NYS DOT could delete this ramp and besides people having to adjust to a new route it'd be no big deal as so few cars use it and other ramps are 1/3 mile or less nearby

As of 2019 the Buffalo Skyway itself only gets around 36,000 cars/day total combined (if not less in 2023 with more work from home folks), down from its peak of 2x (or more) that number when the steel mills and all industry were humming decades ago. That's only ~18k each way or some combination totalling 36k.
Using 2019 NYS DOT estimates:
For the Skyway to Pearl/Seneca off-ramp aka Exit 7, only ~900 cars/day use it.
For the Skyway to 1-190 on-ramp less than 11,000 vehicles/day use it.
The green 'x' marks the development site, adjacent to Doug Jemal's Seneca One Tower in the middle of these Skyway on/off ramps
The yellow circle on left is on and off ramps for I-190 literally 1/3 mile to the North of the development site. The yellow circle on right is on and off ramps for the Buffalo skyway literally 1/4 mile to North of the development site.
