Interstates Barely Part of a State's System

[OCGuy81]

EXCLUDING 3-digit interstates, what are some examples of interstates that have very low mileage in a particular state?  For this thread, I'll define low mileage as being under 30 miles.

A few that come to mind

I-15 in Arizona (29 miles)
I-70 in West Virginia (14 miles)
I-82 in Oregon (11 miles)
I-72 in Missouri (2 miles)

I know there are more, but these come to mind right away.

[Bickendan]

I-95 in DC

[1995hoo]

I-24 in Georgia

[walkingman]

I-55 in Tennessee
I-59 in both Georgia and Louisiana

[Zeffy]

I-76 in New Jersey (3 miles I think?)

[NE2]

I-97 in Maryland

Here's a crib sheet, updated through December 31, 2013:

I-44 in Texas

[mvak36]

I-41 in Illinois once it becomes an interstate

[Big John]

I-74 in Iowa

[OCGuy81]

I-97 in Maryland

Ha! That's a great one.

[Fred Defender]

I-41 in Illinois once it becomes an interstate

Am I the only one who finds this idea for renaming US41 (but only a select portion of it) I-41 preposterous? Are they planning to do the same thing with US31 in Indiana?

[OCGuy81]

Ah! Another I just thought of.

I-76 has about 2 1/2 miles in Nebraska.

Another dimension you could add is "Interstates which barely serve residents of states they run through" , and the two I-86 segments in Pennsylvania score on both counts.

[1995hoo]

I-66 in DC (not a state, but for this purpose it's close enough)

[OCGuy81]

Am I the only one who finds this idea for renaming US41 (but only a select portion of it) I-41 preposterous? Are they planning to do the same thing with US31 in Indiana?

Yeah, it's a bit unnecessary, IMO.  Kind of similar to I-39 being routed north, when US-51 was doing the job just fine. 

Not all freeways need a blue shield on em.

[Pete from Boston]

84 in Mass
93 in Vermont
95 in New Hampshire
95 in Delaware
68 in West Virginia (31.5 miles—I cheated)

[spooky]

I-81 in Maryland (and West Virginia)

[adventurernumber1]

Once/if I-49 gets built in Texas, it'll be about 5 miles.

[SSOWorld]

one could qualify I-95 in NY if it didn't serve enough cities

How about US41(I) instead?

[Grzrd]

Assuming that a letter suffix is not a "digit", I-69W (1.4 miles).

[pumpkineater2]

I-57 in Missouri

Not all freeways need a blue shield on em.

Yes they do!

[theline]

I-70 in West Virginia
I-59 in Louisiana
I-24 in Illinois and Kentucky

Huh? I-24 runs about 37 in IL and 94 miles in KY. The OP restricted the list to 30 miles in a state. I-70 in WV was already mentioned.

[Brandon]

I-74 in Iowa.
