Highway Oddities

[Voyager]

Other than Interstate 238, which other highways have oddities in them, or are oddities in themselves?

Interstate 84 in Oregon and Connecticut is one example.

[agentsteel53]

why is 84 an oddity? because it appears twice?  or because Conn I-84 in the western half of the state goes back to 1952 and is comically substandard?

[Voyager]

Just because they have the same number and they were never connected. Like the two interstate 76's. Interstate 99 is a good example.

[Darkchylde]

I-95 strikes me as a better example of that sort of oddity... here it is, 2009, and its two parts are still unconnected through Jersey.

[Alex]

This doesn't happen too often, where a road changes numbers without intersecting anything.

[agentsteel53]

similarly, I-290 changes to I-395 at the Mass Pike, but without intersecting it.

Here is another highway oddity:

More on this odd find here.

Not only do they contradict each other, but they're both going south here.

*shudder*

There have been times where I've had to stop at the on-ramps and consult the map because I could not, for the life of me, remember which way was "south".

I've read they want to construct an interchange with the I-276 Pennsylvania Turnpike and divert the I-95 south of Trenton to the NJ Turnpike. I wonder which number the existing part west and north of Trenton would get.

Don't forget the OK 20/AR 43 (mis-signed as MO 43) oddity.

As for layout oddities, I present US 77 in Ardmore, OK, aka Commerce Street. Four lane divided street with service roads and on and off ramps. Yes, you heard that correctly.



Arrows show the preferred method of making turns onto the cross street for northbound traffic and turns onto Commerce for westbound traffic on the cross street.

Here's a Google Street View shot of how it looks from the ground. I need to get a better shot of it, but my camera is lost...maybe next time I go down there.

[agentsteel53]

that 11 green sign is long gone, right?

[Voyager]

Nope, last I heard it was still there.

At first, it was supposed to be an extension of I-295 from its current end at U.S. 1.  The latest is that it would be an extension of I-195 from the existing I-195/I-295 interchange, overtaking the northerly 8 miles of I-295.

Personally, considering the cardinal direction changes and the similarity between "295" and "to 95" that the Trenton Loop has experienced in the last 20-odd years, it should be given its own number (such as 895) rather than an extension of an existing number.

[Alex]

Well all states want to do is extend existing numbers rather than make new ones, so I see Interstate 195 being extended. 

[agentsteel53]

really?  at what cross street?

[deathtopumpkins]

really?  at what cross street?

You're referring to the road I mentioned, correct?

[agentsteel53]

no, I refer to this photo:



the title of the image is Anaheim Street at 110, and I looked there about two years ago and found nothing.  But this is Joel we're talking about, so he may very well have biffed the cross street.

[Alex]

Most of Joel's images (and webpages) are severely outdated, so expect all of those errors to have long since been corrected. He was going to start http://www.goldenstatehwys.net/ in more recent times, but as you can see by clicking, it still states opening soon (been that way since 2006!)

[agentsteel53]

sweet technological Jesus, what font is he using??

[deathtopumpkins]

I got a weird highway oddity. None of the 3dis of I-78 east of NYC actually interchange with I-78 itself. The closest any of them come is I-478, whose terminus, the Brooklyn-battery tunnel is just a little way down NY-9A from I-78's terminus, the Holland Tunnel. But they never actually meet. I wonder who's genuis idea it was to do that...

[agentsteel53]

was 78 supposed to be extended?  495 was supposed to go under Manhattan.  Here is an optimistic trailblazer on the west side of the island!

[Chris]

Well, they don't have an I-478 for nothing. I believe it was supposed to run all the way on Long Island.

[ComputerGuy]

WA-100 ends at itself, about 2 miles south of its western terminus! It is also the only highway in Washington not to use a cardinal direction (north, south, east, west), but uses the direction "LOOP".
