Mister Rusty
Stimpy, 
Thanks for the comments.
That bridge was an interesting exercise in perspective modelling.

The parapet is built as a wedge, tapering from left to right by 3mm on left, 4mm on right.

From the edge, note the road camber, this visually throws the left parapet further away, combined with a lower parapet and unequal pillar spacing,  all adding up to fool the eye.
As a further perspective tweak,

The front vehicle (well-known and easily recognisable to many people) is a mini pick-up in 1/72 scale (not 1/76) and the other is a 1/87 Honda Civic, normally bigger than the mini, so again distorts the anticipated image. 
The distance between the 2 vehicles is no more than the length of the pick-up, but from most angles looks more.

I hope that this helps to explain how it was done.
It was done by eye, no measured parts were used, other than spacing the upright plate joints.

Thanks for asking

Anal  ysing how l achieved it, l guess that l took one  visual line to be true, and tapered everything else.
The best line to choose was one closest to the subject matter (trains), and this is the underside of the road deck. 
So it was from there that l started.
Putting in the bend again broke up the focal point, of which none should be strong.

I think Ã°Å¸â„¢â€ž
