Interstates with a full slate of capitals

[empirestate]

Since some folks were keen to get into this on my last topic, here it is:

Which Interstates serve the capitals of all states they pass through?

Multi-state Interstates only, please!  And as usual, give leeway with city limits, but not a ridiculous amount. So, I-40 serves Little Rock, but I-95 does not serve Dover, and so on.

Related inquiries:
Same question, but for US routes. And/or, instead of capitals, use states' largest cities. (These tend to produce more "winners".)

And, which Interstate (or US route) serves the most state capitals? It may be that the winner here does not have a full slate of its own, but serves more capitals than those routes that do.

I-5.

[adventurernumber1]

For capitals:

I-5.

Beat me to it 

Also, I-25 (Santa Fe, Denver, Cheyenne)

Can't think of any more at this exact moment.

EDIT: I also thought of the historic US 99 which went through Sacramento, Salem, & Olympia, same as I-5.

[The Nature Boy]

Interstate 96 is entirely in Michigan and serves Lansing.

That counts, right?

I-89 goes through Concord, New Hampshire and Montpelier, Vermont.

Aw crap, didn't read the OP thoroughly enough. I also can't believe I missed I-89.

I-5.

And, would I-5 be the only Interstate that serves all the capitals (Sacramento, Salem, Olympia) as well as all the largest cities (Los Angeles, Portland, Seattle), with bonus points since none of the capitals are also the largest cities?

(is that too far into triviality?)

Nope, I-25 is 3 for 3 as well: Santa Fe, Denver, Cheyenne.

I-69 was 2 for 2 before the extension: Lansing, Indianapolis.

Others (with 3 or more):

I-94: Bismark, St Paul, Madison
I-90: Madison, Albany, Boston
I-80: Sacramento, Salt Lake City, Cheyenne, Lincoln, Des Moines
I-70: Denver, Topeka, Indianapolis, Columbus
I-64: Frankfort, Charleston, Richmond
I-40: Oklahoma City, Little Rock, Nashville, Raleigh
I-20: Jackson, Atlanta, Columbia
I-10: Phoenix, Baton Rouge, Tallahassee
I-35: Austin, Oklahoma City, Des Moines, St Paul
I-65: Montgomery, Nashville, Indianapolis
I-95: Augusta, Boston, Providence, Trenton, Richmond, and Washington DC (for bonus points)

[NWI_Irish96]

Stupid Kentucky putting their capital in Frankfort instead of Louisville ruins it for I-65.

[Pete from Boston]

Stupid Kentucky putting their capital in Frankfort instead of Louisville ruins it for I-65.

And for 71.

[Thing 342]

Stupid Kentucky putting their capital in Frankfort instead of Louisville ruins it for I-65.

Stupid Missouri putting their capital in Jefferson City and Kansas putting theirs in Topeka kills it for I-35.

Though only I-5 gets the bonus points.

I-95: Augusta, Boston, Providence, Trenton, Richmond, and Washington DC (for bonus points)

Unfortunately 95 also goes through Connecticut, New York, Pennsylvania, Delaware, and Maryland and doesn't sniff their capitals so your list should end at Providence.

Never said my list was of consecutive ones.  Just interstates with 3 or more state capitals.

Actually, the I-95 list should end where it begins (at Augusta) as it doesn't catch even a whiff of Concord, NH either. 

[roadman65]

Lets move the Capital of NH to Portsmouth or Seabrook, the Capital of CT to Bridgeport, lets even make NYC the new Capital of New York and even Philly the new Harrisburg.  Then we make both DE's and MD's largest cities their respected state government centers, and I-95 will break the record.

Heck, lets make Fayetteville, Florence, Savanah,  and even Miami all state capitals and you give I-95 the full 100 yards and a total of  15!

[jp the roadgeek]

I-97 (now if they got smart, this would be I-83, and then we could say I-83 because it serves Harrisburg too). And that stupid little piece of I-93 in Vermont disqualifies it (Boston and Concord).  But I-87 counts.

[roadman65]

What about I-89?  It is a two stater and both states the highway serves its capitals (Montpelier and Concord).  I did not see the earlier post.
If I-87 counts then so should I-17.

Single-state Interstates do not count.

That was my point.  If we should include these intrastates like I-87 which cannot be serve multiple capitals then we should allow I-17 and of course the 3 Hawaii interstates.

Side note, but technically 2 of the 3 main Hawaiian Interstates are outside of Honolulu.  What the Census designates as Honolulu stops short of I-H3.

Not quite. http://en.wikipedia.org/wiki/Honolulu_County,_Hawaii

Honolulu County (officially known as the City and County of Honolulu, formerly Oahu County) is a consolidated city—county... Because of Hawaii's municipal structure, the United States Census Bureau divides Honolulu County into several census-designated places for statistical purposes.

There is some legitimacy to Honolulu not being the whole island (and US 301 not going through Jacksonville), but goat.

[empirestate]

Honolulu would count anyway because of metro-area leniency. But there's still the problem of intrastate-ness...

The Real I-69 passes through Lansing and Indianapolis.

[Henry]

I-85 starts in Montgomery and goes through Atlanta, but misses Columbia, Raleigh and Richmond. However, it goes through parts of the latter two cities' metropolitan areas, passing through Durham and ending in Petersburg.
