Subject to planning permission, Junction 10a will be built approximately 700 metres east of the existing junction 10 near Ashford in Kent.
The new junction will use two bridges and connect to the existing A20 and a new dual carriageway link road built to the A2070 near Sevington.
Highways England regional director for major projects Chris Welby-Everard said that the contract had been let early “so that if planning permission is granted we can start work as soon as possible”.
Peter Whitman, highways sector director for Vinci Construction JV, said: “This is an important contract for us as it will be the first Highways England contract delivered solely by Vinci Construction and demonstrates our continued growth in the strategic roads sector.”
The scheme is currently progressing through the development consent order examination process at the Planning Inspectorate, with the preliminary hearing having taken place on 2nd December 2016. Construction of the scheme is conditional of planning permission being granted.
Vinci was chosen as the preferred supplier using the collaborative delivery framework Lot 3a as a design and build contract. It will work alongside consulting engineer Jacobs, from Lot 1 of the same framework.
