CHE: Swiss renumbering

[si404]

Years ago (CHM days), Switzerland had a plan to expand the number of national routes (and renumber some stuff). This didn't happen. However, something similar* will happen at the turn of the decade. https://www.skyscrapercity.com/showpost.php?p=165339190&postcount=3387

These will slowly be signed/resigned as such.

There might be some renumbering of Hauptstrasse too.

*Though, unlike the original, doesn't give numbers to the suffixed routes like A3W

Edit: "CHE:" added to subject

"you are asking too much! the mess in road numbers is one of the few messy things in this country"

I'll wait

Edit, more info: https://www.astra.admin.ch/astra/de/home/themen/nationalstrassen/nationalstrassennetz/neb.html (inconsistent data though)

A53 is now signed as A15: https://www.skyscrapercity.com/threads/ch-switzerland-road-infrastructure-%E2%80%A2-autobahnen-autoroutes-autostrade.510148/post-168093278

No info whether other changes have been implemented. Holding off till I have more info (but moving to the other board and adding the ? icon).

edit: A24 also signed now: https://www.skyscrapercity.com/threads/510148/post-168342565
edit: A11 https://www.skyscrapercity.com/threads/510148/post-168363412

I've renamed both A53 segments to A15 and Superstrada Mendrisio - Stabio to A24.
The "signed" A11 is still A51 and will remain as A51. N11 is concurrent though.
The rest is still quite unclear.

It seems that A10 and A19 and other routes appeared in addition to what was announced... I need to wait and see...

Legend for my notes on the map attached:
Changed with https://github.com/TravelMapping/HighwayData/pull/4016
Was already in HB as it should be
Not relevant - no road existing
No evidence, not changed

A17 and A23 are indicated on OSM now.
A press release confirms that they should have been signed by summer 2020 (also A15 which I had already added)

I'm not sure about A20. There is a press release from June 2020 about road works. The route is called A20. wikipedia confirms it but not yet GM nor OSM. GSV and mapillary don't have pics from 2020. Not yet added!

Updated map for the north of Switzerland attached (no routes in lightblue).

The 2nd A23 at Müllheim and three A20 segments are indicated on OSM now. Added, new routes in lightblue on attached map: https://github.com/TravelMapping/HighwayData/pull/4524

Open issues:

- Does A20/H20 extent on 2-laned road up to A1? unsigned H182 now
- Is H20 concurrent to A20 west of Neuchatel or parallel? OSM has just changed it to the parallel road but I have no evidence.
- Is H5 east of Aarau H1R now? OSM indicates H1 now but the H1 already exists on a parallel road which is still indicated being H1.
- What should happen to A4 north of Schaffhausen, downgrade to eursf route?
- Does H25 Appenzell exist? There are unsigned 3-digit H routes and routing is not clear.
- 2x H6 south of Thun, still unsigned H223 and H509

- What should happen to A4 north of Schaffhausen, downgrade to eursf route?

It is definitely no longer A4 but Kantonale Autostrasse Bargen - Schweizerbild (new eursf route now). wikipedia and OSM indicate H4 on the parallel route through Merishausen now. Changed: https://github.com/TravelMapping/HighwayData/pull/4653

[michih]

Open issues:
- Is H5 east of Aarau H1R now? OSM indicates H1 now but the H1 already exists on a parallel road which is still indicated being H1.

First A1R indication is visible on OSM now. It was changed just five days ago and does only cover a very short segment. 2014 GSV shows motorway signs at H288 interchange and at H24 interchange. The official toll map extends the toll sections to next junctions west / east of there. A1R is also used in online traffic reports. There is no info on the autobahnen.ch forum thread but the forum has very little active users.

I'll keep it as H5 till I get more info.

OSM was updated (because of my note). Route added to HB: https://github.com/TravelMapping/HighwayData/pull/4687

I missed the renumbering of A4a Zug anyhow. It is also A14 (Zug) now.

I've been to Switzerland to re-clinch the chea system. Of course, I did it
A17, A20 and A23 (Müllheim) are indicated on mile posts but not on direction signs --> 
A1r and A24 are not signed in the field. I had added them to chea because they are indicated on OSM as such --> 
H223 is also not signed in the field and has expressway signs only -->

A1r, A20 (sections west of Neuchatel) and A23 (Müllheim) have motorway signs. I don't remember about A17 and A24 but think that they do only have expressway signs.

Should I move H223 from eursf to chea nonetheless?

Open issues:
- Does A20/H20 extent on 2-laned road up to A1? unsigned H182 now

Not at east end to A1 but at west end up to A5. I've merged the two A20 routes including concurrency to A5.

I've also extended the A20 (Le Locle) to Le Locle as it is signed as such on km posts. The motorway starts / ends at the interchange in-between.

- Is H20 concurrent to A20 west of Neuchatel or parallel? OSM has just changed it to the parallel road but I have no evidence.

H20 runs parallel.

Open issues:

- Does H25 Appenzell exist? There are unsigned 3-digit H routes and routing is not clear.
- 2x H6 south of Thun, still unsigned H223* and H509

OSM and German wikipedia indicate the Wimmis feeder (to motorway exit 18) as unsigned motorway now (was A6). The Mülenen feeder (former H223, to motorway exit 19) is indicated as non-motorway A6. wikipedia's A8 article indicates, that the A8 section between exit 18 and exit 19 is A6 now ("Die A8 beginnt bei Spiez (bis 2019 bei der Verzweigung Lattigen, seither Teil der A6)."). The latter is not confirmed by OSM.
GM, English and French wikipedia still have the old configuration.

An official map is indicating the Wimmis feeder as Nationalstrasse N6W and the Mülenen feeder as N6. As Si mentioned in the first post, the change was due to changes to the Nationalstrassen law. When I select the actually signed Hauptstrassen, Wimmis feeder is unsigned and Mülenen feeder is A6 as well as the section between exit 18 and 19, i.e. just like German wikipedia is indicating.

GSV is from 2013/14.

I need to field check the actual signposting...

[michih]

LOL, there are some mapillary pics from August 2023

A6 is signed westbound in exit 19 where the recent pics begin. A6 is indicated to continue onto main route and onto Wimmis feeder. Wimmis feeder is still signed as A6.

So, I thought that minimum the A8 to A6 conversion did happen but the sign was already in place in 2018. The law only changed in 2020

Keep as-is?

[michih]

Open issues:
- 2x H6 south of Thun, still unsigned H223* and H509

The now southern N6 - also indicated on OSM -, i.e. H509 (3-digit Hauptstrassen are always unsigned) was still unsigned on January 2022 mapillary since no road numbers are indicated at all down there

[michih]

I've field-checked both ends of "N6", i.e. H223's north end and H509's south end. Both are not signed as "6" something. I'm closing the thread (after almost four years) for good now.
