ONE lane of a major road was closed which is causing heavy morning traffic.

One lane of the A12 London-bound was closed earlier this morning.

It has since reopened, however traffic is still queueing for four to six miles and up to 40 minutes.

It was due to a collision involving two vehicles at Junction 20 Hatfield Peverel.

Queues are currently back to J24 Kelvedon north.

Drivers should expect delays.
