FRT 236: Evaluation of Noise Reduction Alternatives for Brent Spence Bridge Corridor Project

Abstract FRT 236, Evaluation of Noise Reduction Alternatives for Brent Spence Bridge Corridor Project 10/1/22 – 3/31/23 The proposed project would provide KYTC with a report that provides a synopsis of current best state-of-practice for noise reduction and potential mitigation efforts on both roadway pavement and bridge structures post Louisville Southern Indiana Ohio River Bridge Project (LSIORBP). The project shall look at specific benefits and drawbacks of permeable friction courses (one of the types of pavements). KTC project report shall provide background information that includes a summary of noise abatement options and previous studies. Noise impacts due to transportation structures is a cause of concern for populations living near those structures. FHWA regulates the highway traffic and construction noise through Title 23 CFR 772 rule that requires each state highway agency (SHA) to revise its noise policy to be in accordance with this final rule. The new proposed companion bridge to the Brent Spence Bridge in northern Kentucky that carries I-71 and I-75 traffic across the Ohio River will provide an additional river crossing to the west of the existing structure. In addition to reducing congestion, improving safety, and increasing access to the central business districts and local communities throughout the corridor, current plans call for the separation of local and through traffic. Local traffic will use the existing Brent Spence Bridge and through traffic will use the new companion bridge.
