A trip to South Wales with a friend at the weekend saw part of the journey undertaken on the M50 motorway, or Ross Spur as it is sometimes known, and as a passenger I was able to appreciate the unique character of this odd little road. While many readers would probably consider roads in general to be boring and motorways especially so, the M50 is actually rather interesting, despite being a mere 21 miles long with only four junctions. Being one of Britain's oldest motorways but lightly used and little modified since it was built, it is probably as close as it is possible to get to an authentic 1960s motorway travel experience, and one of those four junctions is also rather remarkable.
