City of Fort Wayne Utilities news release announcing the passing of the halfway point on MamaJo’s underground journey.
MamaJo reaches the halfway point
Fort Wayne, Indiana (August 20, 2020) – MamaJo is halfway home! At 3:45 this morning (August 20, 2020) she pounded through bedrock, hitting the milestone nearly 2.5 miles between the bridge at Van Buren Street and the Norfolk Southern railroad bridge.
MamaJo is the deep rock tunnel boring machine that is digging the deep rock sewer tunnel, nearly 5 miles long, at a 20-foot diameter and more than 200 feet below the earth’s surface.
The name MamaJo comes from the first two letters of each of our rivers, Ma from the St. Marys, Ma from the Maumee and Jo from the St. Joseph.
When completed, the tunnel will keep a billion gallons of combined sewage from flowing into our rivers.
