Reinstatement of pier 3 vertical position and seismic retrofitting
The project has been developed in three phases. The first emergency phase focused on span 3 and 4 lifting and on pier 3 pushing in order to bring it back to its design position; a second phase – fully achieved – concerned the construction of a brand new footing (foundation) for pier 3; the third phase -in progress- involves the pier 3 jacketing, the shoulders reinforcement, the construction (installation) of a kinematic chain, the implementation of hydraulic seismic dumpers and the full rethinking of the vertical restraint system.
