E21: Kajang-Seremban Expressway
Kajang-Seremban Expressway is an expressway connecting
Kajang, Selangor to
Seremban, Negeri Sembilan. It is also known as
Lebuhraya Kajang-Seremban, and by its acronymn
LEKAS. The expressway carries the code E21. It offers an alternative to the North-South Expressway Southern Route and the Kuala Lumpur-Seremban Expressway.
Construction of the Kajang-Seremban Expressway began in 2002, but the project was stalled after the project concessionnaire faced difficulties in completing the expressway. A new concessionnaire took over the project in 2006, enabling the first phase of the expressway to be completed and opened to the public on 23 August, 2008, and the second phase opened to traffic on 1 March, 2010. Since 2 March, 2016, the Kajang-Seremban Expressway accepts only cashless toll payment using Touch 'n Go cards and SmartTAGs.
