Three months of speed enforcements on the A21 are set to cause traffic chaos.

Narrow lanes and a 50mph speed limit will be in place along the Sevenoaks Bypass in both directions between Morleys Roundabout and the A21/A25 junction.

Work is being carried out to replace the central reservation barrier and will run from Friday, January 9 until Monday, March 30.

The Highways Agency has issued advice to motorists who will be travelling along the road:

• Keep within the speed limit – it is there for your safety.
• Get into the correct lane in good time – don’t keep switching.
• Concentrate on the road ahead, not the roadworks.
• Be alert for works’ traffic leaving or entering roadworks.
• Keep a safe distance – there could be queues in front.
• Observe all signs – they are there to help you.
