摘要：
A floating modular bridge has a plurality of modules of two types. Most modules are flexible fabric envelopes having a parallelogram profile that attains shape and strength when filled on site with a rigid foam that is injected into the envelope. The other module is a keystone that has a trapazoidal profile. These modules are strung together by cables to make a lightweight bridge.
