Niagara Tunnel All Smiles

Well, tomorrow may be breakthrough day.  Actually, it just breaks into the smaller diameter grouted tunnel, which acts somewhat as a pilot hole.  After that, the TBM reams out a few hundred meters along the hole.

I have nothing to say from my twisted mind.  It's a wonderful thing that nobody was killed, and willful ignorance will keep us away from true costs and incomes.  :)
