The I-95/Scudder Falls Bridge Improvement Project includes a noise impact evaluation being conducted in accordance with the Federal Highway Administration’s (FHWA) guidelines and policies. Noise monitoring is underway to document existing noise levels and to calibrate predictive noise models that will be used to predict future noise levels for the project alternatives. If noise levels are predicted to exceed established FHWA criteria, then the consultant team will evaluate the feasibility and effectiveness of noise mitigation. One of the more common noise mitigation measures used in association with highways is a noise barrier, or sound wall. The size, location, and extent of barriers are based on the existing noise levels, predicted noise levels, and the predicted effectiveness of the barrier.
