State Capitals Without Interstate Highways

[swbrotha100]

So now that I-580 in Nevada is officially signed along US 395 in Carson City, how likely is it for the remaining capitals currently without interstates to gain a 2di or 3di in the future? I don't see it happening in Alaska (Juneau). Maybe Delaware (Dover) and Missouri (Jefferson City) someday. Very unlikely in South Dakota (Pierre).

Of the two you say "someday" for, I'd say Dover is far more likely, if only because of the sheer number of times DE 1 gets upgraded on the fictional highway threads.

We know.

I would imagine that Dover gets one the soonest. Maybe an I-195 south from Wilmington? Maybe an I-170 from I-70 along US 54 (which appears to be freeway for some miles) to Jefferson City.

As for Pierre, I doubt there is enough traffic from I-90 toward Pierre, but there could be a possibility along US 83.

Juneau? Not gonna happen.

DE 1 I believe would have been considered for interstate status if it hadn't been built as a toll road.

Doesn't mean an I-number can't be slapped on it.

Agreed.  When Alaska became a state, it proposed Interstate designation for an auto ferry route in southeast Alaska, that would've served Juneau.  That idea got nowhere.  (Other Interstate routes in Alaska were rejected as well, though Congress in the 1980s required designation of Alaska's current network of "paper Interstates".)  See http://www.alaskaroads.com/1960-Alaska+Hawaii-Interstates-report.pdf (in particular, PDF document pages 26 and 33).

Like Hawaii's interstates have an H prefix, I imagine any interstate in Alaska will probably have an A prefix, which will interest Autobahn enthusiasts no doubt.

I'm thinking "not likely" in Jefferson City, unless US 63 suddenly becomes an I-x70.

In Alaska, only if the capital gets moved to either Fairbanks or Anchorage and Alaska builds its own freeway system will an interstate serve its capital.

They do.

Actually, both Fairbanks and Anchorage have interstates now; they just aren't signed.  Also note that Alaska is exempt from any conformance with interstate standards, and many of its interstates are two lane roads with no access control.

That's how the existing paper Interstates in Alaska are listed in FHWA's Interstate log.  Puerto Rico's paper Interstates have a PRI prefix.

If Puerto Rico becomes a state, then San Juan would be another capital served by an interstate, as some of its paper interstates are on the San Juan Freeways.  I believe PR 26 (Baldiority de Castro Expressway) is one of them, and that terminates in the City Limits.

If it wasn't for the Kingdom City developments that would fight a necessary bypass, I'd almost expect US 54 to become an I-x70 before US 63.  At least in the mid 2000's, US 54 seemed to have more sections already close to interstate standards than US 63.

Trenton, NJ is interstate-less as well.  The closest it could come is if US 1 is given an I-route number, or if NJ 29 was reconstructed to eliminated the traffic lights.

WTF?  I thought Trenton was serviced by I-95, I-195, and I-295.

If you're talking about I-routes that actually enter a capital's bounderies, none of those 3 enter Trenton.  All 3 come within about a mile or two of the outlying border, but don't actually enter.

If you want to talk about routes that service a capital, then I-95 services Dover, I-70 services Jefferson City, and I-90 services Pierre.  Doesn't matter the distance, imo.

While I agree that it would be absurd to include Trenton as interstateless, it depends on how we define "serviced".  All three of those are at least a mile outside of city limits.

You're not wrong, per se, but there's a huge difference between one mile for Trenton and 30-40 miles for the other three.

How 'bout we define it as a city that's never a main control city for an Interstate? Pretty sure 195 WB is signed for Trenton.

I-70 barely enters Baltimore proper if it does at all, but Baltimore is the main control city for it towards its eastern end.

I don't think it's ever signed on pull-throughs on the mainline, but it is used as a secondary city on intersecting roads.

Anyway, saying the Interstate system doesn't serve Trenton is about as dumb as saying commercial airlines don't serve Washington, DC.

[Kacie Jane]

Agreed.

I-195 west terminates in Hamilton, NJ at the junction of I-295. Once past I-295, it becomes NJ Route 29 north. The expressway portion of NJ Route 29 ends near the base of Arm & Hammer Park (formerly Waterfront Park at Samuel J. Plumeri, Sr. Field).

NJ Route 29 North, at the south end of the "tunnel", with the Delaware River out of frame and off to the left. The expressway portion basically ends here.


At mile 2.8 of southbound NJ Route 29. This is adjacent to Arm & Hammer Field. The expressway part picks up on the south side of the "tunnel".
