Stacy and I are designing a small layout for Brickworld this year and we
want/need to have a bridge in the layout. We’ve been working to design the
layout using banquet tables (so I don’t have to bring my own tables), yet we
still want an open space in the center. The way we have it designed
necessitates us to try and span 40 inches (128 studs) unsupported.
So here’s the question...has anyone built an unsupported truss-style bridge
that’s around a 128 stud unsupported span? I’m thinking if I sandwich the
deck (4x10 and 6x10 plates) between 1x8 bricks (below) and 1x16 Technic bricks
(above) and then use a standard truss structure with Technic bricks and beams,
I stand a chance of being able to support the bridge and the weight of one
train on it. However, I would love to hear some anecdotal evidence that this
works before I hit Bricklink and spend a bunch on plates, bricks, and beams to
complete this behemoth.

This bridge had a main
span of 96 studs, and could have been more if I had more room on the end to
attach the main cables further from the base of the tower. It could also be
doubled in length by building the same from the other end. The only downside is
that it needs a stable footing to attach the main cables - mine were attached to
the module base (MDF).
