A303 Amesbury to Berwick Down – Stonehenge

This project is to build a 1.8 mile (2.9 kilometre) tunnel under the World Heritage Site (WHS), a bypass for Winterbourne Stoke and improve the existing junctions between the A303 and the intersecting A345 and A360.
This challenging commission required the consolidation and write up of bespoke project case studies from completed schemes around the world. This was achieved through effective communication and collaboration with the various joint venture partners, resulting in not only a high quality, detailed submission but a significant library of detailed case studies for future use – maximising the value of our time on the project.
WeBid additionally managed the competitive dialogue sessions with the JV team to present to National Highways.
