Seismic Dampening Bridge
The suspension bridge is located in Izmit Bay - a very highly
seismically hazardous area . Therefore, all approaching vi-
aducts will be isolated against a possible earthquake using
4,376 seismic rubber bearings that will be installed on top
of the viaducts.
All 4376 bearings have been supplied by the Turkish
specialists contractors, EM-KE Construction Ltd. by using
Dynamic Isolation Systems (USA) and Robinson Seismic
