This is a tremendous feat of vedic injineering.

not Vedic. this is the islamism of RJD, JDU combine.

India suspension bridge collapses for a second time

How to fight against China like that?
[06/06, 13:50] g: Indians administrators and engineers and technicians and all CECA cockroaches from Indian skools. So that kind of collapses very much to be expected

Fantastic engineering by Biharis. 90% gone in bribe to Laloo family.

Normally I'd be the first one to make fun of Biharis. But in this case it is fake news.

This was a planned demolition.

Bridge over Ganga ‘collapses’, Bihar says planned demolition

The construction of the 3.1-kilometre-long bridge connecting Aguani in Khagaria district with Sultanganj in Bhagalpur began in 2014 and was expected to be completed in 2019. The deadline has since been extended four times.

Technical Explanation:

The two towers collapsed in different modes.

The far end tower's column looks like V-shape but are twin vertical columns. The photo shows the far column broken off and the near column pivoted at the base so that the deck rotated anticlockwise with the mid span hit the water. It is noteworthy to point out some but not all cables appeared to snap off. If the collapse was intentional then the explosives would have been placed at different position of the twin columns. If the collapse wasn't intentional then the far column appeared to suffer a tension failure during the deck rotation.

The near tower shows clearly the twin columns folded at the bottom. The deck appears to move horizontally away from the shore. Again two possibilities. Had the collapse been intentional the explosives would have been placed at the same location at the bottom of the columns and none on the cables as none was broken. Once some concrete blasted off the joint became a hinge to effect a controlled collapse. Although the video did not show any explosion at the base of the twin columns. Then again if the collapse wasn't controlled then this tower wasn't stable on its own when the horizontal restraints was removed at the midspan due to the far tower failed first. Normally the tower would have been stable and able to stand on its own but the cables angles are relatively small resulting large horizontal component force (especially when construction loads were unequal on either side of the tower). This cable-stayed geometry is different by having relatively short tower with wider fan than normal.

The way people are close by and running away from the aftermath, it seems the 'plan' was stupid to the level of bridge failure.
