Especially as I've taken pains to explain the tunnel was built in the

Why was it built in Dartford though, when a tunnel from Gravesend to
Tilbury would fit in much better with the pre-M25 road network... or was
it because the M25 was already planned when the first tunnel was dug.

The M25 evolved gradually from the pre-war North Orbital and South Orbital
"parkway" motorways, which according to CBRD were going to be joined by
a new tunnel between Thurrock and Dartford.

It should be noted that this page suggests (if only by order of mention)
the primary Northern Orbital terminus would be Tilbury Ferry and docks,
by the way.
