History
Kajang Dispersal Link Expressway used to be called Jalan Kajang–Puchong (Jalan Sungai Chua on Kajang town side) 11 and Jalan Balakong 3211. The huge traffic jams that clogged traffic flow in Kajang town centre were the main reason behind the construction of the highway. Construction began in 2002. The expressway was completed in 2003 and began operation on 15 June 2004.[citation needed]
Features

Kajang Dispersal Link Expressway is fully lit at night and has 11 multi-level interchanges. The expressway has computerized traffic information display and monitoring system and 24-hour highway patrol. The expressway concessionaire offers emergency and vehicle breakdown assistance.[citation needed]
Tolls
The Kajang Dispersal Link Expressway uses opened toll systems. In October 2022, it was one of the four expressways maintained by PROLINTAS to have its toll rates deducted between 8% and 15%.[1][2]
In almost every plazas, one of the toll booth marked "Touch 'n Go" houses a Touch 'n Go card reload machine on both the directions (except Sungai Balak, which is only available in the Southbound direction), totalling 7 spots which users can reload their card without fee all the time.
Electronic Toll Collections (ETC)
As part of an initiative to facilitate faster transaction at the Sungai Long, Bukit Kajang, Sungai Ramal and Sungai Balak Toll Plazas, all toll transactions at four toll plazas on the Kajang Dispersal Link Expressway have been conducted electronically via Touch 'n Go cards, bank cards with NFC function (VISA & Mastercard), myRFID or SmartTAGs currently.
Self-Service TnG Card Reload Machine
In almost every toll plaza on both directions, one of the toll booth is marked "Tambah Nilai" ("Top Up") in blue color along with "Touch N' Go" logo. In those booths, a self-service Touch 'n Go card reload machine before the scanner location can be found, allowing users to reload their card anytime.
Availability of such facility as of May 2026 is as follow.
