Lorain's 23-ft TBM Reaches Northern Shaft

April 29, 2014

We are extremely excited to announce that on April 29th our 23-ft TBM cutterhead broke through the receiving shaft wall in Lorain!  This marks a HUGE milestone for our TBM crew, and the Black River Tunnel Project.  We are very thankful for everyone's efforts in making the journey of the TBM a success.  You can read more about the hole out and view live footage here:
