Today we address Manchester's inner city or urban motorway, the A57M. It's probably best avoided, and to be honest with all the (bloody) trams who needs to drive anyway. It's a delight of 60s design which becomes very apparent in this video as we explore dodgy slip roads and missing carriageways. In this series I aim to explore what our motorway network is hiding. As we drive along at 70mph..ish...we simply just wouldn't be aware of what we're missing. This series will uncover some of the hidden secrets our motorways have to offer.
