ABSTRACT
A concrete bridge has been constructed on 1979 at Mosul city. The total length of bridge is 660 m and its width is 20 m. The bridge consists of 10.3 m in length for each. Each span was constructed from box girders supported by 9 columns and ceiling by concrete caps. Due to the defects in maintenance along time, the expansion joints experienced severe damage causing horizontal displacement for the upper parts of columns toward the abutments. These displacements create bending moments at the middle parts of these columns. In addition to that, one of girders was deteriorated because of an explosion causing structural failure to this part.
In this work, it is presented a survey for all failures that the bridge experienced. Then after, it was suggested the means that can be applied for rehabilitation the bridge to be enough and stable for sustainable exploitation.
