Jackson County road map A road map of Jackson County is indispensable for birding in Jackson County. This is especially true for birding in the eastern half of the county because of the large number of lakes and the small number of long, straight, north-south and east-west roads. To get a free road map of Jackson County, go to the Jackson County Road Commission. It is at 2400 N. Elm Road, Jackson, MI 49201. Take I-94 west from Ann Arbor. The Elm Road exit is nearly all the way in to Jackson. It is the second exit after U.S. 127. Go north on Elm Road. The Jackson County map is not as nice as the Washtenaw County road map available from the Washtenaw County Road Commission, but it's good enough. Get one if you can get to the road commission office on a weekday.
