The 875m-long part of the truss
bridge was constructed using the strand jack
lifting method. The large truss block whose
length was equal to the span length was fabricated
at the shop near the site. The block of theintermediate
support was first separated using a 2000t floating
crane. The rest of the span was shipped on the
10000t barge using a tidal difference. The barge
was pulled into the jetty at low tide and, as
the tide level rose, the span was automatically
shipped on the barge. After shipping, the loaded
barge was tugged out of the jetty and pulled
into the site. At high tide, the barge was pulled
into the space between the piers. As the tide
level fallen, the transported span was placed
on the temporary support that was installed
on the pier foundation. Lifting was performed
after the lifting post was connected to the
truss and the strand jacks were installed. The
lifted large block and the small block were
connected and the placement of the block was
adjusted using the hydraulic jacks placed on
the pier top.
