3 3/4 cars = 3.75x32 Studs (couplings included) = 5 triangles = 120 Studs
That means each triangle is 24 studs long...

the 2.5 are estimated and the 50 studs are in fact more than 60...

Each yellow part is 96 cm as demonstrated above: 5.15 minus 2x0.96 =?3,23 m?
That is impossible. So the 5.15 cannot include both yellow bridges, or the bow
would become very small....

It is in fact 5.15, wich can be recognised if you count the monorail track
pieces: there are 20 sections of monorail: each is 32 studs long. Makes 640
studs total length which is 5.12 meters.

You really bluffed me for a few days. I was not too sure about the real length,
till a friend of mine told about the length of the monorail track pieces (a
part which I never owned).
Kind regards,
Ben

Well, just being picky, but it looks to me like there's only about 19 monorail
sections *between* the footings, but whats 32 studs between friends? 8?)

You are right: there are "only" 19 full sections on the bridge, but of course
there are two times 50% of a section too (easily to see on the left and since
the bridge is symmetric it has to be on the right too).

Makes 20 in total and still 640 studs...

To the *centre* of the footings, yes. But not *between* the footings. I'm
not actually sure where the span of various bridges is measured, but I
thought in such a bridge it would be the distance between nearest
extremities of the footings. Anyone know?
