Preparation work has begun to build a flyover across the Stockbury roundabout at Sittingbourne.
Diggers and earth-moving machines are under the M2 bridge next to the A249 to clear away bushes, shrubs and trees.

The work will include diverting underground water pipes, electricity cables and phone lines.
Contractors are building a works compound and skimming off the top soil where new roads will go. Archaeologists are also on site searching for hidden clues to the past.
National Highways said most of the work will be away from the busy A249 Sheppey to Maidstone road and will not need any any lane closures, although part of the Sittingbourne-bound carriageway from Detling is coned off to allow diggers access to nearby fields.
There are also temporary traffic lights on the Maidstone Road near its junction with the roundabout.
Contractors have warned there will be times when the A249 will need to be shut at night and at weekends to divert utilities.
Main construction work is expected to begin in January and will continue until winter 2024.
The £92million upgrade was given the green light in June by the Secretary of State for Transport Grant Shapps following a public inquiry.
It will feature a new flyover over the top of the existing roundabout to provide non-stop movement between Maidstone, Sittingbourne and Sheppey.
Two new slip roads are being created to let traffic join the M2.
The work is being carried out by Graham.
