Near me, New York State Route 146 (which was used as an example elsewhere) wanders. There's a stretch of a few blocks (https://www.openstreetmap.org/way/5640056 and neighbouring ways) near a shopping mall where it's 'Clifton Park Boulevard', but nobody knows that name because there are big overhead direction signs that carry only the route number. On either side, it's called just 'State Route 146' and has no other name. The post office prefers '806 [State] Route 146' as a building address, but '806 Clifton Park Boulevard' is deliverable. Farther south/west (146 does not have consistent cardinal directions!) 146 is co-aligned with city streets. Balltown Road ( https://www.openstreetmap.org/way/338036383 etc.) is signed 146, but nobody calls it anything other than Balltown Road. Addressing mail to '1617 Route 146' would likely face delays and misdeliveries because it woiuld be ambiguous: 1617 Balltown Road https://www.openstreetmap.org/way/689572012 fronts on Route 146, but so does 1617 [Upper] Union Street https://www.openstreetmap.org/node/804483895 , and I haven't done the address points but there's likely a 1617 on Brandywine Avenue https://www.openstreetmap.org/way/5646367, Hamburg Street https://www.openstreetmap.org/way/53306647 , or Carman Road https://www.openstreetmap.org/way/135620106 Beyond Western Avenue, there's a brief stretch https://www.openstreetmap.org/way/159115284 where 146 has no other name. For a few blocks, it follows Main Street, Maple Avenue, and Township Road through the village of Altamont. It retains the 'Township Road' name west to the county line, but the situation is fuzzier. Mail will be addressed to '1234 Township Road' but a local directing you to a house will tell you to follow 'Route 146' because there isn't much signage with the formal name (There is some, so 'unsigned_name' isn't appropriate.) From the county line to the terminus at Route 443, 146 goes back to having no other name. In these cases, I don't expect a geocoder to associate a building automatically with a nearby street, and place the full set of address fields on every building, entrance or other address point. My preference would be to put 'New York State Route 146' as the 'name' of the route where it has no other name, or as 'alt_name' if it has another name but the locals favor the highway name over the formal name. I think that pairing 'ref=NY 146' with 'State Route 146' is too much to ask of a geocoder, while asking it to match a partial string ('New York 146', 'State Route 146', 'Route 146' or even just '146') is pretty much all in a day's work for full-text search engines. Nevertheless, the last time that I raised this issue, there was an overwhelming consensus that 'Route 146', in the stretches where that is the only name, is an unnamed way. For that reason, and quite against my better judgment, I've been sporadically deleting `name="New York State Highway 146"` when it appears and replacing it with `noname=yes`. I've been doing this only when I happen to be working on a segment of the way, and only when I happen to think of it, rather than systematically. This lackadaisical approach is probably in part because I still don't agree with the consensus, merely defer to it. Some side notes to remember: It's worthy of note that the US has multiple route networks overlaid, with reuse of numbers. Where this happens, generally speaking, the signs have distinctive colors and shapes, but it is necessary to keep the authority as well as the route number. There are crossings (e.g. https://www.openstreetmap.org/#map=15/43.0047/-76.7002) where that's significant - note the two routes numbered 90. It's uncommon - for instance, counties often simply skip over the numbers of state routes that traverse the county when assigning county route numbers - but it happens. It also is worth noting that the jurisdiction cannot always be deduced from boundaries. https://www.openstreetmap.org/way/666565376 is signed 'NY 120A' even though it is in Connecticut. https://www.openstreetmap.org/way/46691563 is signed 'Vermont 279' in New York, although the small reference markers on the shoulder (these are unreadable at speed, and where mapped in New York are unsigned_ref) show '915G'. Finally, 'State Highway', as far as I know, is not an official designation of any road in New York: the state DOT uses 'State Route' consistently for its numbered routes. Pedantically, there's also 'State Reference Route' for various numbered routes that are not prominently signed but are state-maintained. Most of these are either named (e.g., 'Taconic State Parkway') or connector routes that often bear signs like 'TO NY 5' -- 73 de ke9tv/2, Kevin
