It is well known that all projects takes much longer time to complete than it really require. I don't know why.
But usually every thing here takes so long time. Even when processing paperwork.

A single road or a traffic light may take a year till it is reconstructed. A new bridge takes years till it is completed.

I have been working in Cairo for a year and I witnessed a construction of a new bridge for cars and another bridge for a railway metro and a 2 km underground traffic tunnel , all completed in 6 months.

I think Dubai prjects are built in a short time as well.
