I think temporary roundabouts were quite common between the 60s and the 80s/90s.
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.

The significance of the replacement is that nobody appears to have assessed whether it was still needed in the first place!
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 has a writeup of a visit, if you look on google maps you can see where the road would've met the motorway

I have a set of the original contract blueprints for the M2 from Paradise Walk to Antrim, which shows the temporary layout as *proposed* though I suppose I can't be 100% sure that it was built exactly like that. 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.

I can't quite tell - it's probably either "Donegall Road" or "Falls Road", i.e. a fairly local direction sign. Falls probably makes more sense in the context.
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.

This was soon followed by the M8 Harthill bypass but as first opened it extended neither east to J4 nor west to J5.
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.
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).
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
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.

I remember the roundabout in 1998 before it was bypassed.

They will drag you down to their level and beat you with experience.
Here in Ireland, way too many temporary motorway termini to mention and cover in one post (will try to get round to that later in the week) but one that comes immediately to mind was the original Northern terminus of the very short first section of the M1 Dublin to Dundalk motorway which ran for a whopping 5 km from Whitehall to Dublin Airport when it opened in 1985. It was only the second section of motorway to open in RoI after the 8 km M7 Naas by-pass in 1983.
The entire motorway turned a very sharp 90 degrees and ended in an at grade roundabout at the entrance to the airport (which is still there) and that set up was in place from 1985 to circa 2001-03 when a new GSJ roundabout junction was built for the airport where the motorway used to turn to the left - when the M1 was finally extended north to meet the Balbriggan bypass in 2003.

I also used an overlay of the available maps at NLS to show the detail of that terminus on top of a modern map. Looks like a bit of a horror junction that existed until J5 was completed some months later:
The extension of the M8 out to Dechmont also had at an at-grade terminus on Dechmont Roundabout.

Don't forget for many years (around 10 years, until the A406 was completed), the M11 terminated at grade at the Redbridge Roundabout.
Hi Sunil, good to see you posting again. Am I right in thinking it was signed as junction 3?

It was certainly mapped as junction 3, but newer members may not be aware that it was M15 junction 3, not M11.
I'm not sure I'd consider it particularly at-grade though, as the space for the through carriageways was there - much like large numbers of motorway temporary terminii up and down the country.
