Project Information

Some highlights of the Selected Alternative include:

  • The I-75/I-375 interchange would be an urban-type interchange with right-hand on and off ramps that would provide access to the Eastern Market, Gratiot Avenue, the new boulevard, Brush Street, and Mack Avenue. This would eliminate the need to exit the freeway to stay on I-75.
  • A city street-level boulevard would begin south of the I-75/I-375 interchange and continue to the Detroit River, opening up additional connections to the Detroit Riverfront, Eastern Market, Brush Park, and a new local connector street from Eastern Market to Gratiot Avenue.
  • Braided ramps to and from Mack Avenue on I-75, meaning the ramps would pass over other ramps to and from the boulevard using bridges to separate the roadways and ramp traffic, eliminating weaving, or conflict points.
  • Additional connectivity and access would be provided with a new bridge connecting Brush Park and Eastern Market, additional street connections in Eastern Market, and access to Brush Park from southbound I-75.
  • Improved nonmotorized facilities, including a two-way cycle track connecting the Riverfront to the Montcalm Street extension to Gratiot Avenue. The two-way cycle track would then extend west to Brush Street and east to Gratiot Avenue where it connects with the Dequindre Cut Greenway bicycle path.
  • Potential excess property that could be available for future redevelopment.
  • Signalized intersections would be located along the boulevard at Jefferson Avenue, Larned Street, Lafayette Avenue, Monroe Street, Macomb Street, Clinton Street, Gratiot Avenue, and at the Blue Cross Blue Shield parking structure.
