As a matter of interest, why is the Queen Elizabeth II Bridge not
designated as a Motorway?

So that traffic which is prohibited from using motorways can still cross
the river.

Not so.

Pedestrians and cyclists cannot use the crossing in either direction
(except as passengers and freight).

The Dartford Tunnel was built by Kent and Essex County Councils and was
opened to traffic over ten years before any part of M25 was opened and
about twenty years before the tunnel approach roads were fully connected
to the M25 northbound.

A282 was allocated when the tunnel (at that time a single bore) was a
standalone facility.
