The joint venture had been standing by as approved contractor, waiting for ministers to agree full funding for the ВЈ62m scheme. This has now been signed off and work on the three year project can begin.
Jacobs, as part of Kent Highway Services, will be supervising the works on behalf of Kent County Council.
The work includes the design and construction of about 8km of dual two lane carriageway including a number of roundabouts and two railway crossings.
The main activity during the coming months will be to carry out an archaeological investigation. This will free up areas of the site so key construction activities can start.
The contractors will also aim to develop the design and build elements of the project, such as the large underpass beneath Foads Hill and the railway at Cliffsend.
It is expected that the new road will be fully opened to traffic in 2012.
