Wuhan Moshuihu North Road Elevated Noise Barrier
The Moshuihu North Road elevated section is a landmark infrastructure project, recognized as the longest “air tunnel” on the Wuhan Second Ring. This project provides a critical soundproofing solution for the urban expressway, winding through the city like a dragon to ensure noise protection for the surrounding community.

The Challenge
The Moshuihu North Road project (stretching from Longyang Avenue to Jiangcheng Avenue) required a massive, fully enclosed acoustic barrier to manage high-volume traffic noise. The scale of the project was unprecedented at the time, demanding a structural design capable of spanning distances up to 45 meters while maintaining safety and durability.
Solution
To meet these large-scale engineering needs, a specialized fully enclosed barrier system was implemented:
- Advanced Materials: The structure combines micro perforated acoustic panel with high-durability acrylic panel to maximize sound absorption while allowing for light transmission.
- Structural Engineering: The project utilizes submerged arc welding and unequal H-beams to support the wide spans required by the elevated road layout.
- Scale and Design: With a maximum span of 45 meters, this installation was established as the largest elevated, fully enclosed noise barrier project in the country at the time of its construction.
Execution and Outcomes
The completion of this noise barrier has created a quiet corridor along one of Wuhan’s busiest expressway segments. By successfully implementing a 45-meter span design, the project set a new domestic standard for large-scale urban acoustic engineering. This “air tunnel” effectively balances the city’s transportation needs with the environmental comfort of its residents.
