OCPR has posted an official map of the connector route through Addison Oaks and over to Indian Lake Rd. You can see it here.
To quote DestinationOakland's Addison Oaks page:
Beginning May 2012, Oakland County Parks and Recreation will initiate construction on the Addison Oaks “Connector Trail." Funded in part with a grant from the Michigan Natural Resources Trust Fund, this 2.4-mile long trail will provide a non-motorized connection between the “Main” and “East” sections of Addison Oaks County Park.
The trail will run adjacent to portions of West Romeo Road and northwest through portions of the existing park. It will also provide direct access to trails at Cranberry Lake Park in Oakland Township.
When completed, the Connector Trail will be open to pedestrians, bicycles and equestrians, utilizing a combination of crushed limestone, grass, and boardwalk surfaces.
During construction, the trails in the East Unit of Addison Oaks will be closed; access to portions of the trails in the Main Unit of the park may also be temporarily closed. Anticipated completion is Fall 2012.
