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 last year 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.
