Noise barrier construction is now underway and are expected to occur over several years as different sections of the mainline are completed. For additional information on barrier locations, anticipated construction timelines, and the noise analysis process used to determine barrier eligibility and design, check out the information below. Please note that construction schedules are determined by contractors and are subject to change.
WisDOT completed a full noise analysis during the preliminary design and environmental review phases of the I-41 Project, with results and proposed barrier locations shared in the Environmental Assessment and at a 2021 public hearing. A re-evaluation in fall 2023 confirmed these findings following design updates.
A public information meeting was held on January 23, 2024 for property owners and tenants near proposed barriers, with voting open through February 29, 2024. A simple majority supported each barrier, so all will be constructed as part of the project. Minor adjustments to Barriers 1A and 9 do not affect benefited properties.
