The contract award by the Highways Agency follows on from Costain’s delivery of the early contractor involvement (ECI) phase of the scheme. Costain developed the detailed design and took the project through the new national planning process.
Major improvements will be carried out between M6 Junction 19 at Knutsford and M56 Junction 7 near Bowdon to create a dual carriageway over its 4 miles (6.5km) length. The scheme has been designated by the Highways Agency as a Nationally Significant Infrastructure Project.
Work will begin immediately, with the new link road expected to open in 2016/7.
Costain chief executive Andrew Wyllie said: “We are delighted to have secured the delivery phase of this vital scheme, following our successful work during the ECI phase in providing specialist design consultation and securing planning approval.”
