A249 Grovehurst Road and interchange junction

We have been awarded £38.1million from the Housing and Infrastructure Fund to deliver highway improvements at two junctions of the A249 to the west of Sittingbourne:

The scheme to improve the Grovehurst Road and A249 junction will replace the existing “dumbbell” junction with a two-bridge flyover.

The improvements constructed by Jackson Civil Engineering to the A249/Grovehurst Road include:

  • replacing the existing junction with a two-bridge flyover
  • removing the current roundabouts and constructing an additional bridge to create a loop over the A249.

Scheme cost

The £38.6 million is funded by £38.1 million from the Housing Infrastructure Fund Grant.

Scheme documents

Due to the congestion on the roads, we as the local authority highway and Highways England are dedicated to improving the safety in this area of development.

The improvement scheme will increase capacity on the road network, and provide the infrastructure needed for the housing plans in Swale’s adopted local plan to be delivered. The housing plans consist of 4,628 new homes planned on the A249 corridor from the junction with the M2 to the Isle of Sheppey.

Formal decision

The approval to progress the scheme was taken by Kent County Council on 27 April 2020.

Planning consent for the Grovehurst Road scheme was granted on 16 March 2022.

In Kent, we are responsible for all public roads except motorways and trunk roads. The M2 and A249 are managed by National Highways.


The diversion routes are clearly marked, including big signs letting drivers know Sheppey Way is not suitable for HGVs.

Despite the official diversion route not passing through Iwade, we understand motorists often look for the most convenient and direct route. We will continuously monitor and review the impact on Iwade.

Currently, the traffic management plan is in place until summer 2024. Any changes to the programme will be communicated to residents and businesses. To be notified of any changes email GrovehurstRoad@jackson-civils.co.uk to join our mailing list.
