A study to determine future improvement schemes along the Arun section of the A259 is being undertaken by West Sussex County Council.
The authority commissioned the study in anticipation of heavier volumes of traffic using the A259 in future years.
In addition to planning permission being granted for new retail developments such as the ASDA superstore in Ferring, new housing is needed to house the growing local population according to the emerging Local Plan for Arun.
The study area focuses on the A259 within the Arun district, from the River Arun (west of Littlehampton) up to and including the Goring Crossroads roundabout.
Sections of the A259 to be assessed include:
A280 Angmering Bypass roundabout (A259/A280);
Goring Crossways roundabout (A259/A2032); and
The remaining sections of the single carriageway road.
County Council Cabinet Member for Children and Families, Peter Evans, who is member for East Preston and Ferring, said: “We as an authority recognise that we need to help the traffic flow in the area.
“This study will accurately predict what can be done in the most cost effective way.”
