Ann Arbor’s downtown is turning into a summer-long street party and you’re invited. From June 5 through August 31, A2 Summer Streets transforms downtown Ann Arbor into a walkable, music-filled destination every weekend, thanks to the Main Street Area Association. With streets closed to cars Thursdays at 4 PM through Sundays, you get room to roam, shop, dine outdoors, and catch some incredible live performances.
