In　this　paper,　structural　analysis　and　design　of　a　tensegrity　bridge　with　prestressed　deck　is　introduced.　As　a　matter　of　fact,　cable　pretension　results　in　prestressing　of　the　deck.　Nonlinear　geometric　effects,　key　load　cases,　influence　of　main　cable＇s　rise　and　modal　analysis　of　this　type　of　structure　is　studied　by　finite　element　method.　The　structural　behaviour　of　the　tensegrity　bridge　appears　to　be　suitable　for　a　footbridge,　although　peculiar　with　respect　to　traditional　footbridges.　Some　suggestions　about　structural　design,　material　properties　and　structural　behaviour　are　summarized.
