>>3638353As long as the measurements are dimensionally consistent, I can turn it into grade, which is what's piqued my interest.
So anyway, by that picture the run of the ramp segments seems to be roughly 30. Let's go with 30. No idea what the height is, but we can sure make some breakpoints.
So the ADA says that for a truss pedestrian bridge (the ADA's website is down and this was the only thing I could find so just bear with me) you can have a maximum grade of 8.33% if you have a pipe handrail or 5% if you don't.
So for 8.33%, this means the rise can, at most, be 2.5 units of your same scale. The 5% has a maximum rise of 1.5. I have included a crappy diagram where I wrote all over your picture. I only have MSPaint, so sorry about the illegible parts.

I don't know what they're called, that's architect business. Anyway, so in the sake of good spirits we can call it a pass if your rise is 2.5 or less.
I mean, you wouldn't design a bridge that Perrine's good friend Rudel would have trouble using, would you? It's quite hard for her to get around on those crutches and Rudel needs to cross bridges too.
