So, I did a little bit of research today. Thanks to my CAA/
AAA TripTick, Google Maps, and a different website for each state, I think I've got the tolls figured out for my route!
(all info is subject to changed, based on best info available at time of research)
Peace Bridge - $3.00
NY State I-90 - $3.15 (you get a ticket that shows your distance traveled to calculate the toll)
West Virginia US-19 - $0.40
West Virginia I-77 - $2.00
If you go through Charleston WV, the toll would be $6 along I-77, and you wouldn't have the US-19 toll.
Figured I'd share this, just in case anyone else can find it useful.
