The first, main phase of works starts soon on the A259 major improvement scheme.
The scheme will widen a total of about 2km of single carriageway to dual carriageway in Angmering and Littlehampton and includes:
- Widening part of Worthing Road in Littlehampton to a dual carriageway from the new Lyminster Bypass roundabout at Highdown Drive (under construction) to the Body Shop Roundabout. A new pedestrian and cycling path will be installed to the south. The existing controlled crossing point will be retained.
- Widening the Roundstone Bypass in Angmering to a dual carriageway between the Station Road Roundabout in Angmering and the A280 Roundabout. This will feature a new cycling and pedestrian route to the south, separated from the main carriageway by a verge. New controlled pedestrian crossing points will be included at Haskins and at Station Road.
Once complete, the improvements will reduce traffic congestion by increasing road capacity and so cut both journey times and pollution.
Preparation work is ongoing and the first main phase will begin with weekend, night-time closures and diversions in place:
Littlehampton end of the scheme:
- Sunday, 4 October, night-time closure: traffic management will be installed for the safety of both road users and the workforce around the central islands, which are to be removed or adjusted. A 30mph, temporary speed limit will be introduced between Highdown Drive and the Body Shop Roundabout. Right-hand turns into Olliver Acre and Cornfield Close will be temporarily prohibited.
- October 5 to 10, two-way traffic will run on reduced road widths while the traffic island work is ongoing. On Saturday, October 10, the A259 will be closed overnight at the Littlehampton side of the scheme to install traffic management and a contraflow system, which remain for about 11 months.
In Angmering, between the Station Road and A280 junctions:
- A night-time closure on Sunday 11 October while traffic management is installed around the central islands and 40mph zones will be introduced. Right-hand turns into Lowertrees Nursery will then be permanently prohibited.
- From October 12 to 16, two-way traffic will be running on reduced road widths while traffic islands are removed or adjusted.
- A night-time closure will follow on Saturday and Sunday, 17 and 18 October, to install traffic management, with narrow lanes and a 40mph zone will be introduced between the junctions.
A West Sussex Highways spokesperson said: “Every effort will be made to limit inconvenience during this major improvement scheme but there will be some disruption, for which we apologise.
“Road users are advised to please take an alternative route, if possible, or allow extra time for their journeys.”
Letters have been distributed to nearby residents and the scheme’s web page www.westsussex.gov.uk/A259 will be updated during the different construction phases.
