KOBE--Akashi Kaikyo Ohashi is one of the world’s largest suspension bridges and now a tour takes visitors to the top of one of the 300-meter-high main towers that support the massive structure.

Aesthetic, light, and strong, suspension bridges can span distances from 2,000 to 7,000 feet—far longer than any other kind of bridge. They also tend to be the most expensive to build.
