A bridge on the Italian island of Sardinia collapsed this Wednesday without causing casualties due to intense rains that were recorded throughout the day in this area of the Mediterranean. The storm of the last hours caused that several localities were isolated. Civil Protection has decreed a red alert for bad weather on the island. The affected viaduct crossed the Santa Lucia river in Cagliari, the capital of Sardinia. The heavy rains suffered throughout this Wednesday have caused flooding in the area and the overflow of the river in some of its sections. The local authorities have decreed the closing of the schools until Friday. The firefighters have had to rescue in the last hours dozens of people who had been trapped in their homes. Some of them waited on the roofs of their homes for the arrival of rescue teams. It is not the first time that the inhabitants of this Mediterranean island suffer the scourges of bad weather. Just ten years ago, Sardinia was the scene of a tragic flood that resulted in the death of four people. On this occasion, the warning due to bad weather prevented victims from being registered as it allowed the local authorities to close traffic to the area as a precaution a few hours before the collapse. According to local media, the bridge, on which a state highway passes, presented some previous collapses of lesser degree. The intense rains that are taking place in Italy are also affecting other areas of the north of the country such as the Piedmont and Liguria regions. The latter, whose capital is Genoa, is on red alert. It is the same city where a section of the Morandi bridge collapsed two months ago, causing 43 deaths. The causes of the tragic collapse are still being investigated.
