In the overall result from what was there to now, it seems more of a thoughtful gesture. Residents have endured much louder track noise on the existing steel structure and constant track switch clatter. I speak from experience. Ultimately, the sound walls will reduce certain noise, but to a limit. But imagine showing plans with no visible sound mitigation techniques. The problem with concrete, is unless there’s very specific acoustical treatments, it can bounce sound all around instead of absorbing it. The curve on the flyover is gentle enough that you don’t get that squealing wheel noise, but you’d hear sounds at the rail joints, and there’s a knocking noise, where the train “shudders” at the very top before descending. So it’s best to do all that you can to dampen that.
