Dreadnought, also known as the 'Malago Storm Water Interceptor' or something like that was built in the early 1970s to carry flood water from the River Malago to the River Avon in Bristol.

Seeing as I ended up somewhere down south recently, it seemed rude not to pop over to Bristol and lift a manhole or two - Dreadnought didn't disappoint

Not sleeping for 72 hours took its toll, so the report is a bit anaemic compared to others - by this stage I just wanted to get in, get a few shots and bugger off back to bed! Apologies...
