71

They didn't have anywhere else they needed to go.

[I-55]

They didn't have anywhere else they needed to go.

I think some of us can agree that I-76 (e) could use an extension westward and/or eastward. I-79 has nowhere to go unless its routed along Corridor L to I-75 (which will never happen), I-71 has been discussed on this forum to overtake the WK Parkway to I-69 (or I-24), and I-78, along with everything not stated above, is short because it has nowhere else to go without pipe dream extensions.

The only interstates that were designed for long distances are the x5s, x0s, I-64 (defacto I-50/60), I-94 (effectively a second I-90), I-84w (no x0s in grid), I-77 (no x5s in the grid), and congressional/coalition designated corridors like I-69, I-29/49, I-57 and I-14 (which doesn't nearly fully exist yet). Other than that, most other interstates are short city connectors that don't need to go very far, and if they went further they'd be in the middle of nowhere or redundant to another interstate highway. Many routes are restricted by geography, particularly in the northeast. The extra distance isn't needed and often the interstate has nowhere to go.

Another bit about I-76: I’m pretty sure both the Eastern and Western branches were originally I-80S/branch routes from I-80. They became I-76s in 1976 - celebrating the Republic making it 200 years

[TheDon102]

I-78 was supposed to be a longer route but it was (mostly) cancelled in New York City so....

What

What

What the OP is saying is that the four Interstates mentioned aren't that long, unlike some others such as I-44, I-64, and I-81 (deliberately excluding the multiples of 5). However, the OP, in both this thread and in others, keeps using words that don't refer to length, sometimes confusing it with width and sometimes just being ambiguous.

[kinupanda]

Why are those highways so small I love those highways but they're so small. Why is that?

They're doing the best they can.

[zzcarp]

I-71 occurs as the right length. It parallels US 42 and shares the same cities (Cleveland, Louisville) for its termini.

I-76, formerly I-80S, has had extensions proposed at both ends. In Ohio, I-80S on some early planning documents was to diverge from I-80/90/Ohio Turnpike at the US 250 exit at Milan and follow the US 250 and US 224 corridors to the current I-76 west terminus at I-71. None of this corridor past Lodi was improved, and it's been removed from planning documents for over 50 years.

On its eastern end, it's been proposed and studied to extend I-76 down the Atlantic City Expressway. My understanding is that NJDOT believes it could cause motorist confusion and that there's no benefit to doing it. There are likely substandard design features that would need upgraded before it could be signed newly as an Interstate.

Re I-79, south of Charleston there is only one freeway corridor through the mountains.  I-77 'won' the designation as it supplanted/parallels historic US 21 its entire length.

[ethanhopkin14]

A more reasonable question would be why are I-30 and I-45 so small (short)?

Just curious, where would you extend I-76(E) from it's western terminus?

The most common proposal I've seen is to Fort Wayne.

It sure would be nice to extend it to Chicago and connect it to I-80.

Is it like driving a car on a bike lane?  Like the pavement isn't wide enough for a car?

At least in the Holland Tunnel

Multiple roadgeek pipedreams for I-76 E have it going south on I-71 to Mansfield, Ohio and then following US 30 west to somewhere (depending on the proposal) near Chicago.

Why are 95, 5, and 75 so tall?

[thspfc]

I don't know but I-80 and I-90 are so big.

This guy gets it

[jmacswimmer]

I-15 & I-35 would like a word.

how 'bout...

• I-69: legislative silliness
• I-76: "named highway X should be an interstate!" (see: Atlantic City Expressway, NJ Tpk from exits 1-6)
• I-86: interstates for interstates' sake
• I-99: grid? what grid?
