As has been mentioned there is now a slip road/underpass taking traffic from the A13 to the A130, taking you straight onto a smallish roundabout connecting to the A127. This is the cause of the traffic hold ups that I warned Jock about as traffic going south on the A130 has to turn right at this roundabout. Now in the evening rush most traffic towards Southend uses the A13 and then diverts here to the A127 so that at the roundabout traffic from the A130 has to wait for a gap in the traffic from the A13, which during the evening rush is not very often. Essex County Council is very fond of putting traffic lights on roundabouts so why not on this one?
The worst hold ups on the A13 occur when something goes wrong at the Dartford crossing. On the approach to the M25 there is 3 lanes, the inside one being marked out for traffic going across the river. If there is a problem the queue in this lane can be as long as a mile or more. The cockwombles don't want to queue up instead drive to the front of the queue and try to force their way in and in doing so obstruct the other two lanes.
A bit overcast here in Estuary-Land at the moment but according to the weather forecast it should brighten up later, keeping fingers etc. crossed. Hope everything goes well for your grandson Jock, I'll be thinking of him as will other ER's.
