[Talk-us] downgraded highway classification in US

[Richard Welty]

there are some notes in the Wiki about downgrading state highways
to tertiary if they don't connect up to other secondary roads at
reasonable intervals.

in the spirit of this, when i encountered a county route in Rensselaer
County that was a stub that only reached a couple of houses and
a trailer park, i decided to try tagging it as residential, but included
the ref tag for CR 9; the road in question is Lauster Terrace. As you
can see here, Mapnik doesn't handle ref tags on a residential road
particularly well:

before i rush off and open a mapnik ticket, i thought i'd broach
this question: how far should we downgrade routes in these
circumstances? was residential too far in this case, should i have
stopped at unclassified?
