One of Roebling’s greatest implementations in the Niagara Falls Bridge was his lattice truss design. Unlike the standard lattice truss systems where the diagonal beams lie over each other, his system interlaced the diagonal beams. This provided the structure with a higher rigidity than what was previously possible using traditional methods. This design was not flawless, however, as it substantially reduced the effectiveness of the diagonals. Roebling thought this compromise was acceptable given that the bridge supports served to buttress the system. Another advantage of the diagonal iron bands is that it avoids wooden joints which are comparatively movable and reduce the resistance of the system. A horizontal giving way (buckling) of the truss level is not possible since at the final point the vertical poles take only pulling tension…

This type of truss is similar to the Warren truss but the difference is that the structure is below the roadway. So it requires a few amounts of materials, is light weight, easy to build, usually build offsite therefore quick to build, better more open view o n top and is also economical. The top part of the truss is in compression were as the bottom part is in tension. The interior members alternate between tension and compression to keep a stable structure. This type was first built after the design of deck bridges around 1800.…
