Name of the Project
Polcevera river bridge.

Location
Genoa, Italy.

Project Owner/s
Autostrade.

Project Description
The bridge over the Polcevera connects the Port of Genoa and the wider coastal area to France. The bridge collapsed in August 2017.

The new bridge will play an important role in Genoa’s returning to being an important shipping and commercial hub. It will have a continuous 1 067-m-long steel deck with 20 spans.

It will have 19 elliptical piers made of reinforced concrete, the majority of which are positioned 50 m from each other. Two of the piers will be 100 m from each other because of their location on the river and the railway.

The design takes into account that the bridge crosses a densely populated area.

Once completed, the bridge will be equipped with technology that will make it a sustainable piece of infrastructure. It will have solar panels to generate the electricity needed to power its lights, sensors and other systems that will help to provide constant monitoring of the structure. There will also be robots to inspect its soundness and conduct regular maintenance.

Potential Job Creation
None stated.

Capital Expenditure
Not stated.

Planned Start/End Date
The project is expected to take 12 months to complete, which will start after the demolition of the old bridge.

Latest Developments
With the setting of the last pier on February 18, workers have increased the pace as they approach the completion of the bridge.

On March 10, 2020, they installed a 100 m section of the deck that stretches above the Polcevera river. This latest milestone, achieved by Salini Impregilo and its joint-venture partner Fincantieri, brings the combined length of the installed sections that will comprise the deck to 650 m, covering 11 of 19 spans that will be part of the completed structure. Work continues at various stations throughout the site contemporaneously.

The installation of the latest section of the deck was done between Piers 9 and 10. At 40 m above the river, the section is 94 m long and weighs 1 800 t.

The operation entailed transporting the section across the river using remote-controlled wheeled platforms that were used to remove demolished pieces of the old Morandi bridge. The platforms carried the section across a bank of earth raised on the riverbed. Once in position, the section was hoisted by strand jacks at 5 m/h until it reached the top of the piers.

Key Contracts and Suppliers
