They are adding another braces/supporters over on the beams. Why is the bridge being fixed for the whole time of its existence, that's the strange thing...
Wow, that's NOT good news at all. Bridges and flyovers are designed to support several times their rated weights. It's not good at all if they need to add braces to these flyovers...
I do not know how to explain about these things, they look like braces... Or, something reinforced. But they are always fixing something over the cracks on each of the beams, that's the worrying part.
