WisDOT completed a full noise analysis during the preliminary design and environmental documentation phases of the I-41 Project. The results, along with proposed barrier locations, were published in the I-41 Project Environmental Assessment and presented at the public hearing in 2021.
WisDOT completed a re-evaluation in Fall 2023 to confirm noise findings, after taking into account design updates that have been made since the original environmental assessment was completed.
A public information meeting was held on January 23, 2024 for benefited property owners and tenants located in the immediate vicinity of each proposed barrier. Benefited receptors were asked to submit their votes by February 29, 2024. After votes were tallied, a simple majority was recorded in support of each noise barrier, so they will all be constructed as part of the project. Minor limit changes have been made to barriers 1A and 9 that do not affect the benefitted status of impacted residences.
