The Great Seto Bridge connects the main island of Japan, called Honshu, with the fourth biggest island in the archipielago, called Shikoku. Being a little bit over 13 km long, it is the longest two-tiered bridge in the world, a record that belonged during many years to the Golden Gate bridge in San Francisco.

This great picture was taken by Chris Willson at 5:00 a.m from the Honshu side of the bridge right where it begins.
