Most important 3di?

[hotdogPi]

What is the most important 3di? If I forgot one that might be considered the most important, I will add it to the poll.

You are allowed to change your vote at any time.

Things that I will NOT add to the poll:

1. US routes, state routes, and roads outside the United States. "3di" means "3 digit Interstate".
2. 2dis with a leading 0 (like I-095).
3. Interstates created solely by FritzOwl.

Duh! The only one where a forum member here has allowed us to drive 85 mph!

And where's Interstate 180 (Illinois)? How did you forget it... 

[national highway 1]

I-580 in California? It connects the Bay Area to I-5 and southern California

[hbelkins]

I-270 Maryland should be on the list.

[NE2]

I-495 (PA), all ramp of it.

[SectorZ]

You missed a pretty important part 495, the one you live closest to.

I-710 and I-880 these are truckers freeways. As in access to the port of Oakland and Port of Los Angeles and Long Beach.

Funny to see 238 on the list and not 580. Also funny to see 278 and not 678 in NYC. My vote is for 610 in Houston, only way to cross downtown Houston without crashing.

I-495 (PA), all ramp of it.

Nope.  It was edged out by I-684 in CT and I-587.

[bing101]

I-680 California, I-210 California and I-280 California have significance too,

[english si]

I-180 (WY) is so important that they overlooked the poor standards just to get the link on the Interstate network!

I295 in NJ is fairly important as it provides a bypass for traffic going around philly that do not want to pay a toll for the turnpike.

[hotdogPi]

By request, 580 has been added to the list.

[wxfree]

I-095, that's great!  I nominate I-35E (I Three Fifty E).

[Zeffy]

Looking at the list, I would have to say either I-405 or I-495. I just can't figure out which one is more important though. By important, are we talking about how if the road were to spontaneously explode into a trillion pieces, traffic problems would overflow onto surrounding roadways?

[jeffandnicole]

When can we nominate a 4 digit di?  I'll put H201 up there as the most important.

[SteveG1988]

I270 In Mayland. It connects 70 to the DC Metro Area, bypassing baltimore in the process. I think that should be on the list.

[hotdogPi]

I-270 has been added to the poll.

[bugo]

I-444

[slorydn1]

What, no I-290 (IL)?  Ike would not be happy his Interstate isn't on the list, LOL.

[Gnutella]

I-476. It connects three of the five largest metropolitan areas in Pennsylvania.

[adventurernumber1]

I initially thought it'd have to be Interstate 495 (The Capital Beltway), and that's what I voted (but I cannot figure out how to change my vote). But now that I think about it, if I-495 were to just disappear, Interstate 95 would still keep the eastern part of the beltway in business, and I didn't think about the fact that there's still a few limited-access arterials within the beltway. Though I-495 is a very important interstate indeed, I have changed my mind about thinking it'd be the most important 3di. I'm now inclined to say that Interstate 476 could be the most important 3di. It's length says a lot to begin with, and it connects Philadelphia, Allentown, & the Scranton/Wilkes-Barre area. It is also important in serving the western side of the Philadelphia area. Though, very close runner-ups are Interstate 580 (it connects Northbound I-5 traffic to the Bay Area, it importantly serves Oakland, runs along the Richmond-San Rafael Bridge, and more), Interstate 405 (we all know how bad its traffic is to prove it), and I-287 (serving as a partial beltway for the largest metro area in the country, not much else needs to be said).

I-135 in Kansas.

[Zzonkmiles]

I would nominate I-285 in Atlanta to be added to the list. The traffic volumes are incredible. Without this beltway, traffic in and around Atlanta would grind to a standstill.

But out of the available options, I voted for I-495 in DC. You've got several military bases, the HQ of the federal government, the Washington and Baltimore metro areas, and all the long-distance traffic competing for space here.
