Roads that can't be driven end to end
|A8||is another unless they moved it onto Clyde Place when Kingston Street became one way- buses Eastbound- and that is just in Glasgow- you certainly can't do it along Shandwick Place last time I visited.
The A8 still goes up Princes Street in Edinburgh, however it is now restricted (with the exception of a couple of junction crossings) to buses taxis and cyclists only (also delivery vehicles overnight).

|A814||too however it is a bit different in that there are two A814s with a half mile between them- although you could get to the end on 1 of them you don't drive the complete A814.||flyingscot|

- Not if the ferry is still operational! --Chris Bertram
Are some only drivable fully in one direction due to one-way systems? I'm thinking of the A6 in Penrith, for example - I don't think (although I'm not certain) that the northbound route is A6. The route south through the town is the original A6, at any rate. --Helvellyn
- The A4 can only be driven westbound through Reading due to one-way systems. Eastbound you have to use the A329. --User:DavidB

But Google shows the A90 rerouted via Melville Street Caught me out because a) I hadn't been in Edinburgh for yonks. b) was trying to drive the A90 from central Edinburgh back to Dundee and following the Astra's Satellite Chavigation btw if it has been rerouted then the wiki needs updated --novaecosse
A26 Tonbridge. The road going northbound disappears at the A21 junction which only has westward facing slips. The A26 reappears at the next eastward junction on the A21. Not sure if this is a multiplex but in either direction there is no opportunity for A26 traffic to multiplex. Strange! --Fluid Dynamics
- Strange indeed. I'd say that counts. So does the A182 for the moment, where there is a multiplex with the A19. The northern junction by Dalton Park has full access, but the southern junction at Easington has no access southbound to the A182 from the A19, so you can do the full stretch in one direction but not the other. I say "for the moment", as I understand there are plans for a new link road that would divert the A182 and complete the gap. --Chris Bertram
For a logical reason I'll say the A4040 because it has no ends, it's an ouroboros! I'm certain there are other examples of pedantic roads that don't have a linear purpose like the A3078 which resembles a noose at the coast leaving only one 'genuine' end. Or have I disassumed? --Halstead
- For that matter, you can also have the A888. --nowster
- Perhaps we need a separate thread for circular roads. I'll see your A4040 and raise you an A4540 and an A4150. --Chris Bertram
- A different topological structure which permits a journey over the entire length of the road (there are two "odd nodes" in mathematical puzzle-speak) would be the B4564 from its junction with the A4093 between Blackmill and Tonyrefail, up and around Gilfach Coch and back to a T-junction with itself. --Paul Townsend
- Are we discounting roads with spurs? The A664 has two. --nowster
B4419 runs through Caernarfon through some changing route to the Quay...and then re-appears on the south side of Anglesey. No ferry and never has been to my knowledge- built for one that never began? Unless you have a DUKW and take it across the Menai Straits...? --worcsfan
The A182 going south. It multiplexes with the A19 except that where it leaves the A19, there is no off slip to get to it! You have to take the A1086 and B1283 to do a loop around to reach it.--Mark Hewitt
A1036, as it forms a circle in the middle...
A19, not just for the reasons already stated, you have to use part of the A1036 in York!
B1248-If spurs count!
I think that's all round here! --Mattemotorway
Not anymore, now that Kingsbridge has been sorted out, but it used to be impossible to drive from one end of both the A379 and A381 to another, thanks to the rather strange multiplex with a B road, with the B road taking priority!

I've often questioned whether that is still correct and it continues to the other side.
Google Street Map shows the A741 as terminating in the centre of Renfrew, however the Ordinance Survey map shows it as continuing to the Renfrew Ferry and then running the short distance on the north side of the Clyde up to the A814 Dumbarton Road. So it seems safe to say that both parts are still the A741.
The full route was motorable up until the mid 80s. With other routes being available (M8, Erskine Bridge, Clyde Tunnel) which provided a link between the Renfrew and Paisley areas and the north side of the Clyde, and also due to a decline in vehicle useage, the vehicle ferry was retired in the during the 1980s and is now a floating restaurant in the Anderston area of Glasgow (). SPT then stepped in to maintain a link between Renfrew and Yoker with the current pedestrian-only ferries, Renfrew Rose and Yoker Swan.
A photo of the old Renfrew Ferry on its last day in service can be seen here:
And of course there was also the A625, until it was rerouted a few years ago.

Can we just make it clear that multiplexes DON'T count? So, in Mattemo's A19 example, you can legally drive the entire length of the A19 in one go, despite having to use other roads to reach the next stretch.

I think that's right, otherwise every mutiplex in the country will end up on this thread.

In Ilfracombe, is in two parts, which were obviously meant to link up, so whilst half of it is a standard residential road, it is cut in two by a dirt footpath.

I can better that! in Lower Earley is in three separate parts. The first gap is due to housing development, the second is due to construction of the B3270 Lower Earley Way leaving the bridge over the M4 with no vehicular access from the northern side.

Does the A259 dissappear in the middle of Eastbourne too?
agc2070 : Tue Jul 28, 2009 21:59
Actually, in the 1922 listings, the A259 disappeared for part of its journey - between Newhaven and Eastbourne if I'm correct (I might be wrong). In the gap it was the B259, so back then you definitely couldn't drive the road from end to end.
Jonny A46 : Wed Jul 29, 2009 11:09
How about the A417 at Cirencester? If you tried to do the full A417 in either direction you'd end up going towards Swindon.

We're trying to find roads where some sort of obstruction is in the way, such as the footbridge in the OP.
The case of the A417/A419 in Cirencester is an interesting one, and the maps and signs don't necessarily support one another. IIRC, as you approach the A429 junction on the A417 from Gloucester, ahead is signed as the A419, but the OS 1:25000 says it's the A417, with the A419 only taking over after the merge from the old by-pass. By this time you have already passed under the continuation of the A417 towards Fairford and Lechlade. So I guess that counts, as you can't leave the A417 at the A419 merge.
Chris Bertram : Wed Jul 29, 2009 13:51
If I recall correctly, the non primary A417 crosses over the trunk A417 just east of Cirencester without a junction. So you can't drive the A417 from end to end unless you like driving off bridges.
As far as signs on the ground go, it's definitely A417 heading northbound after the A419 splits off, though I'm not sure about southbound.

- middle section never built.
- built in two sections, separated by a railway line, and linked by a footbridge. Today, a steel fence prevents vehicular access between the two section at the former line of the railway, with a gap provided in the fence for pedestrians.

What about the B845, which goes northward from Taynuilt to Barcaldine – or would do but for Loch Etive getting in the way, across which there is no ferry service.

The N11, at certain times of day; since Monday part of it becomes bus-only at times.

The A235 is now in two parts and North End, Croydon is pedestrianised and impassable. The detour round the town requires several different roads to get back to the other half. It cannot be said to be a multiplex.
multiraider2 : Wed Jul 29, 2009 23:32
I've mentioned a few on the road trivia thread, but since then I think most have had the isolated part changed to a new name like Back Lane in Ham which is now Wiggins Lane. And when I was on a weekend course in Windsor like many tourists do daily I had an old map (this was in 1982) showing the road bridge and came to a sudden halt when I wanted to cross over to the north side. They make you drive a few miles west on the trunk road now which is a 'royal' pain (sorry!).
I'm not sure what the road designation is in Guildford but they've done the same there with the bridge by Debenhams although there is another you can still use a few yards away at least unlike Windsor.

- are all possible at certain times of day. I was really thinking of permanent situations. Having looked the A741 up on the Wiki, I can see that qualifies unless a vehicle ferry were ever to be reinstated. --Chris Bertram
