Are any other highways in New York that currently have sequencial exit numbers planning a mileage-based conversion in the near future?

“Is New York State planning to change its Interstate exit numbering system from a sequential system to a distance-based milepost system?
At this time, the Department does not have immediate plans to adopt the mileage based exit numbering system although strong consideration has been given to the idea. The use of both consecutive and milepost exit numbering systems is approved by the Federal Highway Administration. While many states have converted to the milepost exit numbering system, New York is one of several states in the Northeast that still numbers freeway exits using the consecutive numbering system.
Actually, New York was an early pioneer in converting exit numbers from a consecutive order (e.g. Exit 1, Exit 2, Exit 3, ...) to a system based on distance (miles or kilometers). In the 1970's, New York unsuccessfully experimented with the mileage based system in New York City and Schenectady. The milepost system works best when exits are separated by more than a mile. Unfortunately, in some of New York's urban areas, exit spacing is less than a mile.
The Department released a report in January 2003 regarding the feasibility of converting exit numbers on freeways from a consecutive numbering system to a milepost exit numbering system. The conclusion was that although the change is technically possible, it would be quite costly and would have to compete with other worthwhile projects for consideration of scarce resources. Since the Federal Highway Administration has not made adopting the reference post marking system a mandate, but rather an option; New York will likely defer the changeover until it becomes a requirement or additional funding is available to implement the plan.”
As others pointed out, it’s dated. As far as I know, here on Long Island there are no plans to change the exit numbers. There’s a few sign jobs but none involve exit numbers from what I saw.
