M25 Dartford Crossing closure: Your story

6 September 2013 Last updated at 23:02 BST

Drivers have been stuck in huge queues after the M25 Dartford Crossing between Kent and Essex was closed in both directions because of a security alert.

Police ordered the closure when a pedestrian was arrested after being spotted behaving unusually, at about 16:00 BST. The Queen Elizabeth II Bridge was shut at 17:00 BST, with both tunnels shut 20 minutes later.

Commuter Mike Partridge, who was heading southbound on the M25, told the BBC how he persuaded an ice cream seller to open up for business.
