Wilbur never ceases to susprise me. This afternoon when I visited
the bridge, Wilbur hollered at me. Walking over, I saw that today, he
was not Wilbur, the iron worker, not Wilbur the hydraulic man, not Wilbur
the forklift driver, but here was Wilbur the hole driller. I had watched
the High Steel guys drill and ream the bolt holes for coupling the
center edge girder to the east and west span edge girders. Here, Wilbur and
his coworkers were drilling holes to anchor the stay pipes. I asked how
the bolts would be stabilized in these holes - and Wilbur's answer - we
use red epoxy - so I made a photo of this also.
Here is Wilbur and one of his coworkers
Here is another coworker and Wilbur making holes
under the footing of the stay cable support.
Here is Wilbur - and a view (right) of the stay pipe stabilizer
And here is shown the red epoxy used to bond the bolts to the concrete wall
of the holes that Wilbur drilled.
