I noticed that Jefferson City, Missouri has no interstates nearby. Are there any others in the lower 48?

I think we've had a topic on this before, but...
Pierre, SD
Dover, DE
Annapolis, MD*
Carson City, NV+
*Has secret I-595, and considering how you count it, I-97.
+Will be connected by I-580 in the future.

Is connected now. The I-580 extension opened in 2012.
If you want to be real technical, Trenton NJ does not have any Interstates within the city limits, however, both Hamilton Township and Ewing Township which are considered suburbs of Trenton have Interstates that, in a way, "serve" Trenton. I-195 is probably the best example, because the western terminus of NJ 29 goes directly into Trenton itself.
And Juneau, Alaska, but that's because there are no roads at all leading out of Juneau due to being in the middle of a national park.

The OP carefully limited this to the "lower 48".
But Juneau isn't in the middle of a national park. Just the middle of nowhere.
How hard would it be for AK to apply for I-A5 from Juneau northwards to the new ferry terminal?

Assuming the Glacier Highway extension gets built at all -- the Federal courts seem to really have it in for that project -- the highway will still be mostly two-lane, with abundant at-grade intersections and not one grade-separated interchange. So it would not even come close to meeting conventional Interstate standards, which would be needed to get FHWA approval to sign it as an Interstate.
Besides, there is no longer any financial advantage to having the highway designated (even if unsigned) as an Interstate rather than just as part of AK 7. When Alaska's four paper Interstates were designated ca. 1980, Interstates got 90% Federal funding, higher than even the ridiculously high Federal share for Alaska's non-Interstate highways. That is no more.

Who talked about signing it? Plus Alaska interstates don't seem to need standards. :P

Oh, indeed, it would be a totally pointless designation!
To make this a bit more interesting then, I just realized that the only two states in the Lower 48 that are not served by an interstate ending in 0 or 5 are North Dakota and Vermont.
