Nasr City
Many neighborhoods in Cairo have unplanned buildings, which resulted in an increasing population density in these areas, so neighborhoods such as Heliopolis and Nasr City had congested streets almost daily and at all times. In late 2019, the government decided to tackle this problem by constructing a large number of overpasses inside these neighborhoods in order to remove intersections and u-turns that resulted in congestion, more than 8 overpasses were constructed in Heliopolis, and over 12 overpasses were built in Nasr City, with Mostafa El Nahas Street alone (a major axis in Nasr City) having four of them. These structures did fulfill their intended purpose, which was to eliminate traffic congestion in these areas, but they received criticism due to many reasons, one of which was the removal of many green spaces in Heliopolis, and the danger they posed for pedestrians crossing the streets.
