These planned upgrades are designed to enhance road safety and improve infrastructure, ensuring smoother journeys in the long run.
National Highways is responsible for major roads and motorways, so smaller road closures will not be included in this schedule.
The A2 is a key route linking Dover with central London, stretching approximately 72 miles from Borough in the capital to the Dover Docks.
The A21 serves as a primary connection between London and Hastings, while the A20 is an essential link to Dover.
The A282 forms part of the crucial Dartford Crossing, a major route across the River Thames.
