Before he got to the ferry, Mr Monkey noticed this little building, which claimed to be a foot tunnel. He checked, and the sign was right, so he took the lift down and scampered under the Thames. It wasn't really that different from going through the Greenwich Foot Tunnel, apart from being in Woolwich.
There's a page about the Woolwich Foot tunnel at the Structurea website, with some pictures that Mr Rik sent them.
