Most Unnecessary Interstate

[Alps]

In hindsight, I-180 IL, but hindsight is 20/20. In terms of something that was actually unnecessary from the moment it was conceived, I will have to go with I-73.

[MCRoads]

No one has mentioned I-27 yet... it might not be totally useless as a road, but it could probably be signed as a state route, or, at most, a US route.

Along with the extensions of I-69 and I-74.

[dgolub]

I-895 in New York.  They're been talking about demolishing it for this reason.

I'll agree on the I-74 extensions, but only everything on I-69 south of Memphis.

I also agree on I-74 extension into NC and I-69 south of Memphis too.

I-175 and I-375 in FL:  essentially glorified ramp networks. 

[21stCenturyRoad]

I-381 in Bristol is more of a ramp that an actual freeway.

Everyone's picking the wrong I-180. The one in Illinois was built for legitimate reasons. The bad one is the one in Wyoming, which isn't a real freeway.

Why choose?

[jp the roadgeek]

I-12, as a 2di, is unnecessary.  Could very well survive as I-410 (I-476 in PA and I-495 in MA are both longer).

At least the Wyoming one has traffic...

Says most people who aren't familiar with either Louisiana or its early Interstate planning.  Long story short:  I-12 was not originally proposed to meet I-10 and I-59 at the same interchange.

Whats the long version of the story?

[kkt]

I'd rather have 305 signed than the 80 business loop.

I agree...

In fact now that the number  California I-480 is available again, maybe I'd make the bypass loop I-480 and restore I-80 to the original route.

Interstate 587 - Kingston, New York

[ekt8750]

I'm surprised no one has mentioned MD I-595. Hell they don't even bother to sign it.

[freebrickproductions]

One could argue the same about I-124 in Chattanooga.

[cbeach40]

I-15 south of the Alberta border. 2016 AADT of 1,924.

It's so dead you could have a one lane bridge with "yield to oncoming traffic" signs plopped down and it would still function well.

[bing101]

I-980 mainly because its a continuation of CA-24.

[jp the roadgeek]

Forgot I-790.  It's multiplexed with NY 5 and NY 12 the entire route

[myosh_tino]

I-180 (Wyoming)
I-238
I-97

I-238 is actually quite useful, despite its infamous number.  It is a major trucking route for traffic coming from I-5 coming to the Bay Area - all trucks must exit I-580 onto I-238 and take I-880 N to SF/Oakland or S to San Jose and the bridge crossings.

The number is specifically why I consider it unnecessary. I'm of the opinion just leaving it as CA-238 would have been better, although I'm aware of the history and why it was given the badge.

While I agree the number is definitely funky, an Interstate designation for that stretch of freeway is important as it provides truckers the assurance that the route they have to take to reach the Port of Oakland (because trucks are banned on I-580) is built to Interstate-standards.

[SSOWorld]

either drop I-41 or remove I-894.  Both actually - the number doesn't make the road - and here is an entry from the department of redundancy department.

I-895 in New York.  They're been talking about demolishing it for this reason.

More than talk -- it just got decommissioned at the last AASHTO meeting (details in another thread); the first step toward "boulevardization"!

Similar to that situation you have I-375 in Detroit.  Back in 2013/2014 MDOT was talking about making I-375 into a parkway but never went through with it.  My understanding was that there was supposed to be some impact survey this year to determine what to do with I-375.

Anything in southern Texas 

I was thinking that at first, but then I remembered I-35 between San Antonio and Laredo.  I wouldn't want that downgraded.
