Noise Barrier
Noise Barrier
This project case covers the installation of metal noise barrier panels along the outer edge of an elevated bridge structure. The barrier runs as a continuous curved line beside the deck, where the elevated alignment passes close to high-rise residential buildings and busy roads.

Elevated bridge structures carry road and rail traffic above ground level, so noise radiates outward and downward towards the buildings and streets alongside the alignment. Where the structure runs close to residential blocks, a barrier is needed along the outer edge of the deck to reduce the traffic noise that reaches nearby homes and pedestrians. The barrier also has to follow the curve of the elevated structure and stand up to wind, vibration and weather over the long term.
Metal noise barrier panels are mounted along the outer face of the elevated bridge structure, forming a continuous screen that follows the curve of the deck. The panels are set into a metal frame and fixed with bolts, so the run can be built in repeating bays and adjusted to suit the alignment. In this project the panels are finished in green and white, giving a clean, even appearance that sits comfortably with the surrounding residential and roadside environment.

Each bay is built from standard metal noise barrier panels, so the barrier is modular and can be assembled panel by panel along the elevated structure. A close-up view shows the panel faces, the fixing frame and the bolted connections that tie the panels together.

Because the barrier is installed along an elevated line, the panels are lifted into position from the ground. A boom lift is used to raise panels and frame components to deck level, where the crew aligns and bolts each section in place.

Once complete, the barrier forms a long, continuous screen along the outer edge of the elevated structure. Seen from the air, the finished run follows the curve of the alignment and stands as a neat, uniform band of panels above the road and the surrounding buildings.

Yes. Because the panels are modular and set into a metal frame, the barrier can be built in short bays and stepped or angled to follow the curve of the deck.
Panels and frames are lifted to deck level with a boom lift, then aligned and bolted into place along the outer edge of the structure.
If you are planning a noise barrier along an elevated bridge or viaduct, send us your alignment and requirements and our team will help you select the right metal noise barrier panels for the job.

The Vietnam North-South Expressway Noise Barrier project aims to mitigate traffic noise pollution for communities along the expressway while enhancing road safety and environmental sustainability. By installing high-performance noise barriers with optimized acoustic designs, the project addresses urban and rural noise concerns, aligns with Vietnam’s infrastructure modernization goals, and improves quality of life for residents.
In 2024, Macao launched a forward-thinking infrastructure initiative to address noise pollution challenges along the A2 Bridge, a vital transportation link connecting key urban and economic zones. The project underscores Macao’s commitment to balancing rapid urban development with environmental sustainability and community well-being.
