 New royally-sponsored buildings continued to be built even in the 19th century under Muhammad Ali Pasha and his successors.In the 20th century, the construction of a major bypass road known as al-Azhar street, running from modern downtown Cairo in the west to al-Azhar and then later to the Salah Salem highway in the east, created a major interruption in the traditional path of al-Muizz street.Today, the old city is, to some extent, split into two by this major road cutting across the former urban fabric, passing between the Khan al-Khalili area and the 16th-century Sultan al-Ghuri complex.
