This is in eastern Knoxville TN -

You are on US 11E south, US 25W north, US 70 west, and unsigned TN 9 north.  The sign says TN 168 west is to the left.

TN 168 east is also (unsigned) straight ahead.

TN 168 was extended over US 11E-70 when US 25W was moved to I-40 and 640.  Though not necessary, TN 9 was also moved with it.  Thus there was no state designation on US 11E-70 west of I-40.  They put TN 168 on it.  Maps show this and there is a TN 168 mile posting at the US 11E-11W split -

So while not posted, it does exist on a 0.9 mile stretch of highway in Tennessee.

I'm glad you remembered that post.  In my opinion, it was the most earth-shattering discovery on this site, yet it went almost completely unnoticed.

I decided to draw it, because I usually need a visual aid for stuff like this:

Thank you for doing this map and thanks to Mapmikey and the previous posters for finding this. Wow! I agree this is a road geek holy grail to find the one place where you can go on all four directions at one time.

What does the official Tennessee state map for Knox County show here? Does it show 168, or another hidden state route?

Knox County map shows 168 doing what the map drawn above shows:

It was an unnecessary result.  They didn't have to move TN 9 onto I-640 with US 25W but they did.

Also GMSV shows a 168 mile marker -,-83.874386,3a,37.5y,87.28h,88.18t/data=!3m6!1e1!3m4!1sf3nWBlGxEmcrpanSJApfiA!2e0!7i16384!8i8192?shorturl=1

Just looked at the Knox County map and the Knoxville city map...both shows 168 doing exactly what the hand-drawn map is showing...there is also the unsigned SR 9 as well

Here's the weirdest concurrency in the country.

I win the thread.
