The Cairo-Alexandria Desert Road is a major highway in Egypt, connecting the two largest cities in the country. The road, which is approximately 160 km long, begins in Cairo and ends in Alexandria.

The Cairo-Alexandria Desert Road was constructed in the early 1950s as part of a larger plan to improve Egypt's infrastructure. The road was designed to facilitate trade and travel between the two cities, as well as to provide access to the desert regions of Egypt.

The road is divided into two sections: the Cairo-Joulz section and the Joulz-Alexandria section. The Cairo-Joulz section is approximately 100 km long and passes through the desert regions of Egypt, including the Western Desert and the Fayoum Oasis. This section of the road is the most challenging, as the terrain is often rugged and the temperatures can be extreme.

The Joulz-Alexandria section of the road is approximately 60 km long and passes through the Nile Delta region. This section of the road is less challenging than the Cairo-Joulz section, as the terrain is generally flat and the temperatures are more moderate.

The Cairo-Alexandria Desert Road is an important transportation link for Egypt, as it connects the two largest cities in the country. The road is also an important route for tourism, as it provides access to the desert regions of Egypt, including the Western Desert and the Fayoum Oasis.
