Secrets Of The Motorways

We're on a journey up the M1 to discover what lies beneath, or to the side perhaps... hidden motorway junctions, abandoned structures, ghost roads and lots more awaits.

Welcome back to another episode of Secrets of the Motorway. Today we look at the M11 that runs from Woodford in London to Girton near Cambridge. What secrets will we uncover on this 55 mile journey... secret junctions, forgotten service stations, ghost slip roads and abandoned motorways, it's all going on.
