[citar]Sorry, you must have the wrong number http://imagefap.in.net imagefap saggy In March, bridge officials discovered that 32 of the 96 bolts used to attach a pair of seismic devices known as shear keys to the bridge had broken when tightened. Shear keys are one of two types of seismic safety devices on that section of the eastern span. Bearings allow the bridge decks to move slightly in a vertical motion. Shear keys prevent them from moving too much horizontally. [/citar]
