Port Milwaukee Project

Project Update

The project begins construction mid-summer, with completion expected by the end of 2025. A variety of green infrastructure practices will be used to manage highway runoff onsite, keeping it out of Lake Michigan. These include native plantings, bioretention basins, and additional stormwater trees.

During construction, there will be:

• No full roadway closures.
• Limited temporary local lane closure.
• Limited temporary I-794 shoulder closures.
• •Grading, utility, and landscape work anticipated.
• Soil will be hauled off; dump truck traffic to be expected.

Please see the traffic plan for more detail.

Project Overview

The Port Milwaukee Overpass Project is the fourth Green Highways project to address highway stormwater runoff. Untreated, highway stormwater runoff carries a variety of pollutants, including vehicular fluids, salts, and particulates from exhaust, tires, and pavement, to nearby waterways and Lake Michigan.

The stormwater runoff will be redirected to a variety of green infrastructure practices that will keep the stormwater on-site. Early designs note that the site lends itself well to the use of bioswales, stormwater trees, and native plants. Skillfully designed green infrastructure practices will also enhance this “gateway” to Milwaukee.
