Damansara–Puchong Expressway

The Damansara–Puchong Expressway begins at the interchange with the Sungai Buloh Highway and Kuala Lumpur Middle Ring Road 2. The Kelana Jaya line, Kajang line and Sri Petaling line runs alongside substantial portions of the expressway. ==History==

The construction of the Damansara–Puchong Expressway was awarded to Lingkaran Trans Kota Holdings Bhd (Litrak). On 23 April 1996, the concession agreement was signed between the Government of Malaysia and Litrak for the privatisation of the improvement, upgrading, design, construction, maintenance, operations and management of Damansara–Puchong Expressway. Construction of the expressway began in September 1996 and completed in December 1998. The work was awarded on a turnkey basis (i.e. design and construct) to Gamuda–Irama Duta Joint Venture (GIDJV) at a cost of RM 1.1 billion. The overall cost for expressway is RM 1.4 billion. The expressway was opened to traffic on 25 January 1999. With the completion of the Damansara–Puchong Expressway, the Kuala Lumpur Middle Ring Road 2 was substantially completed on the west of Kuala Lumpur which provides for free flow and ease congestion. It also links Bandar Sunway to Puchong and traveling time is shortened between Petaling Jaya and Puchong. The expressways connects the Putrajaya and Hicom/Shah Alam with the Middle Ring Road. The expressway used to have its own electronic toll collection system known as the "FasTrak". From 1 July 2004, the FasTrak was replaced by the Touch 'n Go and SmartTAG systems. Original routes The construction of the Damansara–Puchong Expressway includes the acquisition and upgrades of several major roads as follows:- ==Developments==

Puchong Jaya interchange The upgrading works of the Puchong Jaya interchange including ramp from Bukit Jalil Highway to the expressway began in 2002 and was completed in 2005. Kelana Jaya and Kampung Baru Puchong interchanges The Kelana Jaya interchange which used to be a U-turn junction was completed in 2007. The Kampung Baru Puchong interchange was upgraded from underpass to diamond interchange was completed in 2007. TTDI interchange The TTDI interchange upgrading project is being undertaken by Lingkaran Trans Kota Holdings Bhd (Litrak) to improve the level of service on LDP. The project which commenced in August 2007 with a total budget of RM133 million involves widening of certain stretches and building a flyover and an underpass at TTDI Interchange. The congestion at the interchange is mainly due to multiple weaving of traffic from TTDI to Bandar Utama, TTDI to Damansara Utama and Damansara Utama to TTDI. Once completed, the upgraded interchange will ease traffic flow from TTDI to Bandar Utama/Kepong and there will also be smoother flow on the LDP mainline to Bandar Utama and Kepong. The upgraded interchange will also allow more green time for localized traffic movement. The project work involved the following: • Upgrading of existing TTDI Interchange into a fully grade-separated Interchange through the construction of a new 2-lane bridge flyover for northbound traffic towards Kepong • Localised widening of northbound and southbound slip roads • An underpass from TTDI to Bandar Utama and Kepong. The project was scheduled for full completion in May 2011 with the flyover expected to be opened earlier upon its completion. ==Features==

• A notable feature of the expressway is the LDP Cable-Stayed Bridge on the Freescale Interchange, the first cable-stayed land bridge in Malaysia. • The elevated Sungai Buloh–Kajang MRT line from Mutiara Damansara to Taman Tun Dr Ismail ==Notable incidents==

• 1 August 2013 – Chua Boon Huat, Malaysia's national hockey player died in a car accident on Damansara–Puchong Expressway near Kelana Jaya LRT station at Kelana Jaya. ==Tolls==

There are in total 4 toll booths along Damansara–Puchong Expressway (namely the Penchala, PJS, Puchong West and Puchong South Toll Plazas), all of which are adopting opened toll systems. Electronic Toll Collections (ETC) As part of an initiative to facilitate faster transactions, all toll transactions at four toll plazas on the Damansara–Puchong Expressway have been conducted electronically via Touch 'n Go cards or SmartTAGs since 9 November 2016. Some of the booths were upgraded with RFID infrastructure in 2020 that provides convenience to users who has already installed a RFID tag on the vehicle front and also completed a linking procedure in their smart phone's TnG eWallet app. In March 2023, most of the booths with Touch 'n Go option has been upgraded with a sensor to accept payment by credit card/debit card (Visa and Mastercard), a feat that was not common among established highways (Some highway only upgrades 1 or 2 lanes with the bank card option, like SILK Highway). Similar to the payment using a TnG card, user only needs to place the bank card with sufficient account balance near the scanner at the toll booth for few seconds before the toll fare is debited on the card (the LED display would display "Terima Kasih!" instead of the account balance, similar to RFID payment.)
