The Village of Grass Lake is located in Eastern Jackson County between Ann Arbor and Jackson. The Village lies 2.6 miles south of I-94, which leads to points east and west and provides access to routes running north and south. The Village's main street, Michigan Avenue, which was formerly Old US 12, became simply an east/west route through Jackson County and the Village when I-94 was opened. it remains a main thoroughfare through the area leading to the City of Chelsea to the east and the City of Jackson to the west.
