Punakha Longest Suspension Bridge is the longest suspension bridge in Bhutan measuring 180 m in length. From the bridge, you can get a spectacular view of the Po Chhu River (male river) and the valley. It's an ideal place for a photo shoot with a stunning background. Cantilever beams were developed in order to cross increasingly wide streams or rivers, where simple wooden beams had a limited range of about 10 meters. Two arms with timber superimposed are. Discover Punakha Dzong and its iconic Bazam cantilever bridge — a powerful story of Bhutanese heritage, resilience, and masterful traditional engineering.
