The statement added that the accident did not cause any injuries or damages.
Traffic in the El-Agouza and Mohandsein districts came to a screeching halt after one of two sections of a pedestrian bridge shifted and fell from the supporting concrete pillars onto the vehicle that collided with the bridge.
Investigations revealed that there was no mechanical malfunction in the truck, which had been carrying asphalt, but that the driver, having unloaded the truck beforehand, left the flap open.
While the vehicle was passing below the bridge, the flap collided with it.
Ahmed Rashed, Governor of Giza, said the Giza Security Sector and the General Administration of Giza Traffic were dispatched to redirect traffic until the road was reopened.
According to the statement, several necessary equipment and cranes were also deployed to raise the bridge.
Rashed also issued directions to suspend height limiters so that vehicle drivers can determine the permissible heights for crossing under pedestrian bridges to ensure the citizens' safety.
