This changes west of SomSt, which can keep the same name. Other points should be:
EastSt (former US 78 eastbound)
MisBlvd?
DanThoBlvd
US61/64
and then copy from US70.

And it's now being posted in AR along I-55.

@mapcat, I recommend adding an addition point @ East/Crump, due to that being the way EB US-78 historically got onto Crump due to Crump being divided @ MLK preventing left turns.

That way, anybody who went EB on US-78 in the past, can finally claim some of Crump till they travel the new extension.

TBKS1 on the AARoads Wiki Discord reported that US 78 is signed in Jonesboro.

Roadtripping in Arkansas. I've seen US78 cosigned with quite a few routes. Western most signing started at US67 and AR226. It's signed along AR226, then US49, then I-555, then AR18S, then AR18 at least to AR119 where I got on (but I assume it goes to Blytheville from there). Decently signed, but not all turns are posted yet.
