South East - Maintenance schemes

Maintenance schemes taking place in the South East region.

The latest maintenance schemes that will be running in this area can be found below in the 'Project information area'.

Project information

You can find more details about Ash die back works below:

Over the summer, we need to remove or make safe ash trees identified as needing urgent action.

You can view more details about the maintenance schemes taking place on the A2 below:

Work

We're improving the flyover that connects the A2 westbound with the A282 northbound towards the Dartford Crossing. This work will improve safety and make journey times more reliable.

Closures

We need to close the flyover completely over the weekend to resurface it safely in one continuous operation.

Start: 8pm Saturday 6 September
End: 5:30am Monday 8 September

The flyover will be closed throughout Sunday 7 September.

Diversion:

A signed diversion route, which is suitable for all traffic, will be in place via M25 junction 2:

Exit the A2 westbound at M25 junction 2
continue around the M25 junction 2 Darenth Interchange
take the fourth exit to join to the A282 northbound

The traffic signals around the interchange will be reconfigured to help manage traffic through M25 junction 2 while the flyover is closed.

We’ve planned to do this work at a weekend while there is less traffic. However, we’re expecting delays around M25 junction 2 at peak times during the Sunday.

If you need to travel while this work is taking place, we recommend you plan ahead and leave extra time for journeys.

We’ll reopen the flyover as soon as the new materials have sufficiently cooled and strengthened enough for the road to be driven on.

Closures can change at short notice and this work will be weather dependent.
