Another great post, with photos, on Caroline's Miscellany. 

While Greenwich and Woolwich have pedestrian foot tunnels, nearby Rotherhithe is generally thought of as a tunnel for motorists. In fact, there is pedestrian access as well, with a pavement provided on each side of the roadway. In the interests of tunnel completeness, I decided to take a walk inside.
