These are part of a planned maintenance to boost road safety and infrastructure.
Drivers are forewarned that diversions and delays might accompany these crucial works.
National Highways maintains motorways and major A-roads, so smaller road shutdowns are not on its schedule.
The A2 serves as a crucial link connecting Dover to the heart of London. It spans nearly 72 miles from Borough in the capital and finishes at the Dover Docks.
