I can say there are no roadworks. It is a traffic management design for the air show. It stops traffic from turning right when coming from the west travelling East. They also turn off the lights so no one stops. The queuing traffic is much further back before the junction into the airport.
If it had been a normal day the fatalities would have been so very much worse.
I hope at some point that all those sadly affected can find some peace.
