We are standing by the westbound ramp from the A6 Downing Street onto the Mancunian Way. The Mancunian Way street sign has been mounted on the railings upside down. It's probably the work of a local prankster. The newly installed sign beyond it indicates that this is the A57(M), with the motorway symbol. Like many urban motorways, this one has a speed limit of 50 mph.
