Though by definition, they’re quite hard to trace, unless you have access to an old map.
I can't think of an awful lot that I knew about. M6/A6 south of Penrith (probably too short-lived to be on any map); M90/A90 north of Denny; M9/A876 SE of J7; can't think of many others offhand.
Edit: and at the ends of the Cullompton bypass, later M5.

I can't work out why one would have been necessary at Copdock, given that as far as I can recall the two roads were simultaneous, and the Ipswich bypass does seem to be higher level than the old A12 there.

M40 at Beaconsfield was a temporary roundabout prior to J2 I think, near to where the garden centre on the A40 is now.

I see it. Immediately east of the side road Walkwood Rise. I either never knew about that or had forgotten.

Sorry for the late replies but I've been on holiday for a few weeks.

I've driven northbound on this section several hundred times and never noticed that the RCS just north of the Parkgate flyover is unnecessary, being just a mile further on than the one at j5.

@nirs also put up a map of the route, albeit not an original OS map

Thanks for those, very interesting.

See attached photo of the relevant page. It seems that traffic joining the M2 was able to do so free-flow, but traffic exiting the M2 eastbound had to give-way to traffic on Paradise Walk.

A RCS would have been redundant once the temporary terminus disappeared, as you only need an RCS sign when joining a motorway.

Fantastic nirs I've waited many years to see this arrangement. For some reason I didn't expect it to be full access, i.e. I didn't know travelling southbound you could turn left off the motorway and end up in the middle of Parkgate village. I would love to see a picture of the signage at this temporary junction, I wonder if one exists anywhere.

It was indeed 'Falls Road'.

I always thought the choice of destinations was a bit odd. People who didn't know Belfast might have had no idea where 'Falls Road' and 'Shaftesbury Square' were in the city. And that was the only options you got on the ADS.

Bit of thread necromancy, I know, but SABRE Maps now has the M8 Harthill Bypass on the 1966 One Inch map layer, including the temporary terminii at both ends.

The former alignment of the A74(M)-A74 link north of the present J16, which was the north end of a section of the A74(M) from December 1994 to May 1999, can be made out in Google's satellite view.

The M11 terminated on a roundabout at Stump Cross at J9a as I recall - just about here.

How about the western end of the M56 for a dubious entry! A roundabout terminus converted to freeflow but not really an extension of the motorway (unless you believe Google Maps).

The M20 had a temporary terminus at West Kingsdown, where the section from J1 (Swanley) ended for a few years on the A20 at a T junction!

Another well know waypoint that has disappeared from common use is Norman Cross which was alongside the A1 until it was upgraded to A1(M) when the monument was moved to a new site in Yaxley.
https://www.sabre-roads.org.uk/wiki/ind ... rman_Cross

From the SABRE Wiki: Norman Cross :

Norman Cross is junction 16 of the A1(M) and the southern end of the A15. The name derives from Norsemen's Cross and was the site of a Napoleonic Prisoner of War depot that existed from 1797 to 1814 (source: Friends of Norman Cross). There is a memorial to the site next to the junction.
