Your state’s border crossings ranked

[thspfc]

Rank your state's border crossings by importance.
My opinion for Wisconsin's top 10:

1. I-41/94 at the IL border
2. I-39/90 at the IL border
3. I-94/US-12 at the MN border
4. I-90 at the MN border
5. US-61/151 at the IA border
6. I-535/US-53 at the MN border
7. US-41 at the MI border
8. US-12 at the IL border
9. US-14/61 at the MN border
10. US-2 at the MI border (in Ironwood)

3.  I-10/US 95 at the Arizona State Line
4.  I-80 at the Nevada State Line
5.  I-40 at the Arizona State Line
6.  I-8 at the Arizona State Line
7.  US 50 at the Nevada State Line

No love for US 24 at OH on the Toledo/Fort Wayne route?
IN 10/IL 114 gets some traffic as an alternate to 80/94 for I-65 traffic, to jump over to I-57

[Roadgeekteen]

I'm going to try (just interstates):

I-84 MA/CT
I-95 MA/NH
I-93 MA/NH
I-95 MA/RI
I-90 MA/NY
I-91 MA/CT
I-195 MA/RI
I-295 MA/RI
I-395 MA/CT
I-91 MA/VT

[Max Rockatansky]

What about least important?  Here are some non-OHV examples for California:

-  Nipton Road on the Nevada State Line
-  Needles Highway on the Nevada State Line
-  K Street in the Arizona State Line
-  CA 299 on the Nevada State Line
-  Stateline Road on the Nevada State Line
-  Daylight Pass Road on the Nevada State Line
-  CA 266 on the Nevada State Line
-  Anges Wilson Road on the Arizona State Line
-  River Road (this is fun finding this one) on the Arizona State Line
-  CA 182 on the Nevada State Line
-  Red Rock Road on the Nevada State Line
-  Surprise Valley Road on the Nevada State Line
-  Barrel Springs Road on the Nevada State Line
-  County Road 1 on the Oregon State Line
-  All the roads leading to Goose Lake State Park in Oregon
-  Anything entering Oregon from CA 161
-  Hilt Road over the Oregon State Line
-  Grayback Road to the Oregon State Line

I guess now that I think about it US 6, CA 139 and US 97 would all be a step down from the original 15 in terms of importance I posted above.

Ohio (2019 AADT for each crossing in parenthesis)

Interstate crossings and 4 lane divided US routes included. Most others are below 10k AADT.

I-71/I-75 KY (153k)
I-471 KY (107k)
I-275 KY (81k)
I-75 MI (58k)
US 23 MI (48k)

US 52 WV (20,207)
US 30 IN (15,306)
US 24 IN (14,822)
US 50 WV (13k)

I'm actually surprised that I-80/90 at IN border ended up this low on the list, barely above I-77 WV as the second least used of the 14 interstate crossings. Thought it would be at least above the I-70 IN crossing.

Lots of trucks jump off at OH 15 and OH 49 and take US 20 into Indiana. But I don't think its enough to make a huge difference.

Also suspect US 24 takes some to the traffic from 80/90.

[ozarkman417]

I'm not going to make a list of border crossings for MO right now, but the Poplar Street Bridge (I-55, I-64/US 40, and formerly I-70) is at the top of the list for the state.

The Canadian crossings don't have accurate AADT numbers, but here are their rankings in importance:
1. Ambassador Bridge
2. Blue Water Bridge
3. Detroit-Windsor Tunnel
4. International Bridge (Sault Ste. Marie)

The Howe Bridge will jump to #1 when it opens.

Bonus:
Major non-trunkline crossings (over 5,000 AADT)
Lewis Rd (Monroe County -> OH): 13,632
Gumwood Rd (Cass County -> IN): 6,021

I-75 OH: 55,667
US-23 OH: 52,492

I-75 MI (58k)
US 23 MI (48k)

Interesting that our AADT numbers are off by a couple thousand for both routes. We both used 2019 data, and I'm assuming you also used the AADT point between the first/last exit in the state and the border.

Nevada:

1.  I-15 from California (47,000)
2.  US 50 from California  (27,400) (this includes a lot of pedestrian traffic too though)
3.  I-80 from California (36,500)
4.  I-15 from Arizona (24,000) (welcome, Utah)
5.  I-11/US 93 from Arizona (20,500)
6.  CA 28/NV 28 from California (12,900)
7.  AZ 95/NV 163 from Arizona (30,500) (this number is fluffy because of a lot of local traffic in Laughlin/Bullhead City)
8.  I-80 from Utah (5,850)
9.  US 93 from Idaho (4,150)
10.  US 95 from Oregon (Idaho) (2,750)

Edit: Being a Nevadan I tend to think of the "importance of border crossings" as "how much money visitors bring across the border at each crossing", so I ranked them intuitively that way.  I did go back and add representative 2019 AADT, and for the most part there's a correspondence.

Probably just a difference in which day OH and MI did their counts.

Correct me if I'm wrong, but I thought that AADT is counted with the total number of vehicles that crossed over the AADT sensor (or whatever it uses) in a year, then divide that number by 365, hence the word "average". If that's the case, theoretically, there shouldn't be that big of a difference between AADT counts of that same road in two states.

[US 89]

Going to use AADT numbers for this since I feel like all our interstate border crossings are about the same importance level. This is every state-maintained road that crosses the Utah state line:

I-15 at AZ line: 25000
I-80 at WY line: 16000
I-15 at ID line: 12000
I-84 at ID line: 9800
US 91 at ID line: 8500
I-70 at CO line: 7700
I-80 at NV line: 7600
US 89A at AZ line: 5200
US 89 at AZ line: 4800
SR 59 at AZ line: 4400
US 40 at CO line: 3200
US 491 at CO line: 3100
US 89 at ID line: 2800
SR 58/BL-80 at NV line: 2600
US 163 at AZ line: 2500
SR 162 at CO line: 2000
US 191 at AZ line: 1900
SR 43 at WY line (east): 1700
SR 200 at ID line: 1400
SR 23 at ID line: 1300
SR 16 at WY line: 1300
US 191 at WY line: 1200
SR 43 at WY line (west): 1200
SR 30 at WY line: 780
SR 56 at NV line: 590
US 6/50 at NV line: 420
SR 46 at CO line: 420
SR 30 at NV line: 400
SR 150 at WY line: 350
SR 42 at ID line: 260
SR 21 at NV line: 170
FA 1364 at CO line (not state maintained in Utah, but connects to SH 318): 70

I was initially surprised to see US 91 higher than two Interstate crossings, but it does make sense as Logan is the closest good-size city for Franklin County and a good chunk of southeast Idaho.

EDIT: bolding the ones I've crossed myself because why not.

[webny99]

I-75 OH: 55,667
US-23 OH: 52,492

I-75 MI (58k)
US 23 MI (48k)

If that's the case, theoretically, there shouldn't be that big of a difference between AADT counts of that same road in two states.

It depends if it's a short count or an ongoing count. This could vary by state. Here in New York, our data is mostly short counts (data is usually collected over a period of 3-5 weekdays, with equipment set up at the beginning of the count and taken down at the end) except for a few select locations which gather data year-round.

Obviously, there's going to be some variation with short counts, say if Ohio collected their data in April and Michigan collected theirs in June. But even if one state uses ongoing counts, you'd need both to do so for the numbers to be exact, and even then, the exact time frame could skew it a bit. I'm honestly surprised the numbers are as close as they are. I wouldn't have batted an eyelash at an even larger difference.

1. I-90 Washington

For Maryland:

3. I-68 at WV line

This seems a very high ranking for this crossing relative to other much more heavily traveled ones.

5. I-70 at PA line
30. US 522 at PA line

I-70 and US 522 are multiplexed at the state line. These are the same crossing.

[JoePCool14]

I'll try to do Illinois' just based on personal perception. Most of these are probably just crapshoots in no particular order.

1. I-80/I-94 with Indiana
2. I-94 with Wisconsin
3. I-270 with Missouri
4. I-39/I-90 with Wisconsin
5. I-70 with Indiana
6. I-90 with Indiana
7. I-74 with Indiana
8. I-80 with Iowa
9. US-20 with Iowa
10. I-64 with Kentucky

[JayhawkCO]

In the style of US89, here's Colorado by AADT:

1. I-25 Wyoming  (23,000)
2. I-25 New Mexico  (13,000)
3. I-70 Kansas  (11,000)
4. I-76 Nebraska  (9,900)
5. US550 New Mexico  (9,100)
6. I-70 Utah  (8,500)
7. US287 Wyoming  (4,200)
8. US491 New Mexico  (3,700)
9. US85 Wyoming  (3,500)
10. US287/385 Oklahoma  (3,100)
11. US491 Utah  (2,800)
12. CO140 New Mexico  (2,100)
13. US40 Utah  (2,000)
14. US160 New Mexico  (1,800)
15. US50/400 Kansas  (1,500)
16a. US285 New Mexico  (1,400)
16b. CO13 Wyoming  (1,400)
18a. US84 New Mexico  (1,200)
18b. US34 Nebraska  (1,200)
18c. CO113 Nebraska  (1,200)
21. CO127 Wyoming  (950)
22. CO41 Utah  (870)
23. CO159 New Mexico  (840)

25. CO71 Nebraska  (790)
26. US6 Nebraska  (710)
27. US138 Nebraska  (660)
28. CO23 Nebraska  (520)
29. CO11 Nebraska  (500)
30. CO17 New Mexico  (480)
31. CO125 Wyoming  (460)
32. US385 Nebraska  (430)
33. CO96 Kansas  (410)
34. US36 Kansas  (360)[/b]
35. CO172 New Mexico  (330)
36. CO90 Utah  (290)
37. US160 Kansas  (220)
38. CO116 Kansas  (120)
39. CO318 Utah  (110)
40. CO389 New Mexico  (100)

Bonus - Not a State Maintained Highway in Colorado, But State Maintained in Bordering State:
WYO430/Moffat CR10N (280)
WYO10/Larimer CR103 (233)
WYO214/Weld CR79 (199)
K-15/Baca CR-M (115)

The only ones I think I'd re-order would be having I-70 Kansas and I-76 Nebraska higher than I-25 New Mexico.  I think, by importance, the truck traffic on those routes brings it a little higher than the NM traffic which has some local Raton-Trinidad stuff going on.

I was a little bit surprised to see US550 New Mexico higher than US287 Wyoming as well as having CO140 the highest of the state routes.

Noob question: how do I find the AADT count on roads?
