Noise Barrier Walls

Sound Barrier for State Route 28

McMahon & Mann analyzed the soil property information provided by the Pennsylvania Department of Transportation to design drilled shaft foundations that support the concrete panels and concrete posts. We also used the computer program LPILE to estimate the amount of lateral deflection that the drilled shafts would experience from the applied loads.
