Graham has been awarded a package of road improvement works by Highways England covering four major A-roads in the east of England.
The £19m contract will see Graham take on safety improvements, surfacing and technology schemes on the A1, A11, A12 and A47.
The projects extend from Peterborough to Norwich and through to Lowestoft via Great Yarmouth and form part of a Collaborative Delivery Framework (CDF), which groups projects dependent on the area of completion.
Graham highways director Dave Brown said: “We are delighted to be working with Highways England on this prestigious contract, it is really encouraging to see that our long-standing and collaborative relationship continues to grow stronger.
“We look forward to working in partnership with the CDF community to ensure the project is completed safely and to the highest possible standards.”
Highways England is in the process of finalising how it will procure the next stage of improvement works on the UK’s roads following the end of the CDF, expected next year.
New procurement routes will replace the current CDF, which was launched in 2014 to cover enhancement works and is due to be scrapped when it reaches its £5bn OJEU limit.
Earlier this month Highways England announced a series of works packages that will help drive housing developments across the East Midlands and South-east.
The organisation said the schemes, worth £45.5m, will facilitate the development of up to 10,000 new homes.
They include improvements to junction 23 of the M1, junction 9 of the M27 and Anstey Lane on the A46 / A560.
