ROAD works are taking place on the eastbound and westbound carriageways of the A27 Polegate Bypass later next month.
Markings on the road are also being renewed on the Cophall Farm Roundabout.
All the work is taking place for one week from from August 30 - between 8pm and 6am each week night.
There will be carriageway closures on the bypass during these hours with a fully signed diversion in place.
Eastbound road users will be diverted at the Cophall Farm roundabout onto the A2270, the A2021, Cross Levels Way, and the A22 to rejoin the A27.
Westbound road users will follow the above diversion route but in the opposite direction.
When work is taking place on the Cophall Farm Roundabout there will be a 50mph speed limit in operation and lane closures around the roundabout.
