Transporting the Precast Box
Segments to Site
Transporting the super segments to site was a real
challenge. Weighing from about 80 tons per one
typical segment to as high as about 110 tons for a
pier segment ordinary commercial trailer trucks were
not appropriate. Besides, most of the bridges along
the route were not capable of carrying such heavy
loads. And so, the joint venture company made
special long trailers to transport the segments to the
erection site with 64 wheels to transfer the loads to the roads and were on air suspensions. In areas
where there were these short bridges across the
rivers, a bypass was made especially for the segment
trailers.
