I stopped by the pedestrian bridge near Anderson Road on a bike ride to see how it looked in person. I noticed a letter attached to the fence asking for people to complain about it:
(Sorry about the angles, it was pretty windy)
From what I could tell on the pathway, about three houses have the wall blocking their view of the mountains, and a couple have to look under the bridge to see the mountains.
As for the comment in the letter that the bridge is "higher and larger than originally discussed so emergency vehicles can pass over" sounds like nonsense to me. The height difference for the larger bridge girders wouldn't be significant enough to be noticeable to any regular person. A pathway on a bridge is already about 4 meters wide which is more than enough to handle a vehicle's width, so I doubt they made it wider over the highway. They would only need to widen the corner near the houses for the turning radius of an ambulance (I can't see a fire truck is going up there).
I'm not sure what to make of the comments that make it sound like every change needs to be run by them but you can't please everyone. I have to guess that it's mostly a couple people pretending to speak for many others.
Here's a picture showing the entire bridge:
