Swiss renumbering
« on: December 31, 2019, 02:31:15 pm »
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

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

I'll wait :)

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

https://github.com/TravelMapping/HighwayData/pull/4016

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.

and
https://www.autobahnen.ch/index.php?lg=000&page=001

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

https://github.com/TravelMapping/HighwayData/pull/4218

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

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

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.
