I don't know how long it took to release vehicles trapped behind the
accident. No doubt many passengers missed planes at Stansted.

Are those "stuck" not eventually directed to go back the "wrong way" and
off at the first junction? Obviously you'd need some traffic plod at
the top of the slip road, which, being an *entrance* to the motorway is
not designed for people coming up it and onto the roundabout that is
typically at the top.
