Hiway 9 South of Lake Placid NY - Clearance Issue?

Sometimes, the clearance "issue" can be the clearance on the far right side of an oval shaped tunnel or bridge and you will be ok if you keep to the left. The local signs are probably a better guide than a map or gps.

According to my truckers atlas the bridge under I87 is low clearance at 12' 9''. Doesn't list anything else right around there.

I just drove that run a week ago with a 21' hybrid with 10' height/ 8' width. I do not recall any height clearance issues, however they are doing bridgework on 9N in Au Sable Forks. The bridge is down to 1 lane (alternating traffic). It is very narrow and I could see it being an issue for a big 5th Wheel especially on the side that has the T intersection. I found it quite tight with my HTT.
I do faintly recall seeing signs about that, but I think they are referring to width clearance, not height.
