Niagara Tunnel Update

This is not negative.  All that hidden money is water under the bridge.  I am calm.

They are proceeding swimmingly, as though high stresses didn't exist.  I am happy for them.  This is a picture of the overbreak-fixing carrier.  Then they go through with the slip form for the arch, and then they have 2 grout injection passes, to make sure everything is nice and tight.  In the old days, we would have had a crushable zone, but what the hey.

I'm sure this will last the full 20 years before it cracks up, which is the same for a badly maintained new nuclear plant.  Then everybody is happy fixing it up again!  :)
