Finishing the details
Considering the safety of our bridge, we just tested 4 chairs, but after first marking, we will put more chairs to see it’s bearing situations, and redesign.
In the redesign, we strengthened the cables in order to make them stronger. After that, we put one strip of wooden railings on each side. What’s more, two strips of LED lights were put on the bridge, too. The bridge is officially finished
