Highway sound barrier walls cost per mile.

Construction costs for rural barriers may be lower and urban barriers may be much higher. 3 have no gaps or holes in or under the barrier that allow road noise to pass through. The total spent on sound walls through 2013 the most recent government figures tops 6 billion. The low installation costs of concrete sound walls leads to an economical buy when compared to metal or wood noise barrier wall applications the sierra wall noise barrier wall system has the additional advantage of being relocated if highway boundaries change.

Current construction costs average 51 61 per square foot. 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. He says that typically precast sound barriers cost anywhere from 25 to 45 per square foot. 4 have an irregular surface to diffuse the sound when it hits the acoustic barrier.

The barriers are largely made of concrete and cost over 2 million per mile with some 6 billion spent on them through 2013. 1 as tall as possible to stop highway noise escaping over the top of the barrier. This translates into a fourteen foot high wall typical costing about 3 9 million dollars per mile. Thus the approximate average cost for a typical one mile long 16 foot high wooden plank noise barrier is about 1 million.

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. Each state has a different threshold for what triggers the need for a reasonable intervention. For me though the most astounding figure in the story is that some.

Between 2008 and 2010 roughly 554 million worth of sound walls were built. Highway walls are expensive running more than 2 million per linear mile for one side of the highway rymer said. 2 as dense as possible to stop road noise passing through the barrier. Usually a barrier costs about 4 million per mile.
