Title: How many states are directly connected to yours via an interstate or US highway?
Post by: KCRoadFan on March 03, 2021, 09:59:56 PM
Here's an interesting game I thought up recently.

Think of the interstates and US highways that go through your state. Using those highways, how many states are directly connected to yours - that is, how many states are served by the interstates and US routes that go through your state? (In other words: if you were to get on an interstate or US highway somewhere in your state and drive in either direction, how many states could you reach by "following the number" without subsequently turning off the route?) What are some of the most- and least-connected states in that regard?

Obviously, Hawaii has no such connections; Alaska only connects to three states, if you count the Alaska Highway as being an extension of US 97 via BC 97.

Anyway, to start things off, here's a list of states that my state of Missouri is directly connected to via interstates or US highways. (In the following list, the first mention of a state will appear in boldface.)

I-29: IA, SD, ND
I-35: TX, OK, KS, IA, MN
I-44: TX, OK
I-55: LA, MS, TN, AR, IL
I-64: IL, IN, KY, WV, VA
I-70: UT, CO, KS, IL, IN, OH, WV, PA, MD
I-155: TN
I-255: IL
I-270: IL
I-435: KS
I-635: KS
I-670: KS
US 24: CO, KS, IL, IN, OH, MI
US 36: CO, KS, IL, IN, OH
US 40: UT, CO, KS, IL, IN, OH, WV, PA, MD, DE, NJ
US 50: CA, NV, UT, CO, KS, IL, IN, OH, WV, VA, DC, MD
US 54: TX, NM, OK, KS, IL
US 56: NM, OK, KS
US 59: TX, OK, KS, IA, MN
US 60: AZ, NM, TX, OK, IL, KY, WV, VA
US 61: LA, MS, TN, AR, IA, MN
US 62: TX, NM, OK, AR, IL, KY, OH, PA, NY
US 63: LA, AR, IA, MN, WI
US 65: LA, AR, IA, MN
US 67: TX, AR, IL, IA
US 69: TX, OK, KS, IA, MN
US 71: LA, AR, IA, MN
US 136: NE, IA, IL, IN
US 159: KS, NE
US 160: AZ, NM, CO, KS
US 169: OK, KS, IA, MN
US 275: IA, NE
US 400: CO, KS
US 412: NM, OK, TN

Based on the above list, we can see that Missouri is directly connected to 31 states (as well as DC) by interstate or US highways! How do other states measure up?

Think there were maps a couple of months ago of something similar to this, but with number of counties instead of states. Illinois came out on top of the county maps.

But I'll play along with Ohio (duplicates not listed):

I-90: WA, ID, MT, WY, SD, MN, WI, IL, IN, PA, NY, MA (12)
I-80: CA, NV, UT, NE, IA, NJ (18)
I-77: SC, NC, VA, WV (22)
I-75: FL, GA, TN, KY, MI (27)
I-70: CO, KS, MO, MD (31)
US 6: CT, RI (33)
US 20: OR (34)
US 40: DE (35)
US 50: DC (36)
US 52: ND (37)
US 62: TX, NM, OK, AR (41, 40 without DC)

States missing (excluding AK and HI): AL, AZ, LA, ME, MS, NH, VT


EDIT: Decided to try Illinois too to see if it's the winner of the states in addition to the counties:

I-94: MT, ND, MN, WI, IN, MI (6)
I-90: WA, ID, WY, SD, OH, PA, NY, MA (14)
I-80: CA, NV, UT, NE, IA, NJ (20)
I-70: CO, KS, MO, WV, MD (25)
I-64: KY, VA (27)
I-55: LA, MS, TN, AR (31)
I-24: GA (32)
US 6: CT, RI (34)
US 20: OR (35)
US 40: DE (36)
US 41: FL (37)
US 45: AL (38)
US 50: DC (39)
US 52: NC, SC (41)
US 60: AZ, NM, TX, OK (45, 44 without DC)

States missing (excluding AK and HI): ME, NH, VT

Indiana is connected to 37 states and DC via interstates and US highways.

**Interstate 69 (if fully completed) would get another 4 new states: MS, AR, LA, TX, for a total of 41 states and DC.**

For Virginia interstates....

I-64 - WV, KY, IN, IL, MO
I-77 - SC, NC, WV, OH
I-81 - TN, WV, MD, PA, NY
I-85 - NC, SC, GA, AL
I-95 - FL, GA, SC, NC, MD, DE, PA, NJ, NY, CT, RI, MA, NE, ME
I-495 - MD

22 states via the interstate highway system. I-395 and I-66 also connect to DC, along with I-95.

In the future, we may see I-73 connect to NC and SC, I-785 connect to NC, and I-87 connect to NC.

I-76: NJ (1)
I-78: NY (1)
I-79: No new states added
I-80: CA, NV, WY, NE, IA (5)
I-81: TN, VA (2)
I-83: No new states added
I-84: CT, MA (2)
I-86: No new states added
I-90: WA, ID, MT, SD, MN, WI (6)
I-95: FL, GA, SC, NC, DC, DE, RI, NH, ME (8 plus DC)
I-99: No new states added
US 1: No new states added

US 13: No new states added
US 15: No new states added

US 20: OR (1)
US 22: No new states added
US 30: No new states added
US 40: No new states added
US 62: TX, NM, OK, AR, KY (5)

None of PA's 3-digit Interstate or US Routes add to this list.

There are no direct routes from PA to AZ, MI, ND, or VT. I-80 and I-90 just miss adding MI to the list by less than one mile, as does US 11 with VT! Closest state not connected is VT.

Total: 43+DC

While I think both segments should count, I put down numbers for just western US 2 and all of US 2 for Montana. Let others decide what is the "right" number.

I-70: CO, KS, MO, IL, IN, OH, WV, PA, MD
I-80: CA, NV, WY, NE, IA, IL, IN, OH, PA, NJ
I-84: OR, ID (eastern doesn't count, and it doesn't matter anyway since US 6 covers them)

US 191: AZ, WY, MT
US 491: NM, CO

Closest not connected is South Dakota, which is somehow closer than both Washington and Oklahoma.

It seems like we're not counting I-69 (or other disconnected routes with the same number) except the original section between Indianapolis and Port Huron because it's a disjointed mess that probably won't get finished within the next 30 years. So the only extra state you have is Indiana as the other I-69 states are covered by other routes from Mississippi.

Post by: sprjus4 on March 04, 2021, 12:51:19 AM
The segment of I-69 from the Tennessee / Kentucky state line to Indianapolis will soon be connected to the original, so it would make sense to at least include that.

South of there is a different story.

Since this exercise doesn't work for my current location, I'll do this for my previous homes in KS and SC. I excluded highways that didn't add any new states to prevent these lists from being ridiculously long.

US-159: NE, MO
US-160: AZ, NM, CO, MO
US-81: TX, OK, NE, SD, ND
Excluded 14 redundant US highways and didn't even get to the interstates. 25 states + DC

For Virginia interstates....

I-64 - WV, KY, IN, IL, MO
I-77 - SC, NC, WV, OH
I-81 - TN, WV, MD, PA, NY
I-85 - NC, SC, GA, AL
I-95 - FL, GA, SC, NC, MD, DE, PA, NJ, NY, CT, RI, MA, NE, ME
I-495 - MD

22 states via the interstate highway system. I-395 and I-66 also connect to DC, along with I-95.

In the future, we may see I-73 connect to NC and SC, I-785 connect to NC, and I-87 connect to NC.


Finishing Virginia (new states only):
US 11 - LA, MS
US 23 - MI
US 50 - CA, NV, UT, CO, KS
US 52 - ND, MN, IA

33 in total

US 50: NV, UT, CO, KS, MO, IL, IN, OH, WV, VA, DC, MD

Total: 32 states, including DC

I'm not counting decommissioned routes in the leaderboard, but if we included them, US 40 would add DE, US 60 would add KY and US 80 would add GA, which would bring the total up to 35.

Found an older thread that may compliment this thread pretty well. It's about the closest states not directly connected by a single numbered highway.

This is very impressive, but also not surprising, considering the number of key routes that have to bend down here to get around the Great Lakes.

The reason I chose Illinois for the county thread was because I knew it had the state record (although it might have tied; I can't remember).

The thing about Illinois is that of the top three cities in the US outside Illinois (New York City, Los Angeles, and Houston), Illinois routes hit none of them.

It used to serve one of them with two routes in the past (LA with US 6 and US 66), but not anymore

If we're counting the top 3 metro areas outside Illinois (NYC, LA, Dallas), Illinois gets 2 of the 3 (3/3 with US 66), with I-80 to NYC, US 67 to Dallas.

One only needs to bring back US 66 and extend I-80 a few miles and you've got the two biggest taken care of.

If you're nitpicky that I-95's couple hundred feet in DC doesn't count, US 1 goes through all of I-95's states except Delaware, so that total will be 25.

Closest is Colorado actually. I was surprised that there's no routes from Colorado to the Pacific NW states with how close they are geographically. From the NW corner of Colorado to SE corner of Idaho, it's a straight line distance of 125 miles.

I don't count IL for I-41. And the eastern US 2 is separate route. So it's really 21.

I've counted this three times now and keep getting 23.  (The I-41/IL thing doesn't matter since many other routes connect the two.)

Not sure how to count things like US route E/W splits or routes that have a discontinuous portion through Yellowstone, but here's the behemoth that is NY, presuming I didn't miss anything and counted right.

New York:
-I-78: PA, NJ
-I-81: TN, VA, WV, MD, PA
-I-84: PA, CT, MA
-I-86: PA
-I-90: WA, ID, MT, WY, SD, MN, WI, IL, IN, OH, PA, MA

-I-99: PA**
-I-278: NJ
-I-287: NJ
-I-684: CT*
-US 1: FL, GA, SC, NC, VA, DC, MD, PA, NJ, CT, RI, MA, NH, ME
-US 2: VT, NH, ME
-US 4: VT, NH
-US 6: CA, NV, UT, CO, NE, IA, IL, IN, OH, PA, CT, RI, MA
-US 9: DE, NJ
-US 9W: NJ
-US 11: (LA, MS, AL, GA, TN), VA, WV, MD, PA
-US 15: SC, NC, VA, MD, PA
-US 20: (OR, ID, MT), WY, NE, IA, IL, IN, OH, PA, MA
-US 44: CT, RI, MA
-US 62: TX, NM, OK, AR, MO, IL, KY, OH, PA
-US 202: DE, PA, NJ, CT, MA, NH, ME
-US 209: PA
-US 219: VA, WV, MD, PA

Total:
-44 if including all
-43 if including US 11 south of the split in TN/VA but not US 20 west of Yellowstone
-41 if including US 20 west of Yellowstone but not US 11 south of the split in TN/VA
-40 if including neither US 11 south of the split in TN/VA nor US 20 West of Yellowstone

*Passes though, no exit
**Ends at border, extension planned

For Virginia interstates....

I-64 - WV, KY, IN, IL, MO
I-77 - SC, NC, WV, OH
I-81 - TN, WV, MD, PA, NY
I-85 - NC, SC, GA, AL
I-95 - FL, GA, SC, NC, MD, DE, PA, NJ, NY, CT, RI, MA, NE, ME
I-495 - MD

22 states via the interstate highway system. I-395 and I-66 also connect to DC, along with I-95.

In the future, we may see I-73 connect to NC and SC, I-785 connect to NC, and I-87 connect to NC.


Finishing Virginia (new states only):
US 11 - LA, MS
US 23 - MI
US 50 - CA, NV, UT, CO, KS
US 52 - ND, MN, IA

33 in total

Dang it...

Forgot US 60 - AZ, NM, TX, OK

So 4 more for Virginia

In numerical order, adding only states not previously listed.

I-24: Illinois, Tennessee, Georgia.
I-64: Missouri, Indiana, West Virginia, Virginia
I-65: Alabama
I-69: Not counted since it's a discontinuous route at the moment.

US 340:  WV, VA
US 522:  PA, WV, VA

Unless I've miscounted (which is a definite possibility) I get 28 states plus DC.

Methinks Maryland needs to ranked a bit higher - pretty good for such a small state if I do say so myself.

The rest of Delaware's Interstate and US Routes do not add any new states to the list. US 40 formerly added NV and CA. US 50 misses Delaware by less than a mile and would add CA, NV, and KY. Closest not connected is VT.

US 6 helps Colorado get a lot of the states in the Northeast, along with US 40 and US 50. Missouri have the latter two, but doesn't have US 6. Texas only have US 62 to the northeast, which doesn't go far enough to hit any of the smaller states. The short section of US 84 in Colorado also helps it get most of the states in the Southeast.

Unless I've miscounted (which is a definite possibility) I get 28 states plus DC.

Methinks Maryland needs to ranked a bit higher - pretty good for such a small state if I do say so myself.

Kentucky's interstates touch surprisingly few other states.

In numerical order, adding only states not previously listed.

I-24: Illinois, Tennessee, Georgia.
I-64: Missouri, Indiana, West Virginia, Virginia
I-65: Alabama
I-69: Not counted since it's a discontinuous route at the moment.
I-71: Ohio
I-75: Michigan, Florida

That's only 11 states.
I'll add in the US routes for KY too. Lmk if I'm missing any state.
US 25: NC, SC (13)
US 51: LA, MS, WI (16)
US 52: ND, MN, IA (19)
US 60: AZ, NM, TX, OK (23)
US 62: AR, PA, NY (26)

Surprisingly, no same numbered route between Kentucky and Kansas, considering they're only one state (Missouri) apart.

Then I saw US 52. I didn't count it because it doesn't officially enter Kentucky, at least not according to KYTC. The road is owned and maintained by WVDOT.

Umm ... I already did Maryland yesterday.  The count is actually 28+DC.  Looks like you counted Georgia twice.

My bad.  Went by the scoreboard and missed it.

But you can drive from a point in Kentucky, get to US52 in Kentucky by not entering another state (as in arriving from KY292) and drive to the other states.  I feel my point stands.

I'm going to try something with Vermont; how many states can Vermont connect to if you're allowed to change to another I/US route once outside the state. All other states would most likely be at least 47/48 with this, but not Vermont.

The states VT connects directly with a single route: CT, MA, ME, NH, NY (5)
I-91 -> I-95: FL, GA, SC, NC, VA, DC, MD, DE, PA, NJ, RI (16)
I-91 -> I-90: WA, ID, MT, WY, SD, MN, WI, IL, IN, OH (26)
I-91 -> US 6: CA, NV, UT, CO, NE, IA (32)
I-91 -> US 20: OR (33)
US 2 -> US 11: LA, MS, AL, TN, WV (38)

Since we're going international, here's "How many provinces are directly connected to yours via a TCH highway?":
1 - New Brunswick, Nova Scotia (9)
3 - British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Québec, Newfoundland and Labrador (8)
10 - Prince Edward Island (2)
11 - Yukon, Northwest Territories, Nunavut (0)

The reason for the differences is that each branch is counted separately, so the branch between NB/PEI/NS counts as a separate route as the mainline (as do the others, but they're irrelevant because the mainline goes to every province except PEI).  If we were to add the Alaska Highway, the Yukon would be below PEI with 1, and British Columbia would join New Brunswick and Nova Scotia for 9.

Going off the top of my head, I think if you're allowed to change routes once after leaving the state, Kentucky gets 46 of the lower 48, excepting only OR and VT. It helps that the north-south routes through Kentucky (I-75 and I-65) intersect the transcontinental routes like 10, 40, 80, and 90, and another long route in 94. Also, I-64 intersects I-81 and I-95, which gets much of the northeast and mid-Atlantic.

Oregon is possible as you can change to US 20 or US 30 from some of Kentucky's routes in another state. So that leaves Vermont as the only one out.

Yes, but I was counting only interstate-to-interstate connections. And I-75 does connect to US 2, so wouldn't that get Vermont?  :bigass:

My guess is that the Ohio Turnpike will intersect I-75 at Bowling Green instead of at its current location of Perrysburg, and will closely parallel US 6 from the IN border to about Fremont, where it will resume its current routing. I think US 20 will still have a short segment through "Toledo, Michigan", which by itself, would add in a lot of states for Michigan for this thread.

I'll try this with Chinese Provinces. Without HK, Macau and Taiwan, there's 31 total subdivisions.

Shanghai:
G2: Jiangsu, Shandong, Hebei, Tianjin, Beijing (5)
G15*: Guangdong, Fujian, Zhejiang, Liaoning (9)
G40: Shaanxi, Henan, Anhui (12)
G42: Sichuan, Chongqing, Hubei (15)
G50: N/A
G60: Yunnan, Guizhou, Hunan, Jiangxi (19)
G312: Xinjiang, Gansu, Ningxia (22)
G318: Tibet (23/30)

Missing: Heilongjiang, Jilin, Inner Mongolia, Shanxi, Qinghai, Guangxi, Hainan
*G15 is disconnected between Shandong and Liaoning, with an undersea tunnel planned to connect them. Also, it's planned to go into Hainan, but no section of G15 currently exists in Hainan. I counted the Liaoning portion, but not Hainan.

Fujian (freeways only):
G3: Zhejiang, Anhui, Jiangsu, Shandong, Hebei, Tianjin, Beijing (7)
G15: Guangdong, Shanghai, Liaoning (10)
G25: Jilin (11)
G70: Ningxia, Gansu, Shaanxi, Hubei, Jiangxi (16)
G72: Guangxi, Hunan (18)
G76: Sichuan, Guizhou (20/30)

I can't find a list of the national highways that go through Fujian; all I know about those is that G319 enters Chongqing and G324 enters Yunnan for new additions to the list.

Looking through my old threads, and I decided I'm bumping this one to clarify that Missouri is directly connected to only 31 states (plus DC), and not 32 as I had put originally. Looking back at this post, I realized that when I did my count, I had counted Tennessee twice, which I didn't notice at the time I posted it.

Anyway, I already updated my original post accordingly. And as for whoever posted the leaderboard - you'll need to update the number for Missouri, from 33 to 32 (including DC).
