I’ve found the deck can be pretty insubstantial; even in minifig scale, the
truss carries the weight.
The Notre Dame Bridge is about 320 studs long and has been up for over a year
now:
At least, I have heard no news of its collapse. It can take quite a bit of
weight. Many thanks to TJ Avery’s fantastic lbridge design spreadsheet
available at texbrick.com. There are spreadsheets for
both arch and straight trusses.
The “cables” are actually sandwiches of three layers of 1x plate built off the
end of each vertical member of the truss. They tie directly into the business
part of the underside:
The beams supporting the deck consist of sandwiches of three layers of plate,
mostly 2x8. The stacks of 1x3 and 1x4 bricks were included only for show. The
deck floats on top of the support beams. I think it’s a sandwich of two layers
of plate. The deck could easily be replaced with track that would need only a
minimum of reinforcement.
Hope this helps!

| 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 (...) (16 years ago, 22-Jan-08, to lugnet.trains, lugnet.town)
