We stumbled across this one by accident after a bit of a disappointing explore the previous week, and as it seems nobody else has done this we've decided to name it Hulton Culvert because its on the Hulton familys land and they most likely built it.
The culvert is built in four sections (that are accessible from the outfall side), starting with a very tight stone arch section then opens up to a 3'-ish brick arch. The third and highest (and shortest) section is a 4'-ish brick square section/stone slab roof which quickly drops back down to 3'.
It runs underneath the old Bolton to Leigh railway, we're not sure how long it is but its a good few hundred metres. We also don't yet know where the infall is because the culvert is blocked by a collapsed left wall that has let the roof slabs fall.
....and before anyone says anything, thats not me in the wussy dust mask, thats my mate who is scared of eating a spider!
