The Kajang–Seremban Highway, commonly referred to as the LEKAS Highway or KASEH (Malay: Lebuhraya Kajang–Seremban), is a key expressway in Malaysia that connects Kajang in Selangor to Seremban in Negeri Sembilan.

Speed limits along the highway vary between specific sections of the route. For example, certain stretches, such as that between Kajang Perdana and Kajang South and that between Setul and Paroi, are restricted to 80 km/h (50 mph), while most other segments of the highway permit a maximum speed of up to 110 km/h (68 mph).

Overview

With a total length of 44.3 km (27.5 mi), the Kajang–Seremban Highway traverses through Semenyih, Pajam, Mantin, and Temiang. The expressway connects to the Seremban Inner Ring Road. It helps redistribute traffic flow from other heavily congested expressways, including the North–South Expressway Southern Route and the Kuala Lumpur–Seremban Expressway.

The highway project has progressed through multiple stages of completion:

• Package 1A: SILK Interchange to Kajang South – completed and opened to the public.
• Package 1B: Kajang South Interchange to Pajam Interchange – earthworks and major drainage completed.
• Packages 2A and 3: Pajam Interchange to Paroi – land acquisitions completed; a segment between Mantin and Setul Interchanges approved for realignment.

Route background

The Kilometer Zero of the expressway starts from Exit 1804 of the Kajang Perdana Interchange, which connects the expressway to the Kajang Dispersal Link Expressway (E18) and the Kajang Bypass near Kajang, Selangor.

History

The LEKAS Highway project was approved by the Malaysian government in 1997. Construction commenced in 2002 but faced delays due to financial challenges encountered by the original concessionaire, Kajang–Seremban Highway Sdn. Bhd. (KASEH). In November 2006, the project resumed under a new concessionaire, Lebuhraya Kajang-Seremban Sdn. Bhd. (LEKAS), a joint venture between IJM Corporation Berhad and KASEH, with 50% stake held by IJM Corporation Berhad and the other half held by the original concessionaire. It was scheduled to be completed by December 2009.^[1]

Phase 1 of the expressway connecting Kajang South to Pajam was officially opened on 23 August 2008. The main subcontractor was WCT, which then subcontracted the beam manufacturing to Mudajaya. To allow users to familiarize themselves with the expressway, it operated toll-free for a month.^[2]

The expressway system was extended with the opening of Mantin toll plaza on 31 December 2008. The main subcontractor was WCT, and the beam manufacturer was Mudajaya. The extended route remained toll-free until 30 January 2009.^[3]

On 1 March 2010, the Setul and Ampangan Interchange opened for traffic.^[4]

Notable events

Pajam incident

On 27 September 2007, at around 11:45 pm, eight large I-20^{[expand acronym]} beams (each weighing close to 70 tons) collapsed at BR 7^{[expand acronym]} (approximately Ch.16,400),^{[expand acronym]} approximately one kilometer from the Pajam Interchange. There were no casualties recorded. In the three months following the incident, the contractor constructed a 4km public bypass road circumnavigating the BR 7 launch site,^{[clarification needed]} from the Federal Route FT3265 to the Pajam Interchange, then onto the Pajam Toll Plaza, and coming out again at FT3265 nearer to the town of Nilai, recast the eight I-20 beams, and then r-launched them. There were no public funds involved in the repair work, and all costs were taken by the contractor The BR 7 is now in service and is part of the LEKAS Highway.
