Hello friends,
the devil is just as always in the details.
Just when I wanted to start with the tiny supports for the gutters,
I have noticed that I have to correct the dimensions once more, because I noticed a thing only now, which I have so far overlooked.
The gutters have indeed the same diameter (10'') over the side length of the MLPs, but their height in the first and last bay strangely diminishes outwards as you can see in this image, if one knows it, otherwise it is not striking.
But on the linked HiRes image one can see it more clearly, if one follows the alignments of the gutter.

In the
Bay 18 I then took measurements, and as you can see, the height difference is about 0.5 mm, which is not much, but at least.

And then still to the gutter supports, which are fixed on the girders, as can be seen in this picture.

Merely the outer supports at the sides end differ in shape as one can see in these images, at which the lower flange is missing.

Therewith everything should be clear now for scratching the gutters.
