I'm going to start my third 365 Project on 1st April (no, it's not an April Fool!) but I couldn't resist catching this as I was up in London today.
These works have featured in the "Impossible Engineering" TV documentary series. They are related to the new infrastructure being created for the London Crossrail project (Google it for more info!).
Later note: I've re-posted this shot to a previous album so thanks for any comments that may have been deleted as a result - no need for any further comments!
