Welcome to the Macomb St. Clair Mega Cruise Chesterfield—an annual celebration that’s much more than just a cruise! On Saturday, September 26, 2026, join us for a day packed with thrilling activities, exciting car shows, and family fun. Whether you’re a car enthusiast, a fitness fanatic, or someone who loves great food and live music, this event offers something for everyone. From muscle cars to customs, food trucks to craft fairs, and even a 5K run, the Macomb St. Clair Mega Cruise Chesterfield transforms Gratiot Avenue into the heart of Macomb County’s most vibrant event.

With over a decade of history, the Gratiot Avenue Chamber of Commerce has raised $100,000 for community groups through this event, and this year promises to be bigger and better than ever. Visitors can look forward to live music, a charity cornhole tournament, and plenty of activities for kids—including inflatables and a chance to meet local heroes like police K9 units.
