A serious crash has sparked a large emergency response and gridlock on a busy dual-carriageway.

Police and paramedics are at the scene of the accident on the A299 New Thanet Way at Herne Bay.

An air ambulance also landed in the town’s Memorial Park but has since taken off with no casualties onboard.

The crash – understood to have involved multiple vehicles – has sparked long queues between the Herne Bay on-slip and Bullockstone Road flyover.

Some motorists were seen trying to avoid the queues by driving the wrong way up the slip-road, but police have since cordoned off the makeshift exit.

Meanwhile, traffic is building up in the area as vehicles come off at Herne Bay to steer clear of the jams.

A police spokesperson said: “Kent Police was called at 1.09pm on Friday 23 February 2024 to reports of a collision involving two cars on the London-bound carriageway of A299 near to Herne Bay.

“Officers are currently at the scene with Southeast Coast Ambulance Service and the driver of one of the cars has sustained serious injuries not deemed to be life threatening.

“One lane of the carriageway remains closed whilst recovery of the vehicles is arranged.”
