Lafarge Tarmac is on the verge of being awarded a highway maintenance deal for roads across Norfolk.
Norfolk County Council says the deal, which is worth between £300 million and £480m over 12 years, could save taxpayers up to £4.4m a year.
It is expected to be rubber stamped at a cabinet meeting on Monday (5 August).
The current contract is being run by May Gurney and expires in March 2014.
Pothole repairs and patching, surfacing and surface dressing, white lining and highway construction projects all fall under the contract remit.
