Watch A303: Highway to the Sun (2011) Official Trailer

Writer Tom Fort drives the 92-mile length of the A303 in a lovingly-restored Morris Traveller. Along the way he has many adventures - he digs up the 1960s master plan for the A303's dreams of superhighway status; meets up with a Neolithic traveller who knew the road like the back of his hand; gets to know a section of the Roman 303; uncovers a medieval murder mystery; and discovers what lies at the end of the Highway to the Sun.
