Noise barriers

At the start of a state highway project, the Wisconsin Department of Transportation (WisDOT) determines noise impacts and evaluates possible mitigation measures, such as noise barriers.

After careful evaluation and a voting process, WisDOT installs noise barriers along portions of state highways to minimize noise impacts.

If a simple majority of the benefited receptors (properties with 8dB reduction) approve, noise barriers will be constructed in various locations in the Zoo Interchange corridor.
 

• West Allis - along I-894, noise barriers are being considered for areas north and south of Greenfield Avenue.
• Milwaukee - barriers are proposed along I-94 between the core of the interchange and 70th Street, and along residential areas adjacent to the core of the interchange.
• Wauwatosa - on US 45, in the north leg of the corridor, barriers are proposed north of Bluemound Road.

   

These locations were selected based on a noise analysis that predicts future noise levels. More resources
