The distance between each pillar is 400 meters.

The diameter of the cross-sectional circle of each pillar is 5 meters. The height is 100 meters.

The bridge deck is divided into 10 sections according to the distance of the pillars, and each section is about 400 meters long. Each section is named after the pillars as 'Zone 1', 'Zone 2' and so on to 'Zone 10'.
