Weird fractions on distance signs

[Pink Jazz]

I would like to know of some examples of weird fractions on distance signs.  Typically distance signs use halves or quarters with fractions, with occasional use of thirds.  I would like to know some examples of any distance signs that doesn't use halves, quarters, or thirds.

I remember in Albuquerque there was a sign that had distance of 6/10 mile south of Downtown on I-25 northbound.

Minnesota, on warning sign plaques.

There used to be a sign on westbound I-66 stating the exit for I-495 was 1/10 of a mile ahead. The sign is no longer there.

I have seen 3/8 somewhere on MA 128.

Here's another "1/8 MILE" on southbound US 101 near Palo Alto...



Unfortunately, this sign was replaced when Caltrans added a second HOV lane on 101.  The distance message was removed and only a down arrow remains.

I've seen 2/10 somewhere recently.  Why not 1/4, I don't know. 

1/8, being binary, seems intuitive to me.

Eighths of miles aren't all that rare.  What's less common, but not unheard of, is to display distances in feet.

I have seen "800 feet".

[ekt8750]

There's a tons of tenths around Philly esp on 76, 676 and on Woodhaven Road. I think they were in place for a potential conversion to metric which had been tossed around a lot in the 70s 80s and 90s.

The math nerd in me gets put off by the fact that they aren't reduced fractions. All 2/10, 4/10, 6/10.

[1995hoo]

I've seen 2/10 somewhere recently.  Why not 1/4, I don't know. 

1/8, being binary, seems intuitive to me. 

Probably because 2/10 is 1/5, rather than 1/4. 

Thinking about it from a practical standpoint, I kind of like the idea of tenths because that's what a car's odometer or trip meter displays.

[Alex4897]

There's a few ^x/₈ signs on US 30 in Lancaster IIRC.

1/5 and 1/4 are, for all practical purposes on the highway, the same.  Why Philly uses 2/10 rather than 1/4, who knows.

[Takumi]

Long ago there was a 1/5 mile sign somewhere on I-95 between Richmond and Ashland.

[CNGL-Leudimin]

My country is full of 5/8 and 5/16 of mile signs ...

Except we sign those as 1000 m and 500 m .

Yeah, but after 1/2, 1/4 is people's favorite fraction, and it's close enough (there is plenty of evidence out there that .05 mile is within the margin of error for exit distances).

That's the answer right there.

It was very common in the 60s and early 70s for NYSDOT to use tenth miles, especially on overhead signs at cloverleaf interchanges.  There used to be a button copy sign from the mid 1980s on NY 12 north in Utica that said "JCT (8) 1/3 MILE".  It was the only instance I remember of seeing 1/3 mile.

Here's another BGS with a 1/3 MILE listing.

1/3 is not that rare (although probably rarer than eighths).

[formulanone]

There's a bunch of "1/3 mile" signs on I-57 north of Champaign. Since 1/3 mile is vaguely close to 1/2 kilometer, I wonder if they were chosen for possible future metrication purposes?



I-95 just south of Daytona Beach; for US 92 near the I-4 interchange:



There's a similar one for FL 44, but oddly using 3/10 of a mile:

[Pink Jazz]

1/3 is not that rare (although probably rarer than eighths).

I recall seeing more thirds than eighths, and if you read my OP, I don't consider them unusual.

[kphoger]

Still waiting for a picture of ^x/₆ or ^x/₇ . . .
