As an old Structural Engineer I was convinced that it had to be from below to lift those decks, no deck level blast would or should lift those deck spans......until I saw those underneath photo's!
No wonder they managed to build this in just 4 years looking at that design.......never seen a bridge deck span design done like that..! Its certainly, err......different.....you wouldn't see a design like that in the western world. Maybe it was the truck, and the spans did just lift off sideways in the blast!!
if you look at my links in my post earlier they criticised the build as its on a earthquake plain and has a poor bed to put the foundations on.
Question :
Having dropped one lane, the other lane is now putting all the weight on one side of the pier, will that cause issues as the spans are far out from the central pier.
