Eight people died and 10 were injured in the late hours of Friday when a truck fell off the Ring Road Bridge in Moneib and crashed onto a microbus stop underneath.
The truck was laden with rocks used in construction and caused damage to at least two microbuses.
Prosecution’s initial investigations revealed that a car cut off the truck, which led to the truck driver losing control and crashing with a microbus parked near the crash barrier of the bridge and careering off the bridge.
Egypt’s prosecution ordered the arrest of the truck driver who survived the accident.
Giza Governor Mohamed Kamal El-Daly said compensation would be given to the families of the deceased as well as the injured.
The microbus was parked to take in more passengers.
Authorities have been working on clearing the scene of the accident.
Egypt is notorious for its poor road safety, badly maintained infrastructure, and loosely enforced traffic regulations.
Last month, the country's census authority said that over 2,800 people were killed in road and train crashes in Egypt in the first half of 2015.
