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.
Closures are planned across the A2, A21, A20, and A282 routes, with most works taking place overnight to minimise disruption. Here is a day-by-day breakdown of scheduled closures from Monday, March 31 to Sunday, April 6.
