States that are connected more to another state than their own

[roadman65]

The discussion about the least amount of lanes between two states got me inspired to come up with this one here.

In New York you have State Island connected to New Jersey via twelve lanes on three crossings, while its connected to the rest of the state via 12 lanes on one crossing into Brooklyn and with the Staten Island Ferry not taking autos anymore it is only the Verazzano Bridge that has the only way to take your car intrastate to the rest of the state's land areas. 

Now you have the same amount of lanes from one area going from one section of a state to another as to its neighbor or even outside of its state.  Yet, in Virginia you have its Eastern Shore only connected to its mother land via four lanes on bridge, but narrows to two inside two of its tunnel going across the large water body, but more going to neighboring state Maryland as you have four of US 13 and many local two lane roads.  Thus having Eastern Shore of Virginia being more road accessible to Maryland than Virginia.

Then if you want to count Michigan's two peninsulas as two separate regions, you have only the four lanes of I-75 on the Mighty Mac connecting the two regions of Michigan while both Lower and Upper Peninsula have endless amounts of crossings to neighboring states and even Canada.  All except the UP and Canada with only two lanes of I-75 being two less than the Mackinac Bridge.

Any other areas of a state have more roads leading to another state than its own whether small or even a big concentrated area?

[Mapmikey]

Washington DC on Columbia Island has 17 lanes connecting to Virginia and zero lanes connecting to any other part of DC...

The UP of Michigan is similar to the eastern Shore Virginia example.

Knotts Island NC has 6 lanes connecting to Virginia and zero to any other part of NC.

Point Roberts, WA is only accessible from Canada.

[hotdogPi]

Directly south of Fall River MA is a section of Rhode Island that is only accessible from Rhode Island on RI 24, but has many Massachusetts crossings.

[CNGL-Leudimin]

Any point that is contiguous to its territory but it can only be accesed from another territory qualifies. Point Roberts, the Northwest Angle, Os de Civis (Spain), that Austrian valley I forgot its name...

Estcourt Station, ME is only accessible from Canada, and is the only point in Maine that has a 418 area code.  And Campobello Island, NB, is only accessible from Lubec, ME

[hbelkins]

Kentucky Bend, in the far western part of the state, is cut off from the rest of Kentucky by the Big Muddy, and is only accessible from Tennessee.

On the far other end of the state, Vulcan, WV, is accessible only via bridge from Pike County, Ky.

There is also another small section of Pike County, Ky., that can only be accessed by going through a part of Virginia. And a few spots along the Virginia secondary route that leads to that area are "islands" surrounded by the other state.

Same can be said of a few spots along WV/VA 102 between Bluefield and Pocahontas, where the road crosses the state line several times.

Hyde, AK, which is so disconnected from everywhere else that it is the only place one can legally enter the US without first reporting to customs (you can't leave without reporting to Canada though; I presume they have a station solely to prevent people from driving away immediately after getting "Hyderized").

Estcourt Station, ME is only accessible from Canada, and is the only point in Maine that has a 418 area code.

Technically there are logging roads that connect it.

Hyde, AK, which is so disconnected from everywhere else that it is the only place one can legally enter the US without first reporting to customs (you can't leave without reporting to Canada though; I presume they have a station solely to prevent people from driving away immediately after getting "Hyderized").

No, until the customs station was opened in 1996, the RCMP kept an eye on the border for DUI violations. (So warned the town paramedic when I visited in 1994. She strongly urged me to walk around town for several hours while my Hyderization wore off.) More likely the station was to catch people smuggling low-tax American tobacco and alcohol from Hyder into Canada.

To expand the point about Alaska, all of southeastern Alaska has three roads (all two-lane and paved) into British Columbia (the roads out of Hyder, Haines, and Skagway), but the only motor vehicle connection to the rest of Alaska not going through B.C. and Yukon is the "cross-gulf" auto ferry line between Prince William Sound and Juneau.

An obvious answer is da UP, which is more easily accessible to Wisconsin than the rest of Michigan.

[Bitmapped]

There are a couple parts of Monongalia County, West Virginia that are only accessible from Pennsylvania.

The entire Eastern Panhandle of West Virginia is only connected to the rest of the state by 2 lanes (WV 9).

[hbelkins]

Are there no county routes that connect Hampshire and Morgan counties?

[corco]

Alta, Wyoming is only accessible from Idaho.

The only paved connections to the Arizona Strip are only accessible by Nevada and Utah.

Idaho north of the Salmon River ( which is about a third of the state) has only two connections, one paved, to the rest of the state but dozens of connections to Washington.

[froggie]

Are there no county routes that connect Hampshire and Morgan counties?

There's one near the river due south of Paw Paw.  But I don't think Brian was referring to county lines, but instead to Cacapon Mountain...the mountain that parallels US 522 about a mile to the west.  There is only one road crossing of that mountain in West Virginia connecting to the eastern panhandle:  WV 9.  To the north is the Potomac.  The next road crossing to the south isn't until WV/VA 127.

[1995hoo]

Washington DC on Columbia Island has 17 lanes connecting to Virginia and zero lanes connecting to any other part of DC...

....

Do you not count Arlington Memorial Bridge as having lanes that connect to another part of DC, perhaps because of National Park Service jurisdiction versus DC government jurisdiction? It still qualifies for the OP's point because there are more lanes connecting to Virginia than there are across the bridge, of course. I'm just curious about the reasoning behind "zero lanes connecting to any other part of DC."


Regarding the original topic, there is a small area of Quebec accessible by land only from New York State. I cannot tell from the Google Maps imagery how many lanes there are because there is no Street View, but it appears to be two two-lane roads for a total of four lanes. The area is part of an Indian reservation, which probably explains why I don't see any signs of Customs facilities in either country for that little area:

There are countless examples of river-course boundary changes that strand territory across said river, inaccessible completely from its own state.  Too many to mention, really. 

[TheCatalyst31]

Kaskaskia, IL, is probably one of the more famous cases of a river-course change cutting off part of a state. It used to be the capital of Illinois, but now it's practically a ghost town and only accessible via Missouri.

[agentsteel53]

there are precisely two roads from Ontario into western Canada.

plenty of roads from the US into Western Canada.

[Alps]

There are zero roads between any of the Hawaiian islands. They are therefore equally connected to Antarctica.

No, really, what?

[Brandon]

There are zero roads between any of the Hawaiian islands. They are therefore equally connected to Antarctica.

No, really, what?

And there are no roads between any of the counties in Hawai'i either.  Even the one connected by land.

[Road Hog]

There are fingers of land created by Bull Shoals Lake in extreme northern Arkansas that are accessible only through Missouri. I believe those land areas have Missouri addresses and phone numbers and may even send their kids to Missouri schools.

Yes, I was referring to Cacapon Mountain.

[mcdonaat]

Louisiana east of the river connects to Mississippi more than the west side of the river. 39 lanes of river crossings, versus too-many-to-count state highways and county/parish roads crossing the border.

[Landshark]

Idaho north of the Salmon River ( which is about a third of the state) has only two connections, one paved, to the rest of the state but dozens of connections to Washington.

The panhandle of Idaho is better connected to WA, MT, and BC Canada than it is the rest of Idaho.
