While under construction the bridge remains largely unaffected by the Kobe earthquake.
The January 17, 1995 Kobe earthquake had its epicenter right between the two towers of the Akashi Straits Bridge. The original planned length was 1990 meters for the main span, but the seismic event moved the towers apart by almost a meter. Since construction of the deck had not yet begun, the change was easily accommodated in the slightly altered final design.
The towers of the bridge contain tuned mass dampers in order to diminish the vibrations in the structure during earthquakes and typhoons.
