Port Milwaukee Project

Project Update

The Port Milwaukee Overpass Project Green Highways project is complete.

Project Overview

The Port Milwaukee Overpass Project was 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 is redirected to a variety of green infrastructure practices that will keep the stormwater on-site. Design notes 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.

Project Goals

  • To develop a design that addresses highway stormwater runoff through innovative green infrastructure.
  • Leverage green infrastructure design to enhance the Port’s “gateway” to Milwaukee.
  • Coordinate and collaborate with stakeholders and the community throughout the design progress to incorporate community goals.
