A. Smallest Total For Smallest Mileage Sum
My first guess is Georgia:
I-24 (4 miles) + I-59 (20.67 miles) = 24.67 miles

Do the 2dis have to intersect in the state? If so, GA beats even HI (leaving aside whether the single-digit H- routes should be counted as 2dis). If not, H-2 and H-3 sum to about 23.6 miles.

No intersection required. Although, if someone wants to take the extra step of requiring an intersection ... then by all means have at it!
-I-495/I-95 on the DC beltway go into the actual district for only a few hundred feet while on the Woodrow Wilson Bridge
-NY 17/Future I-86 dips into Pennsylvania for about a 1/4 mile

To go back to the original question, I-66 spends what, 2 miles in DC? So between 66 and 95, DC only has a full 2.5 miles of 2di!
Ian: he's looking for two 2dis...both of your examples are only one.
Now with no-intersection required, then DC winds hands-down with I-66 (~1.2mi) + I-95 (~0.1mi) = 1.3mi
Excluding DC, I'd hazard a bet that the Georgia example cited is the winner.

Apologies for poor phrasing of question. The two 2dis must be in the SAME state (in my example, Georgia).

I think D.C. is winner (great immediate observation), BUT I will exclude it because it is a federal district and not a state. :sombrero:

Does I-80 reach New York City? I thought it multiplexed with I-95 across the Hudson. If so then I-80 and I-78 in New York must give DC a run for it's money.

No it ends at I-95 around Fort Lee, NJ. It's just that some of the map-making people like to screw that up :wow:

And I-78 really has no business entering New York anyhow, given the state of the approaches to the Holland Tunnel on the New Jersey side. Certain roadgeeks who insist that I-676 is two separate routes, because of one traffic light at the Philadelphia end of the bridge, but accept the purported I-78 in New York without question ought to re-examine their standards. :-)

Again, poorly phrased on my part. (1) Find a state; (2) Identify all of its 2di Interstates; (3) Figure out total mileage for each 2di; (4) Identify 2 smallest numbers; (5) Find sum of 2 smallest numbers; (6) Repeat for other 49 states; (7) Which state has greatest sum?

For the shortest combo of 2dis in any given state, what is the largest milage compared to other shortest-2di-combos-in-a-state?

first we find a state-named I-78 New York shield. then we continue this discussion!
QuoteHaving said that, once I-99 is complete, that and I-78 in NY would be a contender (though not as short as DC I presume)!
Once I-99 is complete, you'd have I-99 (~12.5mi) + I-78 (0.5mi) = 13mi. Which would make it shorter than the Georgia example. Until then, you have I-95 (~23.5mi) + I-78 (0.5mi) = 24mi, which is still (just barely) shorter than Georgia, so looks like New York takes the kudos.
The West Virginia example suggested: I-70 (~14.2mi) + I-81 (~26.0mi) = ~40.2mi
The Maryland example suggested: I-81 (12.08mi) + I-97 (17.62mi) = 29.7mi
This one's no longer true, but back in 2002 when Alex got the figures for the Interstate Guide on the main AARoads site (http://www.interstate-guide.com/index.html), you had this in Missouri:
I-72: 2.04 mi
I-64: 14.69mi
Total: 16.73 mi - which was probably first at the time.
Now that I-64 has been extended
I-72: 2.04 mi
I-57: 21.96 mi
Total: 24 mi
So, until I-99 is extended, we have a tie between Missouri and New York.
What about I-684 in Westchester County, NY? It runs in Connecticut without a junction. I'm not sure of the mileage though...
Rough estimates:
OHIO:
I-277 -- 3.9 Miles
I-490 -- 2.4 Miles
TOTAL - 6.3 MILES
INDIANA:
I-275 -- 3.2 Miles
I-865 -- 4.6 Miles
TOTAL - 7.8 MILES
Crap, I didn't see the 2di rule. Oh well, these probably are close to being the shortest states for 3-dis nationwide.
3-digit Interstate routes aren't applicable, per the original poster.
The shortest two 2dis in Delaware are I-95 (23.43 miles) and there is nothing else (0.00 miles). Total: 23.43 miles.
Does that count? :sombrero:

If they can beat I-99 extension timewise, then Tennessee is still in running for "temporary title". If TDOT surprises us and opts to tie-in I-22 to I-240 (recommendation to be released in October), then they would have 18.75 to 19 miles. I-55 (12.28) + I-22 (approx. 6.5). But, they could then "blow it" by multiplexing I-22 to (ironically enough) I-55 for a tidy 2di to 2di connection.
Right now, Tennessee is at around 70.
I-55: 12.28
I-26: approx 57
Total: 69.28 (give or take a mile or two)

Glancing at a map of Memphis circa 2000, it looks like, at the time, part of U.S.78/ Lamar Avenue Corridor closest to Mississippi state line was in area "reserved for Memphis annexation" and that the rest of the corridor was already within the Memphis city limits. Assume for sake of argument that "reserved" part of city limits is part of city limits (I'd be interested to know if Memphis has already annexed that area). If TDOT opts for I-22/ I-240 "tie-in", then Memphis would have two 2di Interstates (I-55 and I-22) whose entire distance within Tennessee would be within the Memphis city limits.
Are there any cities in the country that currently have at least two 2di Interstates whose entire distance within that city's state are within that city's city limits?

But all except maybe H-201 stray outside Honolulu's "urban area boundary," which is what the state and the Census Bureau use to differentiate between Honolulu and all the other communities within Honolulu County. Hawaii has no municipal governments below the county level, and so doesn't have conventional "city limits" (or signs marking the city/urban area boundaries).

Looking for info re Puerto Rico's interstates, I stumbled across FHWA's interstate mileage log yesterday:
http://www.fhwa.dot.gov/reports/routefinder/table3.cfm
So, simply for the historical record:
Exact length for D.C.: I-66 (1.48) + I-95 (0.11) = 1.59 mi
Revised length for Georgia: I-59 (20.67) + I-24 (4.10) = 24.77 mi
Quote from: froggie on September 02, 2010, 04:42:47 PM
you have I-95 (~23.5mi) + I-78 (0.5mi) = 24mi.
Tie between NY and Mizzou confirmed: I-95 in NY is listed as 23.50 miles.
I wonder if either state's DOT will throw the red challenge bag and demand a "survey under review"? :D
List is as of Oct. 2002; no total for TN I-26.

"Do the 2dis have to intersect in the state? If so, GA beats even HI (leaving aside whether the single-digit H- routes should be counted as 2dis). If not, H-2 and H-3 sum to about 23.6 miles."
Upon further FHWA review...
H-2 (8.33) + H-3 (15.32) = 23.65 mi.
So, HI beats the NY-MO tie by a whopping 0.35 mi.
In "longest" shortest sum category (using the 2002 FHWA table):
Gold: South Dakota with I-90 (412.76) + I-29 (252.50) = 665.26 mi
Silver: Kansas with I-70 (424.15) + I-35 (233.51) = 659.66 mi
Bronze: Montana with I-15 (396.03) + I-94 (249.15) = 645.18 mi
Who says the Bowl System is better than a playoff? [sorry, first full Saturday of college football] :hyper:
Even though Georgia could not earn gold, silver, or bronze, home-state pride compels me to (to borrow a phrase) commend their performance as "most exceptional". A mere 1.13 mi. from winning the gold outright ...
