Using Fibre-Reinforced Polymer for pedestrian bridges isn’t new, is it?<p>A few minutes of googling gives me <a href="https://www.fibercore-europe.com/en/projects/" rel="nofollow">https://www.fibercore-europe.com/en/projects/</a>, which has dozens of FRP bridges. I doubt that’s the only producer in the world. I don’t see what’s special about this one (but feel free to educate me)<p>That leaves the shape. I would guess the corners in the road are there to avoid having to use land that isn’t owned by the railway. If so, what’s left is the specific design. That’s nice, but other nice designs are possible.<p>Now, as to the idea of making a pedestrian bridge over a railway: it’s better than no pedestrian connection, but the stairs on such bridges necessarily are fairly high. Train tracks often lie above ground level, and even if they don’t, the total height to the top of the overhead line, plus some safety, plus the height of the bridge’s deck means you’re easily going two floors up and down.
