Well... They haven't been back to finish the tower. It's still looks the same today as it does when I took those pictures. According to someone from Reddit, which I shall take with a grain of salt, the crew made various safety violations on that tower and that they were probably kicked out of the market. So maybe that's why it remains unfinished? It does seem weird that they just up and left leaving wires just hanging.
This is the photo I posted in /r/CellTowers
Side note: I noticed Band 5 LTE going away in some areas. A tower in Bittinger, MD previously had Band 5 LTE and now it no longer does. It still has band 2 and 17 and no aggregation, at least not with my phone. I think it used CA with my ZTE MF288 modem. The Band 2 has 15 MHz bandwidth and hits 80 Mbps no problem.
