Had my eye on these for a while.
River Limy at Rawtenstall..
A smaller culvert, a small gap, then onto a bigger one .
Not very big , about 175Metres in Length with the smaller one around 20Metres.
The smaller one (red bricked ) has the old fire station above it, whereas the larger one (stone) has houses and roads above, then finally near the inlet.. a garage/Spar.
not much feature wise apart from a manhole cover, a pipe, a mongy nest with 3 eggs and a rotting chick, a small waterfall and the usual culvert arachnids.
Glad to finally get this done
