Major Metro areas with the highest exit numbers

[ilpt4u]

Another exercise to add on to this thread: Take on the highest exit number on each 2di in a metro area, add them together, and divide by the number of 2di. Which metro area will have the highest? This can bring down the averages of cities with interstates that has a western/southern termius, like I-45 in Houston or I-29 for Kansas City. Here are what I have already:

Chicago: [357 (I-57) + 347 (I-94) + 293 (I-55) + 160 (I-80) + 138 (I-88) + 107 (I-90)]/6 = 233.67

Where does I-94 have an Exit 347 in Illinois?

Pretty sure Exit 161 is the highest for both I-80 and I-94, along their multiplex entering IL from IN

The split freeways for Exit 160 is east of the ramp for Exit 161 since the Kingery/Borman sections of 80/94 were rebuilt

Where does I-94 have an Exit 347 in Illinois?

That's in Wisconsin, since I'm counting a whole metro area, and I-94 goes through 2 counties in Wisconsin that's part of the Chicago metro area

Here's the four major cities in the Texas Triangle:

For Houston:
[153 (I-69) + 98 (I-45) + 829 (I-10)]/3 = 360

For San Antonio:
[628 (I-10) + 142 (I-37) + 196 (I-35)]/3 = 322

For Austin:
(632 (I-10) + 277 (I-35)]/2 = 454.5

For Dallas:
[482 (I-35) + 85 (I-35W) + 512 (I-20) + 104 (I-30) + 284 (I-45)]/5 = 293.4

So Austin wins but only because I-10 has an exit in Caldwell County, which is considered part of the Austin Metropolitan Area. Otherwise Houston would win.

That feels like cheating, but I guess it technically counts.
Other than that, I'd be surprised if there's a better showing than Jacksonville: 362 (I-10) + 380 (I-95) / 2 = 371.

For the Twin Cities I'll do I-94 Exit 258, and I-35 Exit 152 which heading northbound is the last exit in the 651 area code.

Comes out to 205.

Since Canada has already come up, Toronto's exit numbers along 401 are in the 300s and the exits for Kingston (metro area over 100K) are in the low 600s.

It's too bad 417's exits don't continue the kilometer markers from 17, else we'd see exits in the 1500s or so through Ottawa.

[SkyPesos]

Speaking of km exits, imagine 4 digit exit numbers if I-10 in Houston uses km markers

1194: TX 99
1206: TX 6
1216: Beltway 8
1226: I-610
1235: I-45
1238: US 59
1245: I-610
1256: Beltway 8
1267: Spur 330
1285: TX 99

I-64 gets up to Exit 299 at I-264 / I-664 / US-58 in Chesapeake, VA.

In total, the entire Hampton Roads metropolitan area has close to 2 million people.

This can bring down the averages of cities with interstates that has a western/southern termius, like I-45 in Houston or I-29 for Kansas City. Here are what I have already:

St. Louis: [293 (I-44) + 249 (I-70) + 207 (I-55) + 40 (I-64)]/4 = 197.25
Chicago: [358 (I-57) + 347 (I-94) + 293 (I-55) + 262 (I-65) + 161 (I-80) + 138 (I-88) + 107 (I-90)]/7 = 238
Cincinnati: [192 (I-75) + 169 (I-74) + 77 (I-71)]/3 = 146
Cleveland: [247 (I-71) + 212 (I-90) + 163 (I-77) + 161 (I-80) + 11 (I-76)]/5 = 158.8

Indianapolis-

I-69: Exit 205 [future Exit 188] (Fishers)- ne of Indianapolis
I-65: Exit 141 (Lebanon)- nw of Indianapolis
US 31: Exit 136 (Westfield)- north of Indianapolis

I'll add on Indianapolis to the list in this thread so far:
[226 (I-69) + 146 (I-65) + 119 (I-74) + 104 (I-70)]/4 = 148.75
