Just got back from a trip from OKC to Indianapolis. Had some extra time, so I took the scenic route from Tulsa to Springfield via Hiwassee. The piers and end walls are in at the western junction of AR72 and I49. The beams are sitting to the side awaiting placement. It looked as if the ramps and roadbed was cleared north of the overpass, but there was too much mud for me to investigate further.
The overpass at AR279 is nearly complete (just lacked the guardrails). There is a parallel road just to the south of 49 that runs over to the eastern junction with AR72. It gave me an opportunity to get a good look at the roadbed. It's ready for paving.
The AR72 overpass south of Hiwassee is complete. It was made for 4 lanes, but only two were paved on either side (the approaches of course).

I have some pics that I will try to post later this week.
