Graham has won the contract to deliver the £90m Congleton Link road in Cheshire.
Cheshire East Council selected the contractor for the 5.5 km road just outside of Congleton, with Graham beating several bidders to the deal.
The scheme, which will include two road bridge crossings and two underpasses, will link the A536 Macclesfield Road with the A534 Sandbach Road to the north of Congleton.
It will also support the construction of 2,400 homes and improve connectivity for HS2 construction traffic when phase two of the £55.7bn line begins.
The council will contribute £24m to the scheme, while also seeking a further £45m from the government. The remaining costs will be met by developer contributions.
Work is expected to begin in November on the basis that the council receives funding sign-off from the Department for Transport.
The road is expected to open to traffic in autumn 2020.
Graham is among the firms on the medium lot of Highways England’s Collaborative Delivery Framework, covering schemes up to £25m.
Last year it landed a £19m deal through the CDF for improvements to four major A roads in the East of England.
Graham saw its margin dip to 1.7 per cent for the year to 31 March 2018, down from 2.8 per cent in 2017, in accounts published last month.
Pre-tax profit fell to £13.1m for the year, compared with £16m during the previous 12 months.
In its accounts, the contractor identified the North-west and the West Midlands as growth areas for the coming 12 months.
