What happens when an earthquake moves a bridge’s foundations before its road deck is finished? At Japan’s Akashi Kaikyo Bridge, construction measurements and remaining deck components had to be revised.
The nominal main span increased by about 3.3 feet (1 meter). This illustrates a change during construction, not a finished bridge simply stretching by a meter.

ABOUT THE ILLUSTRATION
Construction-stage schematic, with cables but no completed deck. Ground, footing and tower move together; displacement and timing enlarged. Final nominal main span increased from 1,990 to 1,991 m, about 3.3 ft / 1 m, not the exact measured displacement of every foundation. Remaining girder dimensions were revised. This does not depict a finished bridge elastically stretching by one meter.
