Hi,

Unfortunately I've had to revert your last several edits because they go against the current state classification guidelines. 

Since 2021, there has been a push to reserve motorway and trunk for the most important roads, regardless of how many lanes they have, whether they are a freeway or not, etc. For example, NY-384 through downtown Niagara Falls is trunk even though it's a surface street, since it's the best route to use to go over the Rainbow Bridge and get to Canada. In contrast, the LaSalle Expressway and Niagara Scenic Parkway are not important long-haul routes, and would be classified as primary with expressway=yes to denote their upgraded construction.

In New York State, classifications are mostly based on the ACC codes provided by the NYSDOT. For more details, please see this page: https://wiki.openstreetmap.org/wiki/TMP-Proposal:_New_York/Highway_Classification

Again, I'm sorry to have to revert your work. Please don't hesitate to reach out if you have questions or comments.

Best,
John
