This is the big daddy of tunnels on the GAP. It is long , has no lights and is cool as hell (oxymoron intended). What a job to tackle with the equipment available when they built it. Unlike the other tunnels this one is not for trains but for canal boats and the animals the pulled them through. There is only room for the waterway and a path above it for the mules/horses.
As I was walking thru it I wondered what kind of lights were used in the day and what happened when there was 2 way traffic.
When you get a handle on what the builders had to overcome it is amazing . The need to get stuff from one side of the mountains drove the builders to get the job done. Again, this is a place that you have to see to appreciate . Once again I felt tremendously lucky to be able t5ake all this in.
This is loooking back at a biker we met in the tunnel making his way out the other end. Actually we met several bikers while in the tunnel and it was eerie seeing the little lights coming closer and closer.
