Structures That Are Bridging Places & People
From road bridges to rail bridges and marine bridges, Gamuda has constructed engineering marvels all over Malaysia and across the international shores.
We take pride in building modern bridges that are functional, architecturally majestic and able to withstand harsh weather fluctuations.
Here is the story behind our bridges, showcasing our expertise and the challenges we overcame by flexing serious engineering muscle.
Lebuhraya Damansara-Puchong Cable-Stayed Bridge
From mining pond to overpass, Lebuhraya Damansara-Puchong (LDP) has gone down in history as one of our most extraordinary feats of engineering. We decided to build not a two but a three-level overpass and placed the notable LDP Cable-Stayed Bridge at the topmost level.
The belle of bridges in its heyday, we opted for its celebrated cable-stayed bridge design for a practical reason – it is also aesthetically pleasing, which is a bonus!
As the bridge and highway were to be constructed at a very busy intersection of an industrial park, we had to find ways to minimise disruption to the local traffic below. A cable-stayed concept can be built with a central span of about 200 metres, so it does not have to have columns at the bottom, interfering with traffic.
Simultaneously, we engaged with the authorities to implement an efficient traffic management plan. Thanks to the excellent planning and execution by our engineers, we came, we saw, we constructed.
Prai Swing Bridge & Bukit Merah Marine Viaduct
A legend like the Prai Swing Bridge must be preserved. That’s what we did when we reconstructed this monument as part of our larger Ipoh-Padang Besar Electrified Double Track Project. We maintained its appearance and iconic blue!
Movable bridge systems are among the most remarkable in bridge construction. This unique bridge swings horizontally, opening at a 72° angle, accommodating vessels to cross the Prai River. Its central pivot design optimises electric trains that move at speeds between 140 to 160 kph and requires no counterweights as well as high piers, resulting in significant cost savings for construction and maintenance. The bridge utilises electro-hydraulics system with independent underwater power and backup generators for reliable operation.
The major concern when constructing the Bukit Merah Marine Viaduct running across the lake was pollution to the reservoir. Thus, we anchored a silt curtain tightly to the lakebed to stop debris from contaminating the water treatment plant, which we can proudly say remained fully operational throughout the construction period.

Batang Lupar Bridge No. 2
With towers at 145.5m high and a navigational clearance of 23m, this bridge’s record-breaking height demands meticulous construction methodology and monitoring. Extensive design cross-checking and sophisticated stage-by-stage load analysis are carried out using the MIDAS software, ensuring the structural integrity of the towers and deck.
Key construction measures include riverbank stabilisation, a temporary cofferdam for the pile cap, steel supports for the tapering tower legs, and an underslung form traveller for balance cantilever bridge deck construction. We also adopted drone surveying and digital mapping to carry out the as-built survey and quantity calculation.
To date, the progress stands at 45%, and we’re on track to meet the target completion date.
Sitra Causeway Bridges
Gamuda upgraded the more than 30-year-old bridges and causeway between Bahrain’s capital, Manama, and the nearby Nabih Saleh and Sitra Islands.
Exposed to highly saline water, salt spray and salt-laden dust, fluctuating temperatures, and high humidity, the Arabian Gulf’s harsh marine conditions posed big challenges to the project.
We used stainless steel rebars, which offer greater durability and longevity. Additionally, chloride-resistant concrete mixes were used to reduce corrosion of steel reinforcement. We also carefully navigated buried utilities during the project.
The new four-lane dual-carriageway system is designed with a lifespan of up to 120 years in tough environments.
Kuantan Bridge
One of the most iconic bridges on the east coast today, the four-lane Kuantan Bridge caters to road vehicles, as well as marine vessels underneath.
When it comes to building this type of marine bridge, its height must be properly calculated to provide sufficient vertical clearance. Flooding and erosion are common risks associated with bridge construction over a river. Geotechnical issues could also cause instability, settlement, or soil liquefaction.
It requires thorough site investigation, reviewing the project scope and specifications, and consulting with stakeholders and experts. We also reinforced the bridge to withstand ship impacts and collisions.
Did you know that in the Kuantan River also has dozens of crocodiles, according to the State Wildlife and National Parks Department?
Guantang Marine Bridge
Guantang Marine Bridge connects a Liquefied Natural Gas Receiving Terminal to a man-made island and road embankment.
We hired a dedicated risk management team with maritime meteorology knowledge to schedule work around wind, wave, tide and current forecasts to minimise risks.
To enable our workers to work in dry conditions and away from waves, we used steel box cofferdam for pile cap construction.
We also used precast segmental girder boxes instead of in-situ casting to reduce offshore lifting and concreting work and the need to work at height.
We’re proud to share that this project has been singled out for its rigorous engineering and safety measures to mitigate weather-related risks to marine construction workers. We are the first Malaysian company to win the Public Construction Golden Safety Award from Taiwan’s Ministry of Labour.
