This evening, Awwrisp and I did a trip through the Holbeck culvert in Leeds. It's probably been done before, but I've been unable to find any details anywhere.
It's just one long culvert, I've measured it roughly on a map and from start to finish, in a straight line it is just under one and a half miles. We were in there just about one hour.
The inlet photographs were taken a couple of weekends ago. On tonights trip, my camera started playing up. This turned out to be user error, which got sorted when we got out, so there is only one photo of inside from me.
The inlet;
Just inside, on the right, is a branch tunnel of the same size as the main tunnel. I suspect it brings in the water from the stream which flows past the portal of the Gildersome tunnel. We didn't explore this branch.
A couple of hundred yards in, the square culvert changes to a round culvert, the water flow is faster and is a bit slippy, but this section only lasts about 50 yards. Apart from an interesting side tunnel, which contains some filtering equipment, thats about it. Awwrisp took some pictures of the filtering equipment on his phone, so maybe he will post them.
My one internal shot;
The outlet;
After the outlet, a nice open culvert led down to the River Aire;
The very short final bit where it joins the Aire;
Finally, thanks to Awwrisp for his company.
