Interstate 81 in Syracuse

[amroad17]

I can post an unofficial list.  The list will have a current exit number first and the unofficial mile-based exit number after...

I-81: 1/4; 2/8; 3 NB/9; 3 SB/12; 4A,4B/13A,13B; 5/14; *(I-88)/15; 6/16; 7/21; 8/29; 9/38; 10/50; 11/52; 12/54; 13/63; 14/66; 15/73; 16/78; 16A/82
I-481: 1 SB/82; 1 NB/83; 2/85; 3/87; 4/88; 5/90; 6/91 (Thruway); 7/92; 8/95; 9/97
I-81: 29/97; 30/99; 31/103; 32/107; 33/115; 34/118; 35/122; 36/126; 37/132; 38/135; 39/137; 40/139; 41/144; 42/148; 43/150; 44/152; 45/156; 46/157; 47/159; 48/161; 48A/162; 49/173; 50/182; 51/184; 52/187

I-81's total mileage in New York would be approximately 188 miles after the re-route.

I-81: ... 3 NB/9; 3 SB/12;

File that one under "Today I Learned...". I had never noticed that the half-diamonds at Broad St and Colesville Rd were both Exit 3. Will be good to get them each their own number with the switch to mile-based.

Or at Pulaski, where there are two different interchanges with the same number as well.

Pulaski is basically just two halves of the same interchange, much like I-190 Exit 23 or I-390 Exit 11 without the frontage ramps.

The Exit 3's are almost three miles apart, completely independent of each other, and provide access to totally different areas. They're even facing each other, with each direction having an entrance ramp first, then an exit 2.5 miles later (><), rather than the the traditional exit/entrance configuration (<>), so it's hard to say they're related in any way.

If they number NY 690's exits (to mileage-based, as they will to Interstate 81, Business 81, and NY 481) and continue them after reaching the Interstate 90/New York State Thruway, the exits would probably be like this:

NY 690 Exits

Exit 1: NY 370/NY 31 East
Exit 2: NY 31 West
Exit 5: Van Buren Rd.
Exit 6 (Old 1): Interstate 90/NYST

Interstate 690 Exits

Exit 7 [7A WB] (Old 2): Jones Rd.
Exit 7B [WB] (Old 3): NY 48 North/Farrell Rd.
Exit 8 (Old 4): John Glenn Blvd.
Exit 9 (Old 5): State Fair Blvd.
Exit 11 (Old 6): NY 695
Exit 12 (Old 7): NY 297
Exit 13 [EB] (Old 8): Hiawatha Blvd.
Exit 14 [EB] (Old 9): NY 298/Bear St.
Exit 14 [WB] (Old 10): N. Geddes St.
Exit 15A (Old 11): West St.
Exit 15B (Old 12): W. Genessee St.
Exit 16: (Old 13) Whatever configuration the ramps to Business 81 (and possibly Townsend St.) are reconstructed into
Exit 17 (Old 14): Teall Ave.
Exit 18 (Old 15): Midler Ave.
Exit 19AB (Old 16): NY 635/Thompson Rd.
Exit 19C (Old 17): Bridge St.
Exit 20AB (or left unnumbered): Interstate 81 (former Interstate 481)

There's no doubt it's a pain to get around, but it is much more comparable to a single interchange than the Exit 3's in Binghamton

I-81's total mileage in New York would be approximately 188 miles after the re-route.

According to Wikipedia, it's currently 183 miles, so the reroute would make it only five miles longer.
