Hartford does not have one within the city limits. The western terminus of I-291 is about a mile north of the city line, and I-384 ends 5 miles east.  Boston also doesn’t have a 3di within 25 miles (I-495).

Discussed in the other thread, metro areas make far more sense than city limits. Does anyone really feel like I-495 isn't "Boston's" loop?

495 serves Needham, not Boston!   :spin:

Shoot, the Capital Beltway wouldn't "serve" Washington other than the 400' or whatever it is on the bridge if we looked at it like that.

I suggest that the Augusta situation is a little different from the others you've mentioned and that's why I was trying to frame my post carefully.

Sure. ME I-295 doesn't have quite the same intent as the I-495s discussed, but it's still within a few miles of the city and has a direct exit to Gardiner which is a "suburb" of Augusta.

Sacramento is an interesting example because for 14 years, it did have a signed 3di in its city limits (the former I-880 that got taken over by I-80 mainline when Business 80 and the hidden I-305 were created).

Under my humble definition - < 10 miles non-freeway connection or < 20 miles freeway connection - 295 does serve Augusta.

I can see the argument both ways for Augusta, but I see I-295 as having more of a 2di-type function there. It's more comparable to the I-80/I-76 split in western NE than it is to your average spur 3di.

And while it does have an exit for Gardiner, most traffic from Augusta is going to use US 201 to get to Gardiner.

I mean, I-580 is more "2di like" for Carson City, but it's still a 3di no matter what.

Interesting how 40% of state capitals aren’t served by a 3-di

Well, some states are very small, and some quite large states have chosen to place their capital in something other than the largest city, or in some cases in places that can hardly even be called a city.
As a South Dakotan, I am offended! However, as someone from Spearfish, mocking Pierre is acceptable and quite good. What state capital has their (or a, depending on the size of capital) high school mascot as the Governors?

Ah, lest we forget, Missouri's and Delaware's capitals don't even have a 2di.

There was a proposed I-570 for Jefferson City. No idea if that is still on the books.

According to interstate-guide.com, nobody but the Jefferson City chamber of commerce ever advocated I-570.

I see news articles from 2020 stating that the chamber of commerce keeps saying an Interstate spur is needed but, as far as I can tell, they're really just talking to themselves.

LOL...

"No schedule for constructing Interstate 570 was ever planned, and the project was unfunded. The proposal never gained traction, with only the chamber of commerce openly advocating it. The Missouri Department of Transportation (MoDOT) did not propose this route, nor has the American Association of State Highway and Transportation Officials (AASHTO) approved it. As of 2006, no known studies were made to upgrade this corridor to Interstate standards."

Austin is the second most populous state capital in the country and doesn't have a 3di.

Do they need one?  I mean, I know they need more freeway capacity, but would turning an existing freeway into a 3di do anything special?

Correction:  It's actually in the Missouri Chamber of Commerce report from 2020, titled Transportation 2030: Making Missouri a Leading Logistics Hub.  However, accessing that report requires a request for download.

It was, however, quoted in the News Tribune:

Quote from: News Tribune – Jefferson City needs an interstate highway spur, report says –22-OCT-2020
The Missouri Chamber of Commerce's "Transportation 2030: Making Missouri a Leading Logistics Hub" report, released this week, includes a recommendation that "Several smaller metros noted inadequate existing (highway) interchanges, the need for new interchanges to encourage economic development, and the benefit of developing a new interstate spur to areas like Jefferson City."

My point was population has nothing to do with it.  The most populous state capital is also the 6th largest city in the country and no 3di.

You're aware that DC has three other 3-digit Interstate routes besides that 400ft of the Capital Beltway, right?

Here's a question that got mentioned upthread but not definitively answered by the OP:  are we referring to the capital city's metropolitan area?  Or are we just talking within the city limits?  Because this dictates whether at least one other state is included or not.

Phoenix did once have a signed I-510 that got partly absorbed into an I-10 reroute and otherwise renumbered as SR 51.
