Road lengths by road type

Road length statistics (in miles, and kilometres) for all publicly maintained roads in Surrey. This covers all centrally and locally managed roads.

As of 2023, the county contained a total of 3,409 miles of road network (5,486 km).

This comprised:

63.6 miles of motorways (102.4 km)

387.0 miles of A-roads (622.8 km)

245.4 miles of B-roads (394.9 km)

2,713.0 miles of C- and U-roads (4,366.1)

A-roads are the highest class of classified road in the UK, and are considered the main roads in the country. They are major roads that connect regional towns and cities, and are often the main arteries to major destinations. A-roads are usually among the widest and most direct roads in an area, and are of the greatest significance to through traffic.

B-roads feed traffic between A-roads and smaller roads, and connect different areas. B-roads are still of significance to traffic, but less so than A-roads.

C-roads are unnumbered smaller roads that connect unclassified roads with A and B roads.

• Unclassified roads ('U-roads') are local roads intended for local traffic, and are of the least important categories.

Data on road length by region, country, road type and local authority, is produced by the Department for Transport. All data is published here: Road length statistics (RDL) - GOV.UK
