NY: US 219 I-90 Points

[Markkos1992]

I-90_S and I-90_N should probably be edited at minimum to I-90_W and I-90_E.

If there's no overlap, you use directions of 219. No change is required.

The dual carriageway setup is a bit borderline Alanlandian, but I'm with neroute2. Marking solved.

Rethinking it, I was leaning towards suggesting using the Thruway exit numbers for those points as weird as it may look.  It could be considered complicated since they are NYST numbers instead of I-90 numbers.

It could be considered complicated since they are NYST numbers instead of I-90 numbers.

And also that they are both 55 (though the southern/western one is 55A in the I-90 file).

I-90(55A) and I-90(55) would work, as would NYST(55A) and NYST(55).

As defined by NYSDOT, there is no overlap between I-90 and US 219. US 219 runs along the outer roadway until said roadway merges into the main Thruway lanes. It's not a concurrency and the interchange with Ridge Road is with US 219. Thruway Exit 55 is really a pair of partial exits with US 219. The way TM currently shows this is close to accurate.

I-90(55A) and I-90(55) would work, as would NYST(55A) and NYST(55).

Given the fact that there is no concurrency, these labels make the most sense to me.  Two I-90 exits where you can get on/off US 219, correct?  And avoid the N/S vs. E/W confusion.

I had been a bit hesitant to use a fudged Two separate interchanges numbered... suffix in cases like these (disambiguation or multiplexes)...
(Compare ME26 multiplexing I-295 between Exit 8 and... also Exit 8.)

But another read thru the manual suggests that exit numbers are the right way to go, suffixes notwithstanding:

If an exit numbered highway is a cross road twice, exit numbers in parentheses can be used to distinguish them. Avoid using two designations and a parenthetical suffix in the same label.

If a non-exit-numbered highway is a cross road twice, add an underscored suffix. The direction letter refers to the relative position of the intersection along the route whose file is being made. US90_S is the southern of the two US 90 junctions along US 25, which runs S-N.
