The right-hand tunnel has been shut and emergency services are on the scene.

A height restriction of 15ft 9in has been put in place and things are expected to be clear at around 1.30pm.

Ambulance service spokesman Rich Airey said: "One ambulance crew attended the scene and one patient has been taken to Darent Valley Hospital."

Police have been contacted for more information.
