A bridge over the Vitim River in eastern Siberia is certainly one of the scariest and most dangerous crossings on the planet. This 20m (66 feet) high, 500m (1,640 feet) long bridge is barely wide enough to fit a vehicle on it and comes without any safety railing. Despite its below-par condition and old decaying wooden flooring, the bridge is actively used daily by some 1,500 people at their own risk. Drone footage shot in autumn 2016 shows a vehicle making the perilous journey.The bridge was built around 30 years ago but was never officially put into operation.
