2-Year Journey Complete!

The little over a 2-year journey for MamaJo is complete! She reached her destination at Foster Park. In our offices at City Utilities, we’ve followed her journey by coloring in her locations through the project, and this week – we were able to color the last connection.

MamaJo’s completion has some impressive stats:

  • Journey of 24,519 feet (nearly 5 miles) of the tunnel dug
  • 14 million tons (28 billion pounds) of material mined
  • 4,878 concrete rings; each consists of six segments

Meanwhile, at drop shaft #5 (Thieme Drive), crews spent the week compacting and backfilling the nearly four-story structure built under the street.  Photo from June 29, 2021.
