A tunnel boring machine (TBM) will be assembled in a 65-foot pit on the South Island of the HRBT. It will measure the length of a football field. The TBM will launch from the South Island, bore a tunnel to the North Island, turn, and then bore a parallel tunnel back to the South Island. Click on the demonstration video below to see how a TBM operates.
