely agree with what you say, doubtless another fantasy.

    Hi, I also agree with you guys and find it a little hard to believe but my dad works around in that area as a lorry driver and one day as we was going through the tunnel there was something going on and we was in gridlock traffic throughout and then we had these to workman come down the tunnel and on our left hand side there was these two doors and they opened them for some reason and we could see the lights on the other side and in fact it was a secondary tunnel with a few steps but I think they use these for maintenance work. So I would say that man is telling the truth but I wouldn't suggest going there because they only seem to be accessible from the inside and they could be in regular use. :thumb

    I believe what you were seeing was the second Dartford Tunnel. One is primarily used for motorists. The secondary one is used for dangerous goods (you'll often see fuel tankers awaiting escort when approaching the tunnel) and in the event the Bridge is closed for whatever reason. The tunnels are interlinked at regular intervals, so if there is ever an incident in the first tunnel, motorists can evacuate via the second. Trivia: my father worked on the second Dartford Tunnel.

    maybe this:

    The Dartford Cable Tunnel is a £11,000,000 tunnel upstream of the Dartford Crossing built in 2003-4. Its diameter is ~3m. It is designed to carry and allow for maintenance of 380kV National Grid electrical cable beneath the Thames; it is accessible by foot as a crossing of the Thames, but by authorised personnel only

    Yeh, theres load of cable tunnels around there. The Dartford one on your map there is quite modern, about 10 yrears old. It runs from Littlebrook to the old West Thurrock site. Pops up just the other side of the substation to where the station used to be easy to spot on google maps. To be honest i dont think it would be that interesting as its just a modern tunnel. However ive never quite been able to work out what else might be left on the thurrock site. theres cirtanly potential to be somthing good there. The main offices/frontage from the station are still there but they built a little chemical works on the site of the turbine/boilerhouse so im guessing they were re-used some how. That said there may well be a nice 60s powerstation control room under lock and key in there somewhere, who knows!

    As for the Dartford tunnel i dont think there is a service tunnel for that but there might be. I think theres just the two main bores.
