travelling north they still have the barriers at the moment, you have to come to an almost stop before they rise, so there are still queues, but not as bad as they usually are, southbound, they route everyone round the barriers, so its 4 lanes with a wiggle in, maybe 40mph max, but moving, tonight there was a broken down lorry, right opposite where the barriers were, and we still sailed through at 40mph. its a shame I then got stuck for an hour at Brenley corner just outside faversham due to barrier repairs. hit the back of that queue at just after 6pm, got home 5 miles further 7.20pm.
