The planned maintenance, overseen by National Highways, aims to improve road safety and infrastructure.
Drivers in Kent and surrounding areas should prepare for possible delays and diversions during these works.
The A2 is a key transport route linking Dover with central London, spanning nearly 72 miles from Borough to the Dover Docks.
National Highways is responsible for maintaining these major roads, while smaller local routes fall outside its remit.
