OVERNIGHT road closures will affect motorists using the A27 between the Ford roundabout and Crossbush.
The closures are needed to allow improvements to take place. On Saturday, January 21 overnight work will resurface just over half a mile of the road between the Causeway Roundabout and Crossbush interchange.
It is due to be completed by February after being carried out from 8pm-6am each night.
The first week will see both carriageways of the road shut. Drivers will be sent on a diversion through Bognor Regis.
From January 28 until February 14, there will be lane closures, temporary traffic lights and a 40mph speed limit with users escorted past the works at 10mph.
