A method of constructing an elevated roadway, utilizing a crane having an
articulated boom arm and a gripping mechanism, at the end of the arm for
gripping a pylon, below a roadway cradle of the pylon, in order to
temporarily transfer loads, generated by a tramway moving a precast bridge
section along the crane arm and onto a pair of cradles, mounted upon the
pylons. The construction method permits the crane to be positioned on an
assembled portion of the elevated roadway, while constructing the
remaining portion of the elevated roadway.
