From today's Post-Gazette:

The 500-ton cylindrical drill that will carve its way from the North Shore to the new Gateway Station, Downtown, and back began its journey slowly yesterday.

The massive machine, strapped into a red gantry crane, was lifted up, then carried forward as the crane inched its way along a red steel track into the starting pit opposite PNC Park.

Construction workers snapped photos with cameras and cell phones, but to uninitiated observers, it was almost impossible to tell it was moving.




So . . . now we know that this is definitely a Port Authority project.
