Has to be a city job, they couldn't even bother putting "EAST" or "WEST" on then. Also, the left center lane is an optional lane, so thru traffic can also use it, so the signs are a little misleading.

How about that- a picture from my old hometown. Most likely the signage is a Dallas county job since Belt Line Road is a county maintained thoroughfare. Haven't been through that particular intersection in probably ten years or so. That was back before the recent expansion of I-30 and the latest widening of Belt Line.
