24,000 miles of local roads in England and Wales need to be repaired in the next 12 months but underfunding has caused a backlog, warns a report.
An ageing network, decades of underfunding, increased traffic as well as harsh weather conditions are all factors, says a report by the Annual Local Authority Road Maintenance.
It warns it could impact the economy with underfunding causing a backlog of road maintenance.
Local authority highway departments report it would take 14 years, with adequate resources and funding, to get roads back into a steady state.
Despite the Department for Transport's funding for local road maintenance at the highest it's been over a decade, around £1.2 billion a year, and a further £1bn form council reserves and borrowing - the total spend still falls short of the amount needed to halt the decline.
