The bridge's central span increased by one meter during the 1995 Kobe earthquake, requiring a redesign of the original deck length.
The combined length of the steel wire used in the bridge cables is long enough to circle the Earth seven times.
The tower foundations were constructed using a pneumatic caisson method in water depths of up to 60 meters.
The bridge is designed to withstand wind speeds of up to 286 kilometers per hour.
The paint system used on the bridge is a two-layer fluororesin coating specifically developed to resist salt air corrosion.
The Akashi Kaikyo Bridge Exhibition Center is dedicated to the engineering and construction history of the world's longest suspension bridge. The facility houses interactive models and VR experiences that illustrate the structural mechanics of the 3,911-meter-long bridge. Exhibits cover the 1995 Great Hanshin Earthquake's impact on construction and the subsequent design adjustments made to the central span. Visitors can learn about the 'stiffening girder' technology and the specialized steel cables used to withstand harsh maritime conditions. The center functions as an educational facility under the oversight of the Honshu-Shikoku Bridge Expressway Company. It provides detailed visualizations of the bridge's wind-tunnel testing and deep-sea foundation anchoring techniques. The building is positioned adjacent to the Maiko Marine Promenade, directly overlooking the Akashi Strait.
The viewing platform terrace facing the bridge towers.
Combine your visit with the Maiko Marine Promenade walkway for a view from beneath the bridge deck.
Check for special guided bridge-top tours, which are organized periodically and require separate registration.
The center is highly technical; focus on the VR stations for the most accessible explanation of complex engineering.
Do not mistake the center for the bridge's main maintenance offices; the exhibit space is specifically for public education.
Closed on Mondays and during the year-end/new-year holiday period.
