NY: NY 17 by Hillburn and its concurrencies with I-87 and I-287
« on: September 30, 2016, 06:41:03 pm »
So I had always presumed (since I clinched this part of I-87/NYST back in 2009) based on signage that NY 17 had a concurrency with I-87/NYST from I-287 to NY 59 (Exits 15-15A).  However, I have just noticed that it is shaped as going around Hillburn before NY 17 SB goes onto I-287 SB to head into NJ.

NY 17 SB signed as going onto I-87/NYST at Exit 15A


From the road that NY 17 may or may not take to go around Hillburn (this is still at Exit 15A this road is signed as "TO NY 17" from its intersection with NY 59)

At what may be or have been the NY 17/NY 59 intersection: Looking at NY 59 EB,
Looking from NY 59 WB,
Looking from what may be NY 17 NB

Also both directions are posted on I-87/NYST (SB, NB)

I am unsure if this affects the NY 59 file.  I hope the many GSV links are not confusing.

The 2011 NYSDOT Traffic Data Report lists a NY 17 overlap with I-287 for its last 0.11 miles before the NJ line.  It does not indicate an overlap with I-87/NYST.

Just double-checked NYSDOT shapefiles, which confirms what Jim mentioned from the traffic data report.  NY 17 officially follows the old highway around the south and west side of Hillburn (including the southbound on-ramp to I-287), despite the fact that one must briefly take the Thruway to follow northbound NY 17.

Personally, I will probably just keep that part of NY 17 considered as clinched (since traffic intending to follow NY 17 NB must use the Thruway) and put a note to myself drive that other section whenever I finally clinch other stuff in the area.

For the record, these street blades that say "RT 17" seem to be the main posting here.

At the very least, I need to resync NY17Bin@I-87(15) to I-87@15(NYST)&I-287@15(87), to properly count the southernmost segment's concurrency with I-287 into NJ. This will happen in Part 2 of a big NY cleanup update.

I still think, based on what Markkos1992 found, that moving NY17 is worth looking into. But that does bear some discussion, and I'm kicking that can down the road for now.
