Title: Concurrency of roads going all 4 directions?
Post by: bwana39 on May 06, 2020, 04:23:15 PM
In Texarkana, The part of 7th Street between State Line Avenue and Hickory Street where US 67 N, US 71S, and US82E are concurrent (and the opposite on its mate MLK / 8th Street)  https://goo.gl/maps/3NZUiyJxadJaorVa8

Are there any instances where a stretch of road is signed for all four directions?

No, at least in the United States. This topic has come up before.

It's the holy grail of roadgeekdom.

The only example I ever saw posted in MTR is not available in DejaNews/Google Groups because the OP had the "no archive" header enabled. At the time, I was using the Free Agent newsreader on a Zip disk, and I'm sure I saved the post in the software. I may still have that Zip disk somewhere, but have no means of retrieving the information on it.

If it happens anywhere, it will be in Arkansas.

NE2's example of a fictional I-30 business loop (see here (https://www.aaroads.com/forum/index.php?topic=14712)) is in Arkansas, so if there was one, he would have checked to see if there were any first.

It does not currently exist in the US.

We know that if it exists, it:
* Is not an erroneous sign, since hbelkins said it was just text.
* Is N/S/E/W and does not involve the former diagonal routes in Ohio (I asked him).
* Could be outside the US, but since hbelkins thought it was in Massachusetts, it's not likely to be outside the US.
* Could be something that no longer exists. If it was real, this is by far the most likely.

This is the closest thing I've seen to a four-way overlap; this only points to the directions to find the ramps, since the Express Ramp entrances are not located at every exit:

Yeah, I could imagine a pilgrimage.

I personally think it would probably confuse too many drivers for it to be posted, should it genuinely exist. I think the roundabout in Boise City, Oklahoma (https://www.google.com/maps/@36.7297274,-102.513834,18z) was the closest thing to it.

Except that I don't think there was a single point on the circle that carried all four routes.
