More than 310 miles of roads across Surrey will be replaced as part of a £100m investment from the county council to tackle the root causes of potholes.

The worst roads in Surrey will be targeted, with Operation Horizon replacing 10 per cent of the county’s highways in the next five years.

More than 75 per cent of the roads were nominated by residents at a series of public events held last year.

The work will be spread across the county and each borough and district will have between 10 and 13 per cent of their worst roads replaced.

John Furey, Surrey County Council’s cabinet member for transport and environment, said: “Operation Horizon will lead to big improvements with the worst roads being resurfaced or replaced completely.

“Highways will stay in a good condition for longer, meaning far fewer repairs are needed, less road closures will take place and traffic congestion is reduced.”

The £100m comprises an extra £25m from next year’s council tax rise, reducing costs by £15m, a new five year approach to planning road improvements and using new materials that will keep roads smoother for longer.

The final list of roads will be published in April.
