1) Not Invented Here
2) Because it is not well understood by contractors out here, and/or
not well adapted to particular details of the local geography, the
projected costs would be way up for doing it out here. Note, for
example, that this bridge is being moved into place over completely
dry ground - freeway, in fact - that can take the load and allow workers
to access the bottom without special equipment.
