In this episode of the Scottish Roadscast, John and Stuart consider the history behind the A78 between Greenock and Prestwick. Over 40 miles long, it's one of Scotland's most varied routes. One minute you're driving by stunning coastline, the next you're on a three lane fast moving expressway. Our "From the Archive" feature takes a look at the A78 Three Towns Bypass booklet from 2004!
