Damansara-Puchong Highway (LDP)
Malaysia (1996 - 1999)
The Damansara-Puchong Higway (LDP) is today one of the nation’s busiest and most travelled urban highway. Located in a highly strategic intra-urban route between Damansara and Puchong, the highway is of tremendous economic significance and proved to be a catalyst for the commercial, residential and property growth of new township developments in Petaling Jaya, Kepong, Sunway and Puchong in the late 1990s.
Originally a double-decker bridge, Gamuda’s ingenuity helped transform the 40km three-lane dual carriageway into an iconic cable-stayed bridge, the most architecturally advanced carriageway of its time. The cable-stayed bridge, a three-level overpass, spans 600m over the Federal Highway Interchange.
A major challenge posed during the construction of LDP was the colossal amount of earthworks involved to fill up the old mining ponds in Sunway that ran to a depth of up to 40m at its deepest end. The process required geotechnical professionals and expertise to compact fill materials in multiple layers and carefully dewater the ponds to ensure the long-term integrity of the highway.
Even so, Gamuda took up the challenge and transferred three million cubic metres of fill to bridge the vast divide between the townships of Sunway and Puchong.
The current Petaling Jaya South toll plaza and the LDP supervision building adjacent to it was built on reclaimed land. Built during “live traffic” across the Federal Highway and requiring major utilities relocation, LDP has 21 bridges, 15 pedestrian bridges, five vehicular underpasses and a state-of-the-art traffic control and surveillance system. It continues to be upgraded till today to accommodate heavy traffic use especially during peak hours.
Interweaved with the Shah Alam Expressway, SPRINT and the North-South Highway, LDP is the single most crucial highway that brings the Klang Valley closer to road users. It also connects the Damansara, Sunway and Puchong locales to Kuala Lumpur via the Middle Ring Road II.
The steep learning curve gained from completing LDP further cemented Gamuda’s construction management capabilities in mega Build-Operate-Transfer concession projects.
