Noise Barriers Inventory Request

The FHWA noise regulation (23 CFR 772) gives each state department of transportation (SDOT) flexibility to determine the feasibility and reasonableness of noise abatement by balancing of the benefits of noise abatement against the overall adverse social, economic, and environmental effects and costs of the noise abatement measures. The SDOT must base its determination on the interest of the overall public good, keeping in mind all the elements of the highway program (need, funding, environmental impacts, public involvement, etc.). FHWA will be creating an inventory of noise barriers by requesting information in 2014 (for noise barriers constructed in 2011, 2012 and 2013) and then again in 2017 (for noise barriers constructed in 2014, 2015 and 2016).
