Looks like it was finished in March 2013: Niagara Tunnel Project - Wikipedia, the free encyclopedia and the reason it was moved was that the original route had too much soft rock.They moved into harder rock.

Part of the story left out there. They were supposed to have stayed in the hard rock from day one but the contractor took a "money making" detour into the soft rock.Then back to the hard rock after the cave ins.
