Ah, ok. Unfinished initial revision.
Internet's been down for three days because of the ice storm here, so it'll be a bit before I can fix this x.x

WB 14
WB 15

As NH 12 and 19 wholly encompass the three named expressways in Tier 1, I am considering having them pulled in favor of the NH and AH systems. However, the Acharya Jagadish Chadra Bose Flyover/Parama Flyover expressway could be added.
Headache: Lack of street names in any of the online maps along the southern portion of NH 12. May be endemic in other routes as well.
Reaching out to a friend in Kolkata as well as to my brother-in-law to see if this is in-the-field accurate. I did note the lack of street signs when I was in Burdwan a year ago.

I spoke with my friend in Kolkata; she said that all roads are supposed to have names.
My brother-in-law said that Google's the go-to for online mapping in India.

Sigh

Google certainly has the most accurate street traces, moreso than OSM, but they are missing so much data. And no GMSV at all.

Ok, NH 12 update.
I've done the initial revision from the southern terminus at the Bay of Bengal into Kolkata. Points have been added at approximate locations along the route per what to be access points into various villages etc, using villages and towns as the labels if the online maps don't have any at the moment. Google has had good handful added, however, which has helped.

Just to complicate things, Google claims NH 12 and WB 1 take different routes through/around Kolkata than the other maps do.

Thankfully, this is the longest route in West Bengal, longer than even the circuituous state highways.

NH 27's a menace. Not only does it have the border hops between Bihar and West Bengal that put BC 97's with British Columbia and Yukon to shame (and by extension, NT 5 with Northwest Territories and Alberta), but NH 27 also has 6 rapid fire border hops between Assam and Meghalaya.

NH 16 has a few between Tamil Nadu and Andhra Pradesh, NH 18 and 218 both with Jarkhand and West Bengal, and NH 717B has a good handful of switchbacks crossing from Sikkim into West Bengal.

27 and 717B may wind up with sequential segment naming.

So. How do we deal with state routes that dip into different countries?

OSM says WB 12 border skips into Nepal a few times. Google even agrees on at least one instance. Mapquest and RMN agree... in a different location.
Bing avoids it all by keeping WB 12 all in India.

Would this need to be handled any differently than situations like where NY 17 dips into Pennsylvania for a bit?  I think indwb would then have pieces in NPL, allowing the _con.csv file to keep it a single route.

Like German Bundesstra├čen through Austria, Belgium or Switzerland?

This might be worth discussing in a different thread, but while working on NH 12, I have two AliRd tags. The second one is called 'Alipur Rd', and if memory serves, should be AliRd_Kal for the city.
But in this instance, using 'AlipurRd' uses less characters. I'm putting in AliRd_Kal as an alt label so I can easily switch it if needed, but this seems that holding hard and fast to the three or four character limit per word for a tag seems silly.

NH 12's initial revision is done.
OSM and Google disagree on routing through Kolkata and Malda, deferring to OSM here.
Placeholder shape tags for the future Dakola bypass, as well as shape points on a Bihar border skip Google says that OSM doesn't; route is split for border crossing OSM indicates that Google doesn't just east of NH 27.

Next: NH 14
