Looks like those long struts are arms welcoming you along the bridge.
Tower Bridge London, UK. By Don Davis Photography.
Camera Nikon D700 with 16-35mm Nikon Lens. ISO 100, 30 second exposure, 16mm, f/16.0, Tripod Mounted. The camera was shaking every time a bus went past, so until I got home I didn’t really know how these shots would come out.
