Surrey County Council has said it is set to confirm savings of nearly £170,000 made every day for a year.
The county council said annual figures are due to show that it saved £62 million for taxpayers in the last financial year.
That figure, it said, will “propel” the savings total since 2010 to almost £260 million.
The sum would be enough to pay for the council’s Operation Horizon project - to completely overhaul more than 300 miles of county roads most in need of repair - two-and-a-half times over.
The council plans to find another £250 million of savings in the next five years as it continues to face the challenge of falling funding and rising demand for services.
At the start of the year, council leader David Hodge, pledging to work week in, week out, to make savings, unveiled a document highlighting more than 50 ways the council had worked to improve the efficiency and effectiveness of services.
Mr Hodge said: “By doing things more efficiently and working with other organisations as one team, we’re ensuring taxpayers’ money stretches further, while continuing to provide excellent services to Surrey’s residents.”
He said: “Saving £62 million in one year – at a rate of almost £170,000 a day – bears testament to that, and we’ll continue finding innovative ways to do more for less at a time when demand for our services is rising and funding is falling.”
The authority has joined forces with emergency services, health organisations and other councils in Surrey and Sussex to transform public services through closer working.
It is also part of the South East 7 group of councils working to improve services and cut costs, and is a member of the Surrey Future partnership, formed to stimulate economic growth.
