A11 – PK027 + 730

Hatko Sound Barrier has completed another international noise barrier project in Portugal, this time along the A11 Highway.

The project features green-surfaced acoustic barrier panels designed to reduce highway noise while visually integrating with the surrounding urban and roadside environment. In addition to its acoustic performance, the system offers a durable and aesthetic solution for infrastructure areas where noise control and environmental harmony are equally important.

Installed along a busy road corridor, the barrier system helps minimize the impact of traffic noise on nearby living spaces and public areas. Its modular structure, strong support system, and natural green appearance reflect Hatko Sound Barrier’s approach to combining engineering performance with sustainable design.

This A11 Highway project further strengthens Hatko Sound Barrier’s international project experience and demonstrates the company’s capability to deliver reliable, long-lasting, and visually compatible noise control solutions for modern transportation infrastructure.

Hatko Sound Barrier continues to support quieter, safer, and more sustainable road environments across international markets.
