The bridge comprises a 70-metre high pylon, 24 steel cables and a circular bridge deck and is made out of circa 1.000 tons of steel. The cables are attached to the inner side of the bridge deck, right where the bridge deck connects to the circular, concrete counter weight. This way, torsion within the 72-metre diameter bridge deck is prevented.
To ensure stability, concrete was added to sections of the bridge deck as well. The M-shaped supports near the approach spans also ensure stability.
Soon after the pylon was put in place, the cables started vibrating visibly. Vibrations like these (caused by the wind) are nearly impossible to predict. After extensive research by structural experts, two types of dampers (high frequency and low frequency) were attached to the cables, solving the vibration issues.
