Previously, after a survey, the authorities determined that span N5 was tilted outwards towards the Red River (with signs of subsidence at pier T6); spans 2, 3, and 4 showed signs of being twisted and tilted in the direction of the Red River's flow, and the expansion joints (connecting spans) were stretched much further than the original design.
