The works in Chelmsford, Essex include a new viaduct over the Great Eastern railway and A12 and carriageway works (RDR Phase 3) linking into the Boreham Interchange.
The scheme, which is being directed by Countryside Zest in partnership with Highways England, is subject to a single-phase procurement process although the works will be split into two phases.
The first, a £1.4million valued Stage 1 Pre-Construction Services appointment, will focus on design development in order to secure technical approval from the relevant authorities, including Highways England and Network Rail.

Stage 2 Construction, with an estimated value of £11.8m, will then involve the commencement of an engineering and construction programme based on the agreed outputs from Stage 1.
Graham previously completed the award winning A138 Chelmer Viaduct – a £32m strategic highway, which has increased transport capacity and significantly improved journeys for motorists, cyclists and pedestrians.
Graham Managing Director for Civil Engineering, Leo Martin, said: "This contract award is a tremendous result for us and it once again underlines our combined approach and reputation for excellence in both the highways and rail sectors.
"The first phase of this contract requires a fully-coordinated design methodology that meets the approval and standards of Highways England and Network Rail. We have enjoyed long-term relationships with both organisations and fully understand their technical requirements.
"I'm confident that our existing knowledge and design expertise will not only meet, but exceed, their expectations, which will ensure a seamless transition to Stage 2 and the beginning of the construction works."
