Furthest away control point for major cities

[Roadgeekteen]

Atlanta is posted 652 miles away on I-75 in Ohio.

The farthest city posted from Atlanta is Tampa, but that's not the farthest that Tampa is posted because Tampa is also posted on I-75 in Ohio.

Although the Ohio examples are what I would call novelty signs that are not strictly *control cities*. And Tampa in Atlanta is similar but is posted for the purpose of guiding through traffic along I-285 away from downtown Atlanta.

For standard control cities, which includes also being featured on mileage signs as well as being featured consistently on directional signs: Atlanta is the control city from Montgomery, and similarly the farthest control city from Atlanta is Montgomery.

For I-75, isn't there a Miami sign in Michigan?

That's on US 41 in Cooper Harbor at the far northern end of the state. Quite a ways from I-75.

MSP: Madison

Interesting how MSP signs Madison, but Madison does not sign MSP despite MSP being much larger. Madison instead uses Wisconsin Dells for the I-94 corridor, which I think is the right choice. And most of the control cities in southern Wisconsin are in place to help people from Illinois anyways. But if I was MSP I would use Eau Claire, Milwaukee, or even Chicago over Madison.

So lo and behold I was out in the east metro today for the first time in months. They changed the control city to Eau Claire for 494/694 traffic at the 94 interchange in Oakdale, though it's still Madison on 94 eastbound proper.
