Secret Life of the Motorway, a BBC documentary on the UK's motorway network. The first programme, the Honeymoon Period, focuses on the golden age of motorways, which contributed to the democratisation of Britain and meant ordinary families could explore the UK as never before. The narrative paints a picture of when motorways were glamorous and service stations acted as venues for everything from Sunday lunch to christenings, complete with postcards to send home! This is the final part of three.
