This annual release presents information on the condition of roads in England, covering surface condition, skidding resistance and highway maintenance treatments and expenditure

Automated survey machines and visual surveys are used by Local Authorities and National Highways (NH) to monitor the condition of the road surface.

Figures in this report only include Local Authorities with valid data available. Data is available for fewer London Local Authorities for the last 3 years in this release, due to changes to how surveys in London were carried out. We estimate that this has had limited impact on the headline figures.
