Cutter Head Demobilized in Lorain!

May 13, 2014

Earlier today, crews working on the Black River Tunnel Project lifted the 232,000 lb cutter head out of the receiving shaft . Over the next couple of weeks, they will continue disassembling the TBM and the conveyor system. After the TBM is completely demobilized, a secondary monolithic poured, cast-in-place, concrete tunnel liner will be installed to complete the storage tunnel.
