Development of the region took place largely in the East-West direction (between Gombak and Port Klang) but the urban areas surrounding Kuala Lumpur have since grown north and south towards the border with Perak and Negeri Sembilan respectively.
There is no official designation of the boundaries that make up the Klang Valley but it is often assumed to comprise the following areas and their corresponding local authorities: Even though the Klang Valley officially consists of separate cities and suburbs, integration between these cities is very high, with a highly developed road network and an expanding integrated rail transit system.
However, this has led to the Klang Valley's notorious traffic jams which span whole kilometres of expressways and make driving during peak hours exhausting.
In 2024, National Defence University of Malaysia associate professor Wu Chai Bin believed that the traffic jams in Klang Valley would be relieved in 10 years by improving the public transportation network.
