Most important 3di?

[hbelkins]

I-135 in Kansas.

I'd argue that 335 is more important than 135, because it's part of the Kansas Turnpike and links Wichita to the state capital.

[empirestate]

While it probably wouldn't win nationwide, you could make a strong argument for I-495 (NY). After all, it is the only Interstate serving what's essentially the 7th New England state.

[Charles2]

If I didn't vote for I-285 around Atlanta, I would probably vote for I-270 around St. Louis.

[hotdogPi]

I-285 added.

[Grzrd]

As of the time of this post, I-366 has garnered seven votes as the unchallenged Fictional Highways candidate. In the spirit of healthy competition, I suggest that I-438, the suggested 3di redesignation of a truly visionary transcontinental 2di, be added to the list. A transcontinental 3di merits consideration.

476 is the backbone of my daily commute so I had to vote for it. Its addition to the highway system in this region was a big boon. I couldn't imagine having to traverse PA 320 or have to cut through Philly every day to get to work.

[CNGL-Leudimin]

If I-366 is in the list, then I-338 (The best proposal ever) should be there.

Having previously lived in L.A. and Chicago, I'm having a hard time deciding between I-405 and I-294.

Prior to late December 1991; many commuters in the Greater Philly area indeed did just such.

Every time I'm in KC, I'm always on I-435, regardless of what I'm doing there.

[kkt]

I put I-580 (California), because if it disappeared tomorrow there's not a good alternative.  Via I-80, way the hell out of the way, or via Pacheco Pass, way out of the way as well as too small for the traffic it has already.

I-135 in Kansas.

I'd argue that 335 is more important than 135, because it's part of the Kansas Turnpike and links Wichita to the state capital.

335 is a ghost town, though. The majority of Kansas Turnpike traffic leaves at Emporia.

I-135 serves a more regional purpose, linking Wichita and points south to western Kansas and central Nebraska (i.e. I-80 at York).

Any 3dI that was originally a suffixed 2dI should be an option in the poll.

Yes, I-335 is quite empty. But I bet it wouldn't be so empty if it weren't tolled. When I head north, I exit at Emporia and go through downtown KC, just so the toll will be cheaper, even though there's greater risk of hitting traffic through downtown.

I-135 shouldn't be an Interstate because US-81. History be darned.

[bugo]

You don't have to go through downtown KC if you take I-35. I-435 is easily accesable from I-35.

Fuck I-670 (OH).

Fuck I-670 (OH).

Yeah I'm not trying to claim that should be in the poll.  It only barely counts under the criterion I put forward, subject to interpretation.  What I had in mind was I-70S/270 MD (which I voted for), I-35W/135 KS, I-80N/480 OH.  (That last one was a thing, right?)  Are there others I'm not remembering?

In an alternate reality where I-10 through NOLA was originally I-10S and then changed to I-x10, it could have been a front runner.

There was I-80N in Iowa, which connected I-29 and I-80 in northern Pottawattamie County, Iowa, which is now I-680.  I wouldn't call I-680 important in the overall scheme of things, though.  I-680 in Iowa and Nebraska should really be 2 different 3di's, the original I-680 which is the Omaha bypass, and the original I-80N, which functions primarily as the Sioux City-Des Moines connector, although I do know some North Omaha people going east will use it.  I've driven the eastern part of I-680 end to end twice, and I have never seen much traffic on it.

I-276 should get an honorable mention as it helps connect the NJ turnpike with points west.

[sandwalk]

Another honorable mention would perhaps be I-280 in Ohio.  It's a gateway to-and-from Detroit & Michigan, allowing travelers coming from the east along I-80 & I-90 (Cleveland and Northeastern cities) to bypass the snake-like I-75 through Toledo.

True, but some of the traffic between Detroit and places east of Buffalo might prefer to go north of Lake Erie instead.

I-390 (NY), maybe? Major connector between the Rochester area and the Southern Tier.

Uh, guys...I'm as much of a hometown booster as anybody, but I have a really hard time making a case for I-390 (or I-280, for that matter) as the most important 3di. Heck, I couldn't even convince myself of I-495...

(For the record, my vote would probably be for the 405, or maybe 285 or the Capital Beltway.)

[nwi_navigator_1181]

Gotta give some love to I-196 (MI).

It covers a long distance (80 miles from I-94 to I-96) and serves as a major link from Chicago to Grand Rapids and makes a decent alternative for those who want to get to Lansing (in lieu of I-94/69).

[xotoxi]

I-238...

Because it is the only 3di that doesn't need a parent.
