Files are in place on GitHub, but not quite ready for devel.  @Bickendan and others who have dealt with split countries split by region outside of the US and Canada, please take a look at where I put things and make sure it looks reasonable.

They can go to devel once we have one more .csv and all three _con.csv files.

Looks fine.

I've made the _con.csvs, per the routes as currently there, as well as making the missing .csv, and fixing the others (region is "IND-WB", rather than "WB"). I've added the systems to systems.csv, and ran a datacheck so it works. @Bickendan ought to download and maintain those files:
https://github.com/TravelMapping/HighwayData/blob/master/hwy_data/_systems/indah.csv
https://github.com/TravelMapping/HighwayData/blob/master/hwy_data/_systems/indah_con.csv
https://github.com/TravelMapping/HighwayData/blob/master/hwy_data/_systems/indnh.csv
https://github.com/TravelMapping/HighwayData/blob/master/hwy_data/_systems/indnh_con.csv
https://github.com/TravelMapping/HighwayData/blob/master/hwy_data/_systems/indwb.csv
https://github.com/TravelMapping/HighwayData/blob/master/hwy_data/_systems/indwb_con.csv

I've added 'x' banners to the asiahp files (and I'd imagine they'd just be replaced by the indah files in the asiah system) in West Bengal - because otherwise it throws a hissy fit as there's two routes with the same name. This is a heads up for when this redo extends to other states.

I'll grab the fixed and added .csvs when I get on my laptop.
I just noticed the named National Expressway routes in the browser; as the Durgapur overlaps 100% with AH1/NH19, the Belghoria with AH1/NH12, and Kona with NH 12, should I worry about these (I feel like it'll stray into can of worms territory with other regions [ORH cough])? I don't want to stir that pot at the moment.

Well... great. I was drafting out NH 27's border hopping between Bihar and West Bengal, noticed the border shifted on a zoom level change on OSM, so went to compare with Google. Google's Bihar/West Bengal is completely different, showing only two border skips compared to OSM's seven.
Bing shows four, Mapquest only one, and RMN also only one.

I don't know who to believe here.

I'm down to the last NH in West Bengal -- 316A, and I'm finding no evidence outside of the Gazette of India article Wikipedia cites. It's supposedly a NH 316 spur mostly in Orissa/Odisha (the official language there is Odia, not Hindi or Bengali, and my friend in Kolkata says it's Odisha) that terminates with NH 116B in West Bengal. The itenary makes absolutely no sense, however, suggesting it's a route that first bounces west of NH 316 then north of NH 16, then back to the south of NH 16, wedged between 16 and the coast, while 16 isn't that far inland.

OSM has 116B heading west of Dhiga, WB, into Odisha and terminating soon thereafter, with WB 4 overlapping in WB and OD 57 in Odisha.
Google has no NH west of Dhiga, instead having OD 57 entering WB and ending in Dhiga (this itself is incorrect; WB has no state highway above 15).
Bing doesn't show 116B at all, but does show WB 4 running to the WB/OD border (WB State Police route descriptions agrees with this).
Mapquest agrees with OSM's routing, just not showing the SH overlaps.
And RMN agrees with OSM and MQ.

So with that in mind, no 316A.

The only truly unresolved question is how none of the online maps agree with each other when it comes to NH 27 and the Bihar/WB border.

To draft:
WB 1
4
4A
6
7
8
10
10A
11
11A

In case anyone has a chance to investigate, I put lots of updated files from @Bickendan into GitHub and ran a site update, but this led to many errors.  I'm commenting out the system to get an update through for now.  Could be some misnamed or misplaced files, could be some fields missing in the csvs, but I won't have time to investigate and fix right away.

The unrecognised region issue is because the ISO 3166-2:IN code for Bihar is BR, and thus our code is IND-BR, not IND-BH.

The Duplicate main list name issues are a lack of values in the 'Abbrev' field.

Not an intuitive ISO code, but I'll get those fixed, including in the tag labels.

Ok, I'll fix those up at lunch.

BihaR is no different to IowA, ConnecticuT, VermonT or VirginiA.

Is BH signed on roads?

Doesn't look like NH was reactivated.

Initial drafts for IND-WB have been finished. Once they're live, I can start refining the files and hunting down appropriate labels for every tag (less of an issue for the AH files and the routes that overlap them).
Nightmare routes for WB will be NH 10, 110, 710, 717A, and WB 12, as they all ascend into the Himalayas north of Darjeeling and are switchback hell (Sikkim's going to be fun -- might do that next to get it out of the way).
