What is the greatest number of unique lane assignments on a single overhead sign? Keep in mind that multiple lanes that go to the same route number/road name would only count as one. And we're looking just at one direction of a roadway here - if an overhead spans two directions each direction counts separately.
Here is an install that I would be surprised if anything can top: six different choices (https://maps.app.goo.gl/JdoyQXWYR5VT3Acx8) on Sunbury Rd at OH 161 northeast of Columbus. Can this be topped? If there's an overhead with seven or more out there, I'd like to see it.
