Metal Louvre Noise Barrier Project-Changzhou Southern Highway
The Su-Xi-Chang Southern Highway is a pivotal link in the Yangtze River Delta’s transport network, spanning 43.9 kilometers from Changzhou to Wuxi. Designed to six-lane highway standards with a roadbed width of 34.5 meters, this high-capacity artery facilitates regional economic integration. The project includes sophisticated engineering features such as the 10.79 km Taihu Lake Tunnel and the 1.43 km Yaoxian Mountain Tunnel, requiring a high-performance noise mitigation strategy for its open-road segments.

Challenges
The Changzhou-to-Wuxi segment involves a complex layout of 7 interchanges and multiple service areas. Operating as a major logistics corridor, the expressway handles high volumes of heavy-duty and passenger vehicle traffic. The primary challenge was to implement an extensive noise barrier system (Contract Section SPZ20-CX1) that could maintain acoustic efficiency across varied terrain, including bridge-to-tunnel transitions and high-speed interchanges, while ensuring long-term durability against extreme weather and wind pressure.
The Solution
To support the environmental goals of this regional expressway, our company provided a comprehensive manufacturing and installation solution:
- Customized Section Delivery: We successfully managed the SPZ20-CX1 contract section, delivering specialized noise barriers tailored to the specific geometric requirements of the Changzhou and Wuxi segments.
- Structural Resilience: Each barrier unit was engineered to withstand the unique aerodynamic loads generated on a 34.5-meter wide, six-lane high-speed corridor, utilizing premium materials for maximum corrosion resistance.
- Seamless Interchange Integration: Our installation team ensured that the barriers integrated perfectly with the 7 interchanges and 4 ramp toll stations, providing continuous acoustic protection without interfering with traffic safety or signage visibility.
Execution and Outcomes
Our company’s end-to-end execution—from production to on-site installation—guarantees superior noise reduction for the residential and ecological zones adjacent to the Su-Xi-Chang Southern Expressway. By fulfilling the rigorous technical standards of the SPZ20-CX1 tender, we have contributed to a quieter, more sustainable transport corridor that balances rapid regional connectivity with environmental responsibility.
