THERE is heavy traffic out of the city leading onto the A23 due to a vehicle break down.

Queues are stretching northbound along London Road in Brighton from the roundabout that meets the A23 all the way back to Preston Park.

There are delays of at least six minutes between Mill Road and The Deneway. 

The average speed along the section of road is around 5mph.

As of 7pm, there is still heavy traffic going back all the way to Carden Avenue due to the break down.
