I'm pretty sure this is required, yes. This is how Environmental Impact is supposed to work - you identify impacts like increased noise pollution, and propose design solutions like a sound wall.
It looks like they tried to do too much, though. To keep the flyover structure as slender and sleek as possible, they specified a concealed panel connection that looks really nice and clean in a section drawing, but isn't rigid enough. Looks like the concrete spalling is caused by flex in the connection.
