The concept of the sound barrier and how it works is remarkably simple.
Highway sound barrier walls cost per mile.
Each state has a different threshold for what triggers the need for a reasonable intervention.
This translates into a fourteen foot high wall typical costing about 3 9 million dollars per mile.
But how do these walls work and what led to their development.
The average cost per mile for the walls is 1 8 million in ohio.
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.
According to the federal highway administration the average cost of building a sound wall is 30 78 per square foot.
Highway walls are expensive running more than 2 million per linear mile for one side of the highway rymer said.
Construction costs for rural barriers may be lower and urban barriers may be much higher.
If the road noise 200 feet from the highway hits the threshold of 67 decibels then odot must consider building a noise barrier.
The barriers are largely made of concrete and cost over 2 million per mile with some 6 billion spent on them through 2013.
For me though the most astounding figure in the story is that some.
Take a peek at the soundwall project showcase.
If the road noise 200 feet from the highway hits the threshold of 67 decibels then odot must consider building a noise barrier.
Sound wall in california by michael patrick cc by sa 2 0 a 2010 survey by the federal highway administration counted 2 748 linear miles of noise barriers built along highways in the u s.
Current construction costs average 51 61 per square foot.
Disadvantages of concrete highway barriers.
The average cost per mile for the walls is 1 8 million in ohio.
The sound waves hit the wall and the reflective surface of the concrete causes the sound wave to go in the opposite direction.
Between 2008 and 2010 roughly 554 million worth of sound walls were built.
