December 2018 performance
The results of the 2018 condition survey of the Principal A-Road network gives confidence that our aim to keep those A-Roads considered poor and requiring maintenance to below 5% is being achieved and remains “On Track”.  The continued monitoring of the A-Road condition will inform future maintenance funding investment decisions
April 2018 performance
12.5% of the roads in West Sussex are catergorised as Principal (A-Class) roads. In general these are the major distributor roads, between the main towns and urban centres (not including Motorways or Trunk Roads.)
Each year we survey 100% of the A-roads using Scanner Survey vehicles.


The local highway network is the most valuable publicly owned asset managed by West Sussex County Council. The strategic approach seeks to optimise the value of West Sussex’s highway infrastructure over its whole life. The Principal A-Road network includes the major roads within the County that provide large scale transport links, and support the regional and local economy. They equate for 12.5% of the roads in West Sussex. Through effective long term planning and forecasting of the principal roads performance we strive to minimise and prevent expensive short-term repairs, promoting the timely investment in maintenance based on need. This approach aims to retain a steady state in the poor (red) condition of principal roads, whilst increasing the overall percentage of roads in a good (green) condition.

Red Condition: Poor overall condition likely to require planned maintenance soon
Amber Condition: Some deterioration apparent – investigate to determine the optimum time for planned maintenance treatment
Green Condition: Carriageway is generally in a good state of repair
