Noise Abatement

FHWA regulations for noise evaluation are detailed in Title 23: Highways - Part 772-Procedures for Abatement of Highway Traffic Noise and Construction Noise. The regulations require the consideration of noise abatement mitigation when traffic noise impacts that exceed a defined threshold are identified.  Update: The ADOT Noise Team is currently revising the Noise Abatement Policy, when complete the information will be provided, please refer to noise guidance documents located on the Technical Guidance page under Noise Abatement.

The FHWA regulations require the following during the planning and design of a highway project:

  • Identification of traffic noise impacts and examination of potential mitigation measures
  • Incorporation of reasonable (resident/owner preferences, noise reduction goals, cost effectiveness) and feasible (engineering and acoustic) noise mitigation measures into the highway project
  • Coordination with local officials to provide helpful information on compatible land use planning and control
