International trends towards historical metallic bridges are growingly shifted towards rehabilitation process and dynamic testing including full scale dynamic test that go beyond the maintenance of their structural stability, to include promotion of their historic and engineering significance without taking the decision of rebuilt or demolish . As a major player in world's policies during the 20th century, Egypt possesses a significant legacy of historic metallic bridges across the Nile, mostly built by internationally renowned engineers and major international firms in metallic bridges constructions and directed to rehabilitation and regularly maintenance. Through this research, the present work highlights the significant asset of dynamic testing of metallic bridges taking Al Qanater Rail Way Bridge as a cases history through conducting full scale dynamic test using Ambient Vibration Test (AVT) of the second span of Al Qanater Bridge with and without train dynamic loads and initial numerical modelling for this case using ANSYS 3D. The study assesses current Egyptian rehabilitation methods in the Egyptian code in the light of selected international parameters. Assessment is conducted to detect current shortcomings in historic metallic bridges local rehabilitation and maintenance methods in Egypt, and hence propose a framework for enhancement and implementation for these types of bridge.
