WisDOT completed a full noise analysis in July 2020 during the preliminary design and the environmental documentation phase 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.
During the final design phase of the project, WisDOT completed a reevaluation to confirm noise findings, taking into account design updates that have been made since the environmental phase was completed. Confirmation of the noise analysis is a key step, as it optimizes the details of the proposed barriers, enables minor adjustments to accommodate site conditions, and evaluates options for potential cost savings.
For more information on the noise analysis process and proposed barriers, check out the story map below:
Nine new noise barriers were determined to be reasonable and feasible (see map below).
Votes were tallied, and the majority of residents and property owners are in support of each proposed noise barrier, so they will be constructed as part of the mainline construction of the project. Thank you for your input!
A public information meeting was held on Tuesday, January 23, 2024, for benefited property owners and tenants located in the immediate vicinity of each proposed barrier. WisDOT mailed meeting invitations and voting materials to the surrounding properties.
The meeting provided details on the noise analysis and voting process, and had staff available to answer questions regarding specific property.
Benefited receptors were asked to vote to confirm whether the barrier should be constructed as part of the I-41 Project by February 29, 2024.

WisDOT completed a reevaluation last fall 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.
