GENOA, ITALY- Once one of the darlings of the city’s architectural landscape, Genoa is looking at seeing a new bridge being built soon. The Morandi Viaduct had spanned the valley with railways, streets and a small river going through the city, carrying the Autoroute 10 and E80 for 51 years until the tragedy of 14 August, 2018. There, one of the three towers of the concrete cable-stayed suepension bridge- which was a gap of 210 meters out of the total length of 1,180 meters- gave way during a severe storm, killing 43 people.

Two weeks after the collapse, plans are in the making to tear down the entire structure and replace it with a brand new one. According to information from multiple sources, the Five-Star Government will oversee the construction of a new bridge, to be built at the cost of the previous owner of the Morandi Bridge, the Autostrada Company, which had owned the cable-stayed suspension bridge for over a decade. The cost for rebuilding the bridge is unknown but it is estimated to be in the billions including the cost for removing the old structure.  The reason for the plan is, according to transportation minister Danilo Toninelli, the company owning the bridge had neglected the structure by ignoring the problems involving the concrete stayed cables and the roadway and by financing for the new bridge it would be the best possible way to compensate for the loss of people involved.

The bridge was built by Ricardo Morandi, who was known to have built several concrete cable-stayed suspension bridges during his days as a bridge engineer. One of them, the General Rafael Urdaneta Bridge in Venezuela that was built in 1964, is the longest bridge of his type in the world. The collapse of the bridge in Genoa. Like the bridge disasters in Minneapolis in 2007 and Seattle in 2015, the collapse of the Genoa Bridge is producing backlash as countries are scrutinizing his works carefully because of concerns involving the concrete cables that are supposed to hold the bridge in place, but failed in Genoa. Yet, like in the two previous disasters, despite all attempts to present the problems involving the bridge in the past decade, they were ignored until it was too late. The problems were ranged from a lack of maintenance to the lack of adaptation to the increase in the volume and weight of traffic in general.  The question is whether Italy will repeat the same mistake made by the US Government in trying to condem certain bridge types but failing due to the high numbers built and rehabbed combined with costs for replacing them. This is Italy’s third bridge failure this year, regardless of bridge type, and its 11th in five years.

The engineer behind the design and construction of Genoa’s replacement is a world-renowned architect Renzo Piano. For almost 50 years, the 81-year old Italian architect, who originates from Genoa, has built several masterpieces, including the Pompidou Centre in Paris, the Paul Klee Center in Berne, the Shard Tower in London and was the master planner of Potsdamer Platz in Berlin. He designed two bridges- one in Chicago and another in Amasuka, Japan. The Genoa Bridge project will be his fourth for his hometown and his third official for the bridge. How he bridge wil be designed and built remains in the air has the plans have been presented by the government. The Chronicles will keep you up to date on the latest stories there.
