Between 2008 and 2010 roughly 554 million worth of sound walls were built.

Highway sound barrier walls cost per mile.

The concept of the sound barrier and how it works is remarkably simple. Disadvantages of concrete highway barriers. For me though the most astounding figure in the story is that some. Current construction costs average 51 61 per square foot.

Construction costs for rural barriers may be lower and urban barriers may be much higher. According to the federal highway administration the average cost of building a sound wall is 30 78 per square foot. Take a peek at the soundwall project showcase. The sound waves hit the wall and the reflective surface of the concrete causes the sound wave to go in the opposite direction.

This translates into a fourteen foot high wall typical costing about 3 9 million dollars per mile. The average cost per mile for the walls is 1 8 million in ohio. If the road noise 200 feet from the highway hits the threshold of 67 decibels then odot must consider building a noise barrier.

Each state has a different threshold for what triggers the need for a reasonable intervention. But how do these walls work and what led to their development. The average cost for noise barrier construction of this type has been about 12 per square foot of barrier surface or approximately 200 per linear foot of barrier i e a 1 ft. Newer research proves concrete sound barrier walls are some of the worst offenders for creating unwanted and unpredictable reflected noise issues.
