These planned roadworks aim to improve road safety and infrastructure, with overnight closures in place across key routes.
Motorists are advised to check for updates and plan alternative routes where necessary.
National Highways oversees these major A-road and motorway closures, so smaller road disruptions are not included in this schedule.
The A2, A20, A282, and A21 serve as crucial transport links, connecting London, Kent, and the South East, including key access points such as Dover Docks and the Dartford Crossing.
