Tension is a force on a bridge that pulls, or acts to expand the thing it is acting on.
Tension and Compression
You must be referring to a "truss bridge". A truss bridge is a bridge that has straight connectors. These connectors are stressed from 2 kinds of stressors; tension and compression. It is one of the oldest and simplest bridges.

NOcable stayed bridge is more preferred because if one rope is broken in it then tension is distributed in all other and we get time to repair it that means no sudden failure in it where as in suspension bridge if main cable is cut than it will be destroyed immediately.regardsmukulmukul_ce@student.iitd.ac.in
Well, honey, let me tell you - the Pratt truss bridge may be strong and reliable, but it ain't perfect. One disadvantage is that it requires more materials than some other bridge designs, which can drive up costs. Plus, those diagonal members can be a pain to maintain and inspect. But hey, no bridge is flawless, am I right?
