How will the proposed test noise wall impact the construction? If the test wall is effective, will INDOT create a policy on when they will be used?
Separate from the 465/69 Northeast project, INDOT is pursuing a Federally-funded research project to identify cost-effective alternatives for blocking highway noise and visibility along residential areas. The study will compare the performance of traditional urban noise barriers – like those used in the 465/69 Northeast project – against less expensive wall or fence materials. The test barrier wall is proposed to be constructed on the south side of I-465 between Kerwood Drive and Haverstick Road. Surveys of nearby residents will be conducted before and after installation of the test materials to gauge residents’ satisfaction with the performance of different barrier materials. The research findings will be considered by INDOT in future noise policy revisions, but no changes will be made to the current noise barriers that will be constructed as part of the 465/69 Northeast project. INDOT plans to submit its final research proposal to the Federal Highway Administration by the end of 2010
