By enlarging the bridge’s main span from 1,200 ft to 2,230 ft (700 m), the primary support pillars will be situated in very shallow water (a depth of approximately 23 ft), well away from the navigation channel used by large vessels.
“This approach aims to ensure that accidents such as the one that occurred last March, causing the former bridge to collapse, will not happen again,” say CRA.
The design also increases clearance from 185 ft to 230 ft (70 m), in accordance with the shipping industry’s latest standards and enables the Port of Baltimore to remain a major international harbour in the years to come.
The concept also proposes a larger roadway, with a new lane added in each direction, to accommodate increased vehicle capacity, addressing the high traffic levels across the bridge.
The project is designed in collaboration with renowned French consulting engineer and designer Michel Virlogeux, who designed several of the world’s most significant cable-stayed bridges, including Lisbon’s Ponto Vasco da Gama and the tallest bridge on Earth, the Millau Viaduct in the Occitania region of France.
The Baltimore design has been developed for the international construction group Webuild, whose Italian branch was responsible for the reconstruction, carried out in record time, of the Ponte Morandi in Genoa, Italy, which collapsed in August 2018 following severe weather.
