Unfinished part of the M23?

If you look on Google earth at the northern most bit of the M23 north
of the M25 just where it joins the A23 you can see what looks like an
unmetalled bit of the motorway continue over a bridge with trucks and
cars parked on it. Further on still theres a completely unused bridge
that goes over the A23 surrounded by scrubby woods.
Anyone know what this bit is used for now and was the M23 originally
supposed to have continued further north than it does now?

Turn on the "Google Earth Community" layer in Google Earth. Someone
called "londingham" has placed a placemark there with a comment that it
was left unfinished in the 1970's.

No idea about what the bit is used for though, but looks like some kind
of storage area for highway construction/maintenance works or something
like that.

I don't know of a better site for this sort of thing than CBRD:
http://www.cbrd.co.uk/histories/m23/

Unless it's www.pathetic.org.uk of course, but AFAICS he doesn't cover
the "lost" M23 extension.

Yes, it was to have continued as far as Balham, from where spurs would
have connected it to the inner London Ringway ("London Motorway Box").
The only bits of the latter to be built were the sections either side of
the Blackwall Tunnel, plus the tiny bit of (former) motorway from
Westway down to the Shepherd's Bush roundabout:

Everything else was abandoned due to the cost and unacceptability of
demolishing tens of thousands of properties.

In which case it really WOULD have become the 'Gateway to the South'

I'm pretty sure they dug it up. There are, after all, hurriedly
constructed runways on wartime airfields which are still there 60 years
later.

Good point. I know there are plenty of sections small roads that have
been just cut off and left to their own devices but are there any
large sections of A roads (or motorways) that were bypassed and
disused and just left alone?

I don't know, but IMO the Great Dunmow Bypass should be decommissioned or
turned back into a railway when it next needs resurfacing. The new A120 has
rendered it pretty redundant.

Probably the longest stretch I know of: when the M74 opened, the A74
trunk dual carriageway was converted to single carriageway B-road, with
the whole length of the second carriageway being abandoned to nature.
