Average Cost per Square Foot

Noise Barriers Constructed 1963-2022

This graph shows the average cost for all barriers constructed each year between 1963 and 2022. The overall average cost for the entire reporting period was $32.56. After 2000, costs are consistently above this reporting period average. From 2000 to 2016 the overall average cost is $38. The lowest average cost for a year was in 1963 with a $10 average; the highest was in 2011 with a $49 average. Exact data in table below.

These years include the data for barriers that were later demolished or replaced since those expenditures did occur at that time.
Many barriers had no reported costs in this year, thus totals and averages may not reflect actual costs
* = Does not include any barriers that did not report a 'Year of Original Construction'
** = sums may be higher in cases where States added barriers that were not previously reported. Also, the total is higher than the Master table due to rounding.
