Rotary Island Mill ParkRotary Island Mill Park is located in the Thunder Bay River between Sixth and Seventh Streets. Owned by the Rotary Club of Alpena, this park was developed for recreational use with fishing sites and pathways. In 2007, a pedestrian bridge linking the island to the Great Lake Maritime Heritage Trail was installed. This bridge established a connected, non-motorized pathway to both sides of the Thunder Bay River. It also effectively integrated the island into the City park system. In 2008, the Rotary Club signed a maintenance agreement with the City of Alpena, whereas the City will maintain specified improvements on the island in exchange for a public access easement across the island.
