Why Egypt Is Building a New Capital City

I really enjoyed this video and would like to answer the most commonly asked questions in the comments,

1- Regarding the transportation to/from and within the new Administrative Capital:
Egypt is extending the highways and roads within the old Cairo and around it through establishing and upgrading the current road infrastructure.
Egypt is also extending the Cairo Metro project to connect the western side of the Nile to the eastern side, and eventually linking the Metro to the biggest station connecting all railways: The Central Station "Adly Mansour" containing a subway station, an electrified train station, and a shuttle bus station to connect the Adly Mansour Central Station with the Cairo International Airport through a direct one trip.
The Adly Mansour station also is the connecting station for the currently in-progress LRT (Light Rail Train). The LRT connects as far as the 6th of October City in the west, to the new Administrative Capital, and all the way to Ain Sokhna city on the western shore of the Red Sea's Gulf of Suez. The LRT would probably expand to reach the new Alamein city on the Mediterranean Sea western of Alexandria.
In addition to all the projects established/under construction in the area of Giza, Alexandria, Cairo, New Cairo and the New Capital, the highways connecting all the governorates and cities in Egypt have been/are being upgraded in addition to a major overhaul of the railway lines and trains.

2- Regarding the no. 1 problem: Water poverty:
Egypt is considering all the diplomatic solutions to solve any conflict around the construction of the GERD in Ethiopia.
Moreover, Egypt is establishing a huge number of water treatment plants to repurpose agricultural and industrial waste for desert reclamation as "Bahr Al-Baqar Water Reclamation Plant"  located on the western bank of the Suez Canal. It is considered the largest wastewater treatment plant in the world (The facility is composed of three plants which were garnered three titles from Guinness World Records, and they are the World’s Largest Water Treatment Plant; World’s Largest Sludge Plant; and, World’s Largest Ozone Generator).
Egypt is also expanding in sea water desalination plants in newly established coastal cities especially in Sinai.
In addition to the plans to increase the water resources, many governmental initiatives are on the ground to decrease water waste in homes, agriculture and industry as well.

I tried to be as thorough as possible. All the details and further information regarding these projects and plans are available with a little Google search. I didn't want to put reference links in the comment in order not to be suspicious :D
