Becca Bridge

Year: 2010-2017 - Location: Pavia, Italy

Extremely urgent design and retrofit of the ‘900 steel bridge as a consequence of the partial collapse of a pier; 3.400 ft, 13 spans.

The Becca bridge is a steel bridge built in 1912 at the confluence of the Ticino with the Po river. The length of the bridge is 1.040 m, divided into 13 bays. Following a flood of the Po, two piers were heavily damaged, one of them was partially collapsed. In only 30 days, in emergency conditions, and working from the river by means of pontoons, was carried out the provisional reinforcement of the deck, changing its static scheme, and two support structures have been built at the sides of the pier. These structures are made of six 45m long piles, they became fully operational subsequently the collapse of the pier.

Following the reopening of the bridge (with reduced traffic flow) retrofitting works continued for reinforcement of foundations, strengthening and restoration of steel deck.
