Resolving conflicts between the Interstate and US highway systems

Why I-44?  Why not I-42 or I-46?  I don't like duplicating numbers.

So one day it can connect to Saint Louis.

A road that runs SW-NE changing to SE-NW?  Yeah, that makes a lot of sense.

HB: I hate "multiplex" as well.  It's anal and sounds like a movie theater.

Well I-64 loops around itself doesn't it?

Come join us in the multiplex, where we watch all the movies at the same time and assimilate you into the hive mind.

NYSDOT uses the term "overlap".

I like the Arkansas-friendly term "piggyback".

[froggie]

I've taken to using "concurrency" more and more in recent months...

That's not a bad term. 

I sometimes use "duplex" or "triplex" and so on and so forth.

[hotdogPi]

I use "concurrency" as a noun and "multiplex" as a verb.

Figures Arkansas would use a 1st grade term.

Arkansas doesn't use "piggyback".

Arkansas is more "destroy the routing" than the theatre term multiplex

The original definition of "multiplex" is actually very close to describing the phenomenon. In communications, multiplexing is "combining many signals into a single transmission circuit or channel". That's really what a concurrency is doing.

As for the theatre, that's has several consecutive concatenations, first "cinema" and "complex" to form "cineplex" and then "multiple" and "cineplex" to get "multiplex".

Since I have yet to find a DOT that actually uses "multiplex" (or "duplex", "triplex", etc), I've switched to concurrency (noun), overlap (verb), "run(ning) concurrently" (verb/adverb phrase) for in speech and writing.

I've also used the term "share pavement," as in "I-80 and I-90 share pavement across most of Indiana and Ohio.

And I still think I-41 should have been a 3di child route. 

[billtm]

I think I-41 from Milwaukee to Green Bay should be I-43W while I-43 from Milwaukee to Green Bay should be I-43E. Leave the rest of I-41 as I-94 and leave I-94 as is in Milwaukee so that I-894 can be decommissioned.

OH 7 and WV 7 almost intersect. OH 7 is the road that parallels the Ohio River from Chesapeake all the way up to near the point where the river crosses into Pennsylvania. WV 7 is an east-west route that runs from the Maryland state line to New Martinsville. It runs concurrently with WV 20 and then crosses a bridge into Ohio. The concurrency is minimally signed on the south side of downtown and not at all through the downtown area. North of downtown, at the entrance to the bridge, there is signage for Ohio 7, with both the word "Ohio" and an OH 7 marker. There is no route marker signage on the Ohio side of the river, so I don't know what hidden number the Ohio portion of the bridge and approaches might carry.

The New Martinsville Bridge is officially WV 7 and Ohio SR 536 but isn't actually signed as either route in the field.  SR 536 heads west from Ohio SR 7 just north of the bridge and has an unsigned multiplex with Ohio SR 7 down to and across the bridge.

WV 20 officially ends at WV 7 east of New Martinsville.  There isn't a multiplex between the two routes.

At its intersection with WV 2, WV 7 is signed as heading north along WV 2 towards New Martinsville but I've never seen any other signage for WV 7 between there and the state line.

WV 20 in my original post was a typo. I meant, of course, WV 2. Like you, I've seen no signage for WV 7 beyond the WV 2 intersection south of downtown, and nothing shows up on Street View.

I'd almost guess that by now the button copy "Ohio OH 7" signs have been replaced.
