Editing Riyadh (section)

==== 1980s–1990s ====
The city grew at a much faster rate than Doxiadis Associates had projected and very soon, their plan became obsolete. DA predicted that Riyadh's urban area would be 304 km<sup>2</sup> in 30 years when it reached 400 km<sup>2</sup> just four years after the plan was authorized.<ref name=":0" /> Therefore, SCET International was assigned to revise and update the original plan to reflect the drastic growth and offer adaptive measures, which were approved in 1982. While keeping the 2km x 2km block, they expanded it in all directions unlike DA's linear expansion. They also added the radial ring roads and altered the DA conception of how commercial and other zones should be distributed.

It was in the 80s and 90s that most of the buildings that defined Riyadh's urban identity were constructed. Built in styles contemporary of that time, marble with a hint of desert beige, these included the [[King Khalid International Airport]], [[King Fahd Stadium]], Television tower, [[King Saud University]] new campus, the King Faisal Foundation, the Ministry of Interior, Ministry of Foreign Affairs, MOMRA, and [[Imam Mohammad Ibn Saud Islamic University|Imam Muhammad Ibn Saud university]]. And the historical district was rebuilt with the National Museum, [[Qasr Al Hukm District|Qasr AlHukm district]], and the [[Imam Turki bin Abdullah Mosque|Imam Turki bin Abdullah mosque]].<ref name=":1" />  Numerous health facilities were founded as well. Other developments in this period included the opening of the first shopping centers and supermarkets.

Approaching the 2000s, Riyadh had expanded well beyond the Northern Ring Road in the north and had reached the Second Ring Road in the east.
