Hardwick Roundabout in Kings Lynn finally got its flyover in 2003, but it wasn't what the locals had expected. Is it the UK's most misunderstood junction?

In this first Imperfectly Odd outing, we take a trip to northern Lancashire to see one of the most peculiar motorways in the UK, and one with the strangest history.
