Sheesh! Three pages and noone's mentioned Denton Island (M67/M60) yet. :o
On the other end of the never completed M67 is the evidence of the free-flowing junction to connect it to the M1 at J35a

I also know a typical roundabout example here and this monster roundabout which is way to ambitious for what it is.

That would have been the north-facing sliproad for Chapel Town Services, which were never built. When J35a was built it used the south-facing sliproad stubs. They weren't put there for the M67 - no such plan existed when that bit of the M1 was built.

Ah right. That makes more sense. I thought I had read in the article that I sent that that is what they are for but I reread it and they were just suggesting that they could have been used if the M67 was built, not that they were built for that specific purpose.

ow about this: https://www.google.co.uk/maps/@52.53105 ... a=!3m1!1e3
2021-12-01 M6 Toll M42 A38 A453.png
This sketch shows (from the year 1987) M42 J9, the proposed A446(M) (similar to M6 Toll), A38 and A446.

But do we know where the dotted green line would have gone?

Maybe crossing over A446(M) and joining M42?

hi, found this for the a38 minworth island
https://www.sabre-roads.org.uk/wiki/ind ... rth_Island
so looks like the curdworth bypass was planned with the grade separation.

Would be nice if used for the Pedimore access rather than another roundabout on the A38 Sutton Bypass for Pedimore.

From the SABRE Wiki: Minworth Island :

Minworth Island is a roundabout built in the early 1970s as part of the Sutton Coldfield Bypass (opened on 10 August 1973) which moved the A38 away from the urban area. Provision was made for an additional arm of the roundabout to be added which would have been a bypass for Minworth and Curdworth. An underpass at the roundabout would have connected this route to the A38 from Birmingham. A strip of land to the north of Lindridge Drive shows the protected line.

It is Penn Inn, just outside Newton Abbot on the A380.

Does anyone know when the Kingsteignton/Newton Abbot bypass was originally built?
We went on a family holiday to Devon in 1978 and, being a young kid just into maps, I remember going through that junction.
I also remember the odd alignment of the A380 where one carriageway wound its way on the old route and the new carriageway was straight. The next time I drove that road was 11th September 2001 (9/11).

Actually there were 2 bits of A380 where the north and south carriageways separated from each other.

Remember them well. The northbound wiggly bit was the Waddon Brakes section, now partly closed off from the road network, the southern one crossed over the Ideford Arch, which is still there but marked as a footpath.

Odd but not unique: A611 north of Hucknall has a similar arrangement, although nothing like so wiggly:

I only have a map showing the alignment. I don't have anything which shows junction layouts. There would probably have been no junctions between Minworth and the M42.
How would you like your grade separations, Sir?

Or on a proper map, freely available within a large old maps repository on a well-known roads-based website near you...

The junction of the A92 and the B921 in Glenrothes Fife has the bridge ramps partially surfaced for the bridge and on the the B921 west of the A92 there are two junctions partially built i.e the current traffic uses the future off ramps to a circle. Slightly further south on the A92 at the junction with the B9130 at the south end of the Thornton Bypass there is a circle where the approach carriageways on the A92 seem to me that flyunder was proposed for the A92.
Motorways travelled 2019 - M90 - M9 - M80 - M8 -M77 - M73 -A74(M) -M6-M42-M40 -A404(M) - M4 - M5 -M50 -M56 much better so far than last year

Although that appears to be the case the original proposal was a three level stackabout with the A92 from Dunfermline continuing eastwards towards Leven. The current A92 through route at the junction would require a TOTSO.

I think the separation for of the carriageways is solely for sightline reasons
