I did mean Barton sorry. But yes if you look at the marker posts and DLS they are not the same as everywhere else so they'd all need converting to the standard format rather than the fractions that are presently in situ.

The "fractions" are actually kilometres and tenths from Barton, e.g. 3/4 means 3.4 km, and the D possibly means County Durham. But the numbering system used between Blyth and Barton is already different from the one used in the south.

On a tangent, what's the arrangement on the A30 in Devon/Cornwall?

Off the top of my head I believe the zero point for the A30 expressway sections is Land’s End.

Of course you do know this section has been numbered the M90(A) as its a motorway with A road characteristics.......

There is talk of possibly making it M90 the whole way, but that is still in discussion. Issue is with the A90 coming out of edinburgh

Why didn't they just put C&D roads on that section? Problem solved
How about some more beans Mr. Taggart?

Or open the bus only slips to regular traffic? Or send non motorway traffic off at the B924? Either option provides a more cost effective solution.

I would open the bus only slips to regular traffic. The B924 is very narrow in the centre of South Queensferry, and it includes a cobbled section west of the Forth Rail Bridge.

A similar question to my A30 marker post post. See my post. The spacing of the markers is not gospel it seems, and if errors are found they just leave it as it is. Perhaps the old 1/16th of a mile posts were just re-labelled and left on their old positions

That wouldn't have worked here either - because the road was extended at the Southern end, so the zero point would have been at the old junction 1, and the road now extends several miles beyond that point.

At last we have an atlas that shows the section of A90 between 2 sections of M90 correctly. All of the 2018 road atlases showed this 2 mile section of road incorrectly as the M90. The 2019 Collins road atlas of Great Britain correctly shows the section between junctions 1 and 1a as the A90. Unfortunately it also shows the A9000 over the old Forth Road Bridge as a Primary Route (coloured green) which I believe to be incorrect. Does anyone know whether the A9000 is Primary or not.

The A9000 is not a primary route, all the direction signs to it are white, it is though still a trunk road.

This all sounds a right bodge to me. I dont know the area at all but was looking at it on Goggle Earth th other day and it struck me what an odd set up it was, all (to my eyes) for the lack of a sliproad or C/D road linking the WB A90 with the old A90 towards the old bridge. if this existed non motorway traffic would have an escape route onto the old A90 and the new road could be motorway. Same in reverse if that sliproad were open to all non motorway traffic not just buses.

But is suppose this is all too logical for TPTB!

While we are on the subject of odities in this area, is there any reason, other than historic that the M8 and M9 should still meet on the A8, leaving the M8 with a spur, instead of the M9 starting on the mainline M8 further south, thus eliminating the spur?

Used the FRB on my way home from Arran last Monday
If I'd known the East walkway was shut in advance I'd have gone down the ramp from Echline as you can get onto the walkway from the road approach there but didn't find out until I was at the underpass...

The problem of being on the wrong side for my destination has been "nicely" fixed by a pedestrian crossing over the roadway to the Inverkeithng side once you make landfall!

Never got why they just didn't build the M90 around the West side of Dundas Castle. Would have saved the massive corner, made the route slightly shorter and solved a stupid problem like this.

Quick look on Google maps shows reasonably flat open fields, so there's no obvious reason why the road didn't go that way

The A90 coming out of Edinburgh would not have been very well connected to the M90 had that been the case. Traffic from the north western side of Edinburgh would have ended up using a short stretch of the A904 to access the new crossing. Going back to the days of the A8000, there was already a partially complete motorway link to Queensferry in the form of the M9 spur - so it would have been pointless to build a completely new motorway rather than just extending the existing one.

Going North up the M90, after passing Kirkliston, does anyone know why a right-turn isnt provided onto the A90 towards Edinburgh? Providing such would seem to be a good idea, as some traffic appraoching Edinburgh from the West could avoid the possible congestion at the Gogar and the one to the south (Gogarbank?) interchanges?

I’d imagine cost and the fact that there didn’t used to be access from M9 southbound at j1a of the M9 - that’s relatively recent. - in the meantime those of us who commute in from west lothian tend to cut through kirkliston and use the Burnshot road, or up through winchburgh on backroads to Newton and join the M90 there depending on what waze says is the quickest way

The new 2020 A-Z road atlas shows this small section of the A90 correctly. The last 3 editions (2017, 2018 and 2019 all showed it incorrectly as the M90

I usually buy the AA road atlases every year and as of the 2019 edition the section of the '90 between J1 and J1A is still shown incorrectly as the M90, so hopefully a positive sign that this will be rectified in the 2020 AA edition as well!
