MamaJo is getting closer to the end of her journey. Today she’s between Illsley Drive and Rudisill Boulevard. Below is a photo taken inside the tunnel on June 21. You can see the concrete slabs in place that form the ring. The pipes on the left are pulling crushed stone out of the tunnel. The yellow tube above supplies air.
Work at drop shaft 5 (Thieme Drive) shows stone being dumped for backfill, and on the right, you see a machine compacting the backfill. Week of June 21-25, 2021
