Heading to Quad Cites for the road meet, I hit some road work along I-80 east of Des Moines. The westbound lanes were converted to two-way traffic while the eastbound lanes were for oversized loads only, but not everyone followed directions.

Looks like a standard split/merge arrangement, with one direction having one lane on each carriageway. I've never seen one with signing specifically indicating the rightmost split lane is for oversized loads only (or local traffic only).

I think MN is doing something similar on the I-94 reconstruction east of Rogers.

The temporary setup was one express lane running counter flow, and two lanes on the original side. I don't remember any designations for oversized vehicles. The expansion is complete now.

I think I've previously encountered a similar setup in some other state as well. Maybe I-65 in Kentucky? Can't recall if there was one or two lanes left on the original carriageway though.
Sometimes this is done at interchanges to keep people from using them for u-turns. Iowa also uses breakaway markers to do this as well, placing them close together at interchanges.
Caltrans has been getting big on this in freeway construction zones. I prefer to stay right in them given there is actual access to freeway exits that the left lane/s can't get to. Atwater and Madera come to mind as infamous temporary choke points via this temporary setup on CA 99.
ISTHA has been doing this on both the Tri-State now and the Northwest tollway back in the oughts
IDOT did this in the Chicago Loop with the Kennedy at the rapid fire ramps
INDOT is doing this on the Borman - and has done so multiple times.
