Damansara-Puchong Expressway

The Damansara–Puchong Expressway or Lebuhraya Damansara-Puchong, LDP, is a major expressway in Klang Valley, Selangor in Malaysia. It links major townships in Damansara and Puchong and decreases travel time between them. Besides that, the 40 km expressway provides better accessibility to these areas via links to other expressways in Klang Valley, such as Federal Highway, Puchong-Sungai Besi Highway , New Pantai Expressway (NPE) , Sprint Expressway , Sungai Buloh Highway , and Kuala Lumpur Middle Ring Road 2 (MRR2). This expressway is part of the Kuala Lumpur Middle Ring Road 2 Scheme.

Pioneer routes
The construction of the Damansara-Puchong Expressway includes the acquisition and upgrades of several major roads as follows:-

Upgrading of the 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.

The Kampung Baru Puchong Interchange was upgraded from underpass to diamond interchange was completed on 2007.

Upgrading of the TTDI Interchange
The TTDI Interchange upgrading project currently being undertaken by Lingkaran Trans Kota Holdings Bhd (Litrak) is an effort 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 involves 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 is 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
