Most 2dis clinchable in one day

[skluth]

^ Add 78 and yes it's doable in about 9 hours without traffic.  So that would be 5 in one day.

You can also use I-99 instead of I-78 in that scenario. Starting in Morgantown, you can take 68-66-97-83-99 and be back home at the end of your day.

Maybe PA's portion of I-99, but not if you go all the way to Corning.

Oops. I had forgotten they've extended Bud Shuster's pet project beyond State College. You are correct.

For a variation on this, I am looking at what's the best I can do starting at my house.

3: I-88 (I-81) I-84 (I-90,I-495,I-93) I-89 could be done in about 12 hours with really good traffic.

Closest I have come to finding a 4, but it's outside 12 hours even not factoring in traffic and stops: I-88 (NY 17/I-86)  I-99 (all signed segments) (I-76,US119) I-68 (I-70,I-81) I-66.  If I came that far in a very long day, I'd have to shoot over to Annapolis and go up I-97 to make it 5.  But then I'm way beyond the 12-hour limit.

Not a lot of short 2dis near me in Atlanta, so I'd bet my limit is probably 2.

I-24 and I-72 would take right at 12 hours.

I-22 and I-30? Nope, that's 14 hours.

I-59 and I-12 could be done in under 10 hours.

I-16 and I-4 is a crisp 9 hours, but there's nothing else to grab.

Oh! It looks like I could get I-16 and all the various pieces of I-73 and I-74 in 11 1/2 hours (counting NC's I-74 as distinct from the one in the midwest). So that's 3.

Is I-42 signed? It might be possible to drop I-16 and do 42, 87, 73, and 74.

My first thought was some combination of 68, 66, 97 and 83. I've clinched all four of them, but not sure if I got more than one on the same day.

[Max Rockatansky]

I-19, I-17 and I-11 can definitely be done in one day.  The direction of travel wouldn't require a huge amount of north/south deviation with the present form of I-11. 

[wanderer2575]

You could in one day drive all of the original I-69 from Indianapolis to Port Huron, take I-94 to I-75 to I-96 in Detroit, and drive all of I-96 to Muskegon.  Whether that counts as an I-69 clinch these days is a point of opinion.

I opened the Wikipedia list of interstates and sorted from shortest to longest and noticed that there were a couple in Arizona.  Since I'm not familiar with that area, I thought I'd try something else, and then I realized that since I-97 is the shortest 2di, a route should involve that.  I-83 and I-88 are pretty short too, so I tried to include them, and I got I-88, I-78, I-83, I-97, and I-66 in a little less than 11 hours.  The route also involves the following routes:

NY: I-81/I-86
PA: I-80, I-380, I-81
MD: I-395, I-95, I-695
DC: I-695, I-395

As an added bonus, the route also clinches I-380 in PA.

I tried including I-87, I-84 and/or I-99, but that was too long.  Since Google shows travel times based on the current time when you plan the route, starting the route at the eastern end of I-78 and including I-68 and the southern portion of I-99 may be 12 hours or a bit shorter, but it's currently 12:12.

Also, since the first route starts in Schenectady, it could work for Jim.

My first thought was 97-83-78 would be a good place to start.  Maybe add on 66 at the front and 87 at the end?  66-97-83-78-87 might be possible.

Looking around in the Midwest, my thought is that you could start at Zion, IL-ish and go N on I-41 then south on I-43.  That takes so much time already, though.  Or start in Beloit and do 43 N to 41 S to 57 S.  That's still only 3 though.

88 -> 57 -> 24 would be pushing it to hit three. Have to double back an hour or so between Sikeston and Marion, IL to do it, also

Google puts that trip at 13.5 hours - over 12 hours by the cost of the Sikeston-Marion backtrack, basically

If you want to count lettered-suffixes, then I-2, I-69E, I-69C in the Rio Grande Valley, shoot over to Laredo for I-69W and collect 'em all. Easy peasy!

Edit: It looks like you only need one border crossing, at I-69W. Google Maps puts it at about 6 hours.

Unfortunately, they're effectively 3dis with a promotion, which means they're kind of ineligible for the challenge.

Even if you try what will become the full routes, you can make it well under 12 hours. Once it's all full freeway the time would reduce significantly, especially along US 83. You might be able to throw in I-37 too, to get 5.

If we can assume a bit of (unrealistic) speeding in addition to no traffic, it's possible to clinch I-88, I-78, I-83, I-97, I-66, and I-68 in 12 hours, assuming an average speed of 71 MPH.

It might be faster to do 88, 57, and 72 in one day, although the most efficient way would not do 57 in a single segment.  Google Maps is putting that also at 13.5 hours, which includes going the distance both ways on I-72.

[kphoger]

I'm pretty sure I could do six.

I-69, I-75, I-80, I-90, I-94, I-96 and possibly I-71 and I-77 as well making it eight.

Maybe with a NASA rocket engine.  Clinch, clinch, clinch!

Well starting out I would already have I-75 clinched, then I could take I-69 back to I-475 to I-75 again to ride on I-69, then to I-94 to I-96, then down to the Ohio Turnpike to get I-80 and I-90, then east to get I-71 to I-77. I think that's reachable in one day.

That's not clinching the routes.

Then how in the heck is the I-35 example in the OP clinching that route? You aren't going to clinch I-35 in one day. It would take you about 22 hours of driving to clinch I-35.

Just in case the answer wasn't made clear enough...

What is the greatest number of 2dis that is clinchable in one day of driving? Let's cap a "day" of driving at 12 hours, since we don't want to overtax ourselves.

If you wake up in Amarillo, TX,
you can drive the length of I-27,
swing down to Copperas Cove
and take the entirety of I-14 to Belton,
then take I-35 down to San Antonio
and ride I-37 into Corpus Christi.

Only the phrases in bold type are clinches.  Note that driving from Lubbock to Copperas Cove would also likely include driving on short stretch of I-20, and entering San Antonio would briefly overlap on I-410.  Yet those Interstate numbers were never even mentioned because they wouldn't be clinches.

For me, the travel time shows up in black, which means they're using the "without traffic" time rather than calculating a live one.  For me, this happens whenever there is more than one destination on the list.

Also note that I-99 is currently discontiguous and has a piece near Corning.

[BrianP]

I figured doing 7 in about 1000 miles is possible (not in 12 hours) in a day.  Start in Schenectady, NY and end in NYC.  In order clinch 88, 99, 68, 66, 97, 83 and 78.
