How many US state capitals don't have direct Interstate connections? The only one I can think of is Jefferson City, Missouri, but I'm sure there are others.
Jefferson City, MO is not far off from I-70, much like how Pierre, SD is not far off from I-90.
Fairly certain we've had this thread before. I believe the answer is now 4:
-Pierre, SD
-Jefferson City, MO
-Dover, DE
-Juneau, AK
Carson City, NV was also on that list until a few years ago, when I-580 was extended down from its previous endpoint south of Reno.
Yeah, this has been covered multiple times going back to m.t.r, I am sure.
My home state's capital is one of them.
Although four don't have interstate connections, three of them are connected to an interstate by a four-lane divided highway (US-54 among others to Jeff City, US-83 to Pierre, DE-1 and US-13 to Dover). Only one without four lane road access (or any access) is Juneau.
