I-49 will actually cut through part of Fort Chaffee, crossing AR 22 just to the west.
These bridge piers will form part of an interchange at AR 22, while this area awaits construction.
And here we have what appears to be a future ramp
Since these photos were taken back in August, more bridge piers have been constructed south of AR 22, almost up to the roadway itself. On the north side of the future interchange, not a lot has changed... or at least nothing that is visible from the road. I have seen several construction trucks traveling in and out of the area, so I'll have to sneak up there some weekend and get a better look at the progress.
