The Kajang–Seremban Highway, KASEH Kajang–Seremban Highway (Malay: Lebuhraya Kajang–Seremban), or LEKAS Highway, is an expressway in Malaysia connecting Kajang, Selangor to Seremban, Negeri Sembilan. The speed limits on the expressway are 80 km/h (50 mph) for the Kajang Perdana–Kajang South and Setul–Paroi sections, and 110 km/h (68 mph) for all other sections.

## Overview

The expressway has a total length of 44.3 km (27.5 mi), passing through Semenyih, Pajam, Mantin, Temiang and connecting to the Seremban Inner Ring Road. It serves as a form of traffic dispersal for other highly congested expressways, such as North–South Expressway Southern Route and the Kuala Lumpur–Seremban Expressway.
The highway project has achieved several stages of completion:
* "Package 1A" (from the SILK Interchange to Kajang South): completed and open to the public.
* "In Package 1B" (from the Kajang Selatan Interchange to Pajam Interchange): earthworks and major drainage have been completed.
* "Packages 2A and 3" (from Pajam Interchange to Paroi): all land acquisitions have been completed. Part of the alignment between Mantin Interchange and Setul Interchange has been approved for realignment.

## Route background

The Kilometre Zero of the expressway starts right after the Exit 1804 of Kajang Perdana Interchange, which connects the expressway with Kajang Dispersal Link Expressway (E18) and the Kajang Bypass near Kajang, Selangor.

## History

The project was approved by the government in 1997 and, the construction of the expressway began in 2002. The construction was delayed, however, due to financial problems faced by the original concessionaire, Kajang–Seremban Highway Sdn. Bhd. (Kaseh). Works resumed in November 2006 with a new concessionnaire: Lebuhraya Kajang-Seremban Sdn. Bhd. (Lekas), with 50% of the stakes held by IJM Corporation Berhad and the other half held by the original concessionnaire. It was scheduled for completion by December 2009.
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. In order to allow users to familiarize themselves with it, the expressway was operated toll-free for a month.
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 was toll-free until 30 January 2009.
On 1 March 2010, the Setul and Ampangan Interchange was opened for traffic.

## Notable events
### Pajam Incident

On 27 September 2007, at around 11:45 pm, eight massive I-20 beams (each weighing close to 70 tonnes) collapsed at BR 7 (approximately Ch.16,400), just about a kilometre from the Pajam Interchange. There were no casualties recorded. In the three months following the incident, the contractor constructed a 4 km. public by-pass road circumnavigating the BR 7 launch site, 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 re-launched them. There were no public funds involved in the repair work, and all costs were borne by the contractor. The BR 7 is now in service and is part of the LEKAS Highway.

### Other events

* 17 April 2010 – Achik Spin (real name Abdillah Murad Md Shari), singer of the Malaysian rock band Spin, died in a car accident on the Kajang–Seremban Highway near Pajam, Negeri Sembilan.
* 3 May 2020 – At around 2:11 am, Koperal Safwan Muhammad Ismail, aged 31, died when he crashed into an OP COVID-19 roadblock near the Kajang Selatan toll plaza.

## Toll systems

As part of an initiative to facilitate faster transactions at all toll plazas, all toll transactions on the Kajang–Seremban Highway have been conducted electronically via Touch 'n Go cards or SmartTAG since 2 March 2016. This is the first closed toll expressway to phase out the closed toll system.
