Furthest-apart pairs of freeway exit signs for the same town on the same freeway

[Dirt Roads]

The longest stretch in North Carolina is for of all places, Chapel Hill (which is located right alongside I-40).  For I-40, there are three consecutive exits marked for Chapel Hill (Exit 273, Exit 270 and Exit 266) plus Exit 148 in Graham (NC-54, which is marked for Chapel Hill/Carrboro).  Those exits are 22 miles apart along I-40, but the latter one is numbered with the I-85 sequence.  (Note that Exit 148 on I-85 is located near Mile Marker 149).

Taking that same idea over on the I-85 side, it is only about 17.5 miles between the two exits marked for Chapel Hill (Exit 148 and Exit 165).  That needs a big asterisk, because although Chapel Hill is not a control point shown on the BGS at the I-85/I-40 split, there are small green signs marked with secondary control destinations of "South Durham" and "Chapel Hill" for Exit 163 (I-40).

I-95 in Florida uses Orlando as a control city at Golden Glades for the Turnpike.  Then next, if your not counting supplemental signs as at Jupiter and Fort Pierce there are guides to inform motorists of the crossovers to the Turnpike that runs right next to it via SR 706 and SR 70, is SR 528 near Cocoa as main sign control cities.  Thus a complete distance of 193 miles between the two.

My question was about the furthest distances between two consecutive references to the same city/town along a given route (as I alluded to when mentioning the Kiowa, Colorado example).

And even after you clarified, they continue to miss the point.

If I'm missing something, let me know. I changed my thought process from "just farthest away exits period" (could have exits pointing towards that city between those spots) to "farthest exits without having another exit listed for that city in between".

How about I-80 with Detroit? From the I-90/I-94 exchange in Gary to I-280 in Toledo, the distance is approximately 206 miles.

EDIT: Originally, the post mentions I-75, but the exit signs there make no mention of Detroit, even though it does go there (instead, they read Toledo/Dayton). And I-90 shares I-80's alignment between these two endpoints.

Not sure how to work with this one. Just since the Turnpike doesn't have exits from I-95 and needs these other roads to get you there, it's almost as if they're designed to be pointed "towards Orlando". I hope that makes some sense.

I-70 Wichita:  115 miles (KS Exit 250A → KS Exit 366)

Does I-44 in Missouri count?  The eastern terminus turns into I-70 West.  If that counts as an exit, then it's 273 miles between I-49 and there (Kansas City).

Found another. I-15 and Reno between US95 in Las Vegas and I-80 in SLC. 419 miles.

And another: I-5 and San Francisco between I-505 and I-580. 117 miles.

There's also Montgomery on I-20 (127 miles from I-459 to I-285), and Birmingham on I-85 (150 miles from I-285 to I-65) but only if we're counting termini.

[webny99]

I-81, I-88, and I-90 form a triangle where this happens on all three routes.

I-81 mentions Albany at I-88 and I-90, 74 miles apart.
I-90 mentions Binghamton at I-88 and I-81, 124 miles apart.
I-88 mentions Syracuse at both termini, but only in the terminating direction, so I'm not sure if that counts. If it does, it's 117 miles.

Unless I missed something, {I-81>Albany, I-88>Syracuse, I-90>Binghamton} is still the only complete triangle we have so far (where > represents the route's location relative to the city).

Another (larger) triangle:
I-70>Louisville, I-64>Indianapolis, I-65>St Louis, which reminds me of something...

- I-65 Cincinnati at I-71 and I-74: 110 miles

Also the distance between two mentions of St Louis on I-65.

One with I-10 and San Diego: 384 miles

I measure it to be 279 miles:

AZ Exit 112 → CA Exit 58

[jmacswimmer]

Not sure if this should ultimately count or not, but I'll toss it out for discussion:

Durham, NC from I-95: 152 miles from I-40* to I-85

*Raleigh is the primary control city for I-40 west from I-95, but Durham appears once, and only once, at the ramp departure from I-95 south to I-40 west (the previous approach signage just lists Raleigh & Wilmington, with secondary control cities of Durham & Clinton added at the ramp departures).

Your second link's on CA 60, not I-10.

Aw snap, you're right.  Wrong highway, right exit number.  That makes the correct distance 297 miles to the other Exit 58.

[jdb1234]

Orlando is mentioned on I-75 first at the Florida Turnpike in Wildwood and in Mango, FL for I-4.  Total distance of 65 miles. 

Orlando is also mentioned on I-75 at FL 50.

Immokalee is mentioned on I-75 at FL 82 and again at FL 29 at a distance of 58 miles.  Exit 111 is signed for Immokalee Road, so it may not count.

Memphis and I-24. Google says 206 miles

Exit 74A/TN for I-840 West
Exit "44A" /IL (really Exit 0) for I-57 South

As I read the rules closer, I guess "intermediate"  interchanges count, so I need to cut this back to I-24 and I-65 in Downtown Nashville
Makes the distance a little shorter: 178 miles

Exit 46B/TN for I-65 South/To I-40 West
Exit "44A" /IL (really Exit 0) for I-57

[paulthemapguy]

Here's one that I thought was kind of silly, because it's either end of a whole Interstate highway.  I-17 mentions Los Angeles along I-10 west and I-40 west.  These are 139 miles apart (and yeah, it's not the exact southern end of I-17, but fairly close.)

[Techknow]

That is indeed silly to choose a control city that is 500+ miles away, I mean it's not like in happens in California right?

Well, US 101 stretching from LA to SF for 430 miles, should have two signs for LA right? They do but AFAIK the earliest sign you'll see is in San Jose.

Exit 388C at the I-280/I-680 Junction
Exit 43B (according to Wikipedia) at the CA-23 junction, and Exit 19A at I-405, and Exit 13A at CA-170

That's 369 miles for Los Angeles Sacramento

Edit: Oops missed the part of the post that says "These have to be actual exit signs for towns not located along the freeway" but my answer still works for Sacramento. It's a control city for both I-680 and I-405 despite being at least 80 miles away from US 101

[Scott5114]

I-40 in Oklahoma mentions Tulsa at Exit 170 (Kickapoo Turnpike) and not again until Exit 240B (US-75), where it is mentioned on supplemental signage. That's a distance of 70 miles. If you count only actual control city signage, Tulsa doesn't appear again until Exit 286 (OK-351 Muskogee Turnpike), a distance of 116 miles.

[froggie]

^ They look legit to me.  OP's own original example did not have "consecutive references".  There are several interchanges along I-70 between his example points.

Another one for the 100+ mile club:  I-90 references St. Paul at both I-35 and I-94...about 161 miles apart.  Minneapolis is not mentioned at I-94.

[roadman65]

I-57 has Indy at Effingham, IL for I-70 East, but does t appear again for 76 miles until I-74 East.

[roadman65]

Here is one on I-95 in SC.



You can see by the exit numbers how far apart they are.
