PIC: A machine designed to dig tunnels is gonna get dirty. Here’s how dirty.
When our tunnel boring machine Mackenzie finished digging the Euclid Creek Tunnel late last month, she did so on-line, ahead of schedule, and under budget.
It’s likely some of the money she saved will go towards a new paint job.
Digging through three miles of shale 200 feet under Cleveland left our boring machine cutterhead with a few scratches, but that’s normal according to our Director of Engineering Kellie Rotunno. In fact, she reported to our Board of Trustees yesterday that the rock was “very cooperative” and Mackenzie’s cutterhead was in good shape considering the length of her journey.
