It's worth noting that NYSDOT uses the MUTCD standard "round down" method of assigning numbers.  Also that this might not be the only affected location - the PDF with the Region 3 changes (since taken down) had I-690 exit 6 becoming exit 4 EB and 5A WB.

The southbound exit is actually at roughly 39.9.

The numbers @SGwithADD mentioned line up with my site, so I'm guessing that's where they came from.  Ever since I did the re-launch, I decided to split up interchanges like former exit 9 to be more accurate to the mileage.  In those cases, ramps that hit a side road are measured from the "theoretical cross street" where they touch down.

Renumbering old Exit 9 southbound as Exit 39 on Interstate 81 was the right move for NYSDOT. After all, the exit is just to the south of Milepost 40. Does anyone else find it odd they are not signing the old exit numbers with the new exit numbers? Usually, they co-sign the old and new exit numbers to give the public time to adjust to the new numbers.

They are, but better not miss that first sign.

Indeed I did.

Maybe I'm too old these days, and it's less relevant with the proliferation of GPS, but businesses used to advertise as being off of a certain exit, and people could just give one exit number when giving directions to their place. How does that work in a case like this? As an engineer with OCD, I know that it can seem logical to follow rules to the letter, but this is missing a bunch of human-facing issues IMO.

Major construction is beginning on I-490 soon.  Around Bushnell's Basin, I-490 will be reduced to one lane, which is expected to lead to significant congestion (I would go so far as to say that it's Rochester's Carmageddon).  There's advice to "avoid the area", but given that this is the road that one would take to get to the mall or Finger Lakes, that's easier said than done.  This year is going to suck, to the point where I'm considering skipping two family gatherings because I just don't want to deal with it.

Also, if they're doing eastbound this year and westbound next year, what's being done in 2027?

Yikes. Thanks for the heads up. Great to see NY is actively implementing the zipper merge concept, but not with a long-term lane closure here, of all places. When they did Marsh Rd, even the weekend lane closures caused issues, so this is going to create major issues in the afternoon rush hour, to say the least. And Exit 26 barely handles traffic as it is, so any additional traffic there is only going to exacerbate issues on I-490. Also interesting that they'll be able to maintain two lanes westbound, but not eastbound.

One small positive: at least there won't be backups getting on the Thruway at Exit 45 this season

Are they going to close the canal, too?

The press release says "one lane each direction", so they won't.  As for why two lanes next year, note how much wider the Marsh road is than the canal bridge or Kreag.  I'm guessing they can't fit four lanes on one side with the existing bridges, and whatever staging they did for Marsh must be something they're either unable or unwilling to do (it's worth noting that Marsh was done under Cuomo's "Driver's First" policy that eased work zone congestion at the literal cost of making projects much more expensive, a policy that no longer exists as he's no longer governor; also fun fact: traffic impacts on the Twin Bridges similar to what we might have with this project are the reason Cuomo made Driver's First in the first place).

(personal opinion)

Makes sense; I was referring to having two lanes open next year, not the westbound lanes during this year's project.
