These planned works aim to improve road safety and infrastructure, with closures affecting key slip roads, carriageways, and tunnels.
Drivers are advised to prepare for possible disruptions as essential maintenance takes place, including resurfacing, structural improvements, and electrical works.
National Highways oversees motorways and major A-roads, meaning smaller road closures are not included in this schedule.
The A2 serves as a vital connection between Dover and the heart of London, spanning nearly 72 miles from Borough to Dover Docks.
