Introduction

The A303 is the middle section of the London-Exeter trunk road. The A303 takes a more northerly route though Salisbury plain than the A30 and it is mostly D2. Passing places like Andover, Stonehenge and Wincanton, it also carries much of the Summer traffic from London.

Route

The Amesbury bypass in 2007
Main Article: A303/Route

The A303 has a variety of standards along its route. From a high quality grade-separated dual-carriageway in the east, it ends up as a winding single-carriageway road in the west, with various standards in between. The route description examines them.

History

Main Article: A303/History

The current A303 began life in 1933, cobbling together various different roads to make a coherent through route. Made up of lots of various roads, some dating to 2000 BC in the Stonehenge area, it has had a vast array of improvements. When the M3 opened, the A303 and not the A30 became the main trunk road between Basingstoke and Devonshire House.

Notable locations and improvements
