The scheme on this section of A303 is between Amesbury and Berwick Down, where the road runs through Stonehenge, Avebury and associated World Heritage sites, passing 165 metres from Stonehenge itself.
It is a single carriageway section about 12 km long, starting east of Countess roundabout at Amesbury and ending just west of Winterbourne Stoke, and cuts the World Heritage site in two.
Over the past 25 years, more than 60 potential routes have been examined and Highways England (HE) have undertaken a fresh review to search for the best route. Route corridors were identified and then assessed.
The assessments and conclusions
The proposed scheme is for a tunnel route through the World Heritage site, together with a by-pass of Winterbourne Stoke, passing either to the north or south of the village.
- Route option D061 – 2.9km length tunnel with route running north of Winterbourne Stoke, the eastern tunnel portal located east of The Avenue and the western tunnel portal located west of Normanton Gorse
- Route option D062 – 2.9km length tunnel with route running south of Winterbourne Stoke, the eastern tunnel portal located east of The Avenue and the western tunnel portal located west of Normanton Gorse
Highways England launched a public consultation on 12 January 2017, which ran until 5 March 2017, for public and key stakeholders to comment on their proposals and identify any areas of concern or opportunities for further improvement.
