This project is expected to cost between RM5-10bn and go on for 20-25 years. The KLLC is lifted gracefully over certain stretches of the Klang River that meanders from the heart of the city to one of the most populous corridor of KL (a distance of 12km from Jalan Tun Razak to Old Klang Rd) and consists of mixed developments (including the 1.8km long Gigaworld - a massive retail-office-hotel-apartment complex) and is integrated by a 15km long elevated People-mover Rapid Transit System (PRT). The PRT is integrated with the LRT1 and LRT2 transit systems [see above] and the massive KL Sentral (map). Both the PRT (with its 22 stations) and Gigaworld are expected to be completed by the year 2000 and is expected to cost RM2.2 billion. The PRT is being built by a Malaysian-Japanese venture called KL PRT Sdn Bhd led by businessman Vincent Tan of multi-industry firm Berjaya Group Bhd. Also included is a 99-yr river cleaning and flood mitigation project plus a 12 km long landscape linear park.
