Do all precast concrete noise barriers utilize precast concrete posts?
No, noise barriers can be built using concrete posts or steel H beam posts, or they can be freestanding using a serpentine design along the centerline of the noise barrier that offsets wind loads. Noise barriers constructed in a serpentine pattern also provide additional space for landscaping along the roadway. Noise barrier panels have also been mounted on specially designed concrete highway barriers when right-of-way is limited, while lightweight precast concrete noise barriers may be mounted to bridge structures.
