How many interstates in the state you live in?

[thspfc]

7. Or 8. Or 9. Everybody's got their own opinion and they're all wrong.

Hmm? I-35, I-90, I-94, I-394, I-494, I-535, I-694. What are the others?

7: 35, 35W, and 35E are all the same
8: 35W and 35E count separately
9: 35, 35W, and 35E all count separately

Oh, duh. I would say that there's 7. But can we just get rid of the suffixes already?

[Roadwarriors79]

Arizona has 6 for now.

8, 10, 15, 17, 19, 40

I-11 is planned in the future.

[ilpt4u]

I'll take a shot of Indiana's interstates.

2di's: 64, 65, 69, 70, 74, 80, 90, 94

3di's: 164, 265, 275, 465, 469, 865

So, we have 8 mainline interstates and 5 (formerly 6) auxiliary interstates. That's a total of 13 interstates (formerly 14) in Indiana.

Did 164 and 865 actually exist at the same time?

After looking it up, I guess they co-existed for about 12 years, from 2002-2014

TX:
2, 10, 14  , 20, 27, 30, 35/E/W, 37, 40, 44, 45, 69/E/C/W, 110, 169, 345, 369, 410, 610, 635, 820
= 20 (if branches are combined) or 25 (if branches are considered separate/individual)

Dammit. I was so hoping no one had beaten me to this. I wanted to try from memory.

NaN (Not a number).

[hotdogPi]

NaN (Not a number).

0. I've told you before: since the EU calls them member states, you do live in a state.

[CNGL-Leudimin]

Ahem... per convention the States of the USA aren't counted as countries, but rather as national subdivisions. Therefore, I parse "state" as meaning national subdivision, and therefore my value for that is 'Aragon'. However, that value is not a State of the USA, and as such the number of Interstates is not an applicable field. Since it has to be an integer, it comes out as NaN instead of zero.

[Flint1979]

Michigan has 13 Interstate's.

[hotdogPi]

Since it has to be an integer, it comes out as NaN instead of zero.

NaN is a float, not an integer.

18 for Illinois if my count is correct. Soon to be 19 when I-490 is completed

Let us hash them out:

13 2DIs:
24
39
41 (maybe, barely)
55
57
64
70
72
74
80
88
90
94

11 3DIs:
155
172
180
190
255
270
280
290
294
355
474
490 Coming Soon

I believe 13 + 11 = 25, with the 26th coming soon

I probably wouldn't count 41, so 24 with 25 coming soon. Missed some of the 3DIs

[frankenroad]

I'll take this as an opportunity to try to name all the interstates in my state off my head. I've been on the ones bolded

2di:
70, 71, 74, 75, 76, 77 (concurrency with 76), 80, 90 (8)

3di:
270, 470, 670
271, 471
275, 475, 675
277
280 (for the sole reason to drive on a bridge), 480 (concurrency with 271), 680
490 (13)

Total: 21, been on 18

Edit: Removed 276, marked the ones I've been on

I've been on the same 18 out of 21.   Not too surprising as we're from the same corner of the state.

25....

I have been on all of them except the valley area 69* ones, 2,410, and 37.

I-49 should eventually go through northern Bowie County. Currently it ends at the Arkansas state line about 1/4 mile east of US71 and the service roads attach it to US71 which at that point is ALL in Texas.

[Bickendan]

Too many, California went way overboard with non-chargeable 3ds.

Let's see if I can remember off the top of my head:

I-5: I-105, I-205, (I-305), I-405, I-505 originally planned as I-5W, I-605, I-805.  FUTURE: 905. 
(future I-7 or whatever Route 99 is planned to be numbered as if that ever is upgraded to Interstate)
I-10: I-110, I-210, I-710
I-15: I-215 formerly known as I-15E
I-40
I-80: I-280, I-380, I-580 (formerly I-5W), I-680, I-780, I-880, I-980.  FORMER: I-480, original I-880 in Sacramento.

17 currently signed, 1 unsigned, and one 3di and one potential 2di that could be signed in the future.  4 former designations (I-5W, I-15E, I-480, original I-880).

Love how you (intentionally?) left off everybody's favorite CA interstate

LOL, it was not intentional!  Not at all!  And I've been on 238 many many many times, I just forgot. LOL

Demonic Hellspawn Interstates don't count...

Why Biz 80 isn't on the list?

Oregon:
5
82
84
105
205
405
Former:
80N
305
505

[TheStranger]

Why Biz 80 isn't on the list?

Technically it is (as unsigned I-305).  I intentionally omitted it since I wasn't listening Interstate business loops in general, though I can totally see a case for it being in there on its own.

7. Or 8. Or 9. Everybody's got their own opinion and they're all wrong.

8: 35W and 35E count separately
9: 35, 35W, and 35E all count separately

Oh, duh. I would say that there's 7. But can we just get rid of the suffixes already?

Never. With the suffixes and 494/694, we're the most uniquely numbered metro area around.

[bzakharin]

New Jersey has 76, 676, 78, 278, 287, 80, 280, 95, 195, and 295
