3di's that are longer than their state's portion of the associated 2di

[KCRoadFan]

For me, this is post number 495, which made me think about how I-495 in Massachusetts, aside from being the longest 3-digit interstate at 120 miles, is longer than the state's section of I-95, which is only 91 miles.

Throughout the country, are there any other 3di's that cover a greater distance than the 2di's with which they are associated travel within the state? (I doubt it, but at least we can try.)

269 in Memphis metro works for both I-69 in MS and TN.

I-269: 45 miles
I-69 TN: 21 miles, but unsigned
I-69 MS: 23 miles

US 395 has way more mileage in California than US 95.

[TheHighwayMan3561]

Does this count the 3dis that enter a state their parents don't?

[LilianaUwU]

US 395 has way more mileage in California than US 95.

On a similar note, US 191 in general is longer than US 91.

3di = 3-digit Interstate. There are way too many examples with US routes.

Extreme examples:  I-295, I-395, and I-695 in DC; and all the x78's in NY.

The OP didn't specify so I went with the answer that popped into my head.  Had I thought of a 3d State Route longer than it's parent I probably would have gone with that instead.

Yes, the OP specified.

...are there any other 3di's...

Yes, I read the original post.  He discussed an Interstate example but didn't clearly convey US Routes and other highways were to be omitted.  I'm sure this thread won't be flooded with US Route examples, so I don't get why you're making such a big deal out of it.

The same happens with another I-95/I-495 combination:  New York (23.5 vs. 66.4 miles)

[SkyPesos]

The 3 miles of I-275 in Indiana is longer than the 0 miles of I-75 

[bassoon1986]

Also 6.9 miles of I-676 beats out the 3 miles of I-76 in New Jersey.

It's common for 3dis and 3duses to be confused.

[oscar]

The 3 miles of I-275 in Indiana is longer than the 0 miles of I-75 

The about 2.9 miles of I-129 in Nebraska exceeds the 0 miles of I-29 in Nebraska.

And the about 1.2 miles of I-535 in Wisconsin exceeds the 0 miles of I-35 in Wisconsin.

Because "3di"  means "3 digit interstate."

Anyway, I-535 in Wisconsin is longer than I-35 in Wisconsin.

Nothing in California or Nevada is very close.  I-580 and I-210 in California are probably the biggest fractions. I-280 and I-680 put together (which together form a 3/4 loop) would be closer than I-580.

I-238's 2.1 miles length is 2.1 miles longer than it's biological parent I-38 though




yes, I know I-238 is a portion of CA 238 renumbered, and is a 3di of I-80, but I can't resist making another I-238 joke in a fitting thread topic like this one.

I-238's parent interstate is I-80 which is quite a bit longer than I-238!

[jp the roadgeek]

And nobody mentioned I-287 in NJ?!?

[jmacswimmer]

Here's an interesting one: I-295 & I-95 in NJ are almost the same length now following their extensions/realignments (I-95 has the edge by a mile or 2).  Are there any other examples of a parent & child being around the same length in the same state?  Besides the low-hanging fruit of I-495 & I-95 in DC

[hotdogPi]

Non-zero example: I-155 in Tennessee

[Dirt Roads]

I-238's 2.1 miles length is 2.1 miles longer than it's biological parent I-38 though

In North Carolina, we are soon going to get I-587 at about 37 miles, which will be longer that its incomplete parent I-87 at about 13 miles.  Of course, both of these freeways are much, much longer and stuck in the underworld of Interstate standards (which aren't very important when the roads are already posted at 70MPH).

US 395 has way more mileage in California than US 95.

When US 95 used to enter WA, the state's US 395 was 513 times longer.
