Alternative Noise Barrier Approvals
The Illinois Center for Transportation at the University of Illinois at Urbana-Champaign has released a report that analyzes alternative noise barriers. Current Illinois Department of Transportation (IDOT) specify that noise barriers can be constructed of earth, masonry, concrete, and composite materials. The objective of this report is to develop recommendations that provide guidance to IDOT on expediting the approval process of alternative noise barriers.
