What is the A303?
The A303 is a major trunk road that winds its way from Basingstoke in Hampshire to Honiton in Devon – taking in Stonehenge along the way.
It is also the connecting road between the M3 and A30, making it one of the primary routes from London and the South East to Devon and Cornwall. The road passes through five counties along the way.
Why is the A303 so notorious for heavy traffic and jams?
The A303 is 93 miles long as it takes drivers from the M3 near Basingstoke at Juntion 8 to the A30 in Devon. However, the route is made up of both dual and single carriageway roads, causing numerous pinch-points and big jams at peak times.
It’s also an attractive route, that takes in the likes of Stonehenge – where long delays occur as drivers slow down on the single carriageway road to admire the clearly visible monument.
All this – and sheer weight of traffic – conspire to create a route that can add many hours on to your trip towards destinations in the likes of Devon and Cornwall.
