The attachment shows a pedestrian suspension bridge built in a resort area in Central America. The span is about 90 meters. The main cable (on either) side is composed of three cables of about 1 inch in diameter. Would the participants in this forum provide technical references with guide lines for design and construction of this kind of bridge. I will appreciate information. Also, do you notice the two small wires bracing the columns of the tower? It seems they were needed during construction, but do they serve any purpose after completion of the structure? Will appreciate your insight.
