One of the most important components in the currently largest infrastructure project of Portugal is the new 930 m long Rio Ceira Bridge, crossing the Ceira River near Coimbra at its highest point 140 m above the river bed. Since during construction the vertical plane curvature of the bridge had to be balanced, assymetric loads were counteracted by DYWIDAG Post‐Tensioning Tendons that were anchored in the pier foundations and connected to the top of the bridge deck. As soon as the individual segments of the box girder deck had been connected, these temporary tendons were removed. 1,450 t of prestressing steel were used for this purpose. ( © DSI, see p. A5 )
