South Riverfront Park is located on the south side of the River within the City's downtown area, behind the former Alpena Power Company building, Federal Building, and Memorial Hall. With approximately 850 feet of Thunder Bay River frontage, the site consists of three parcels of land.
In 2005, the amenities of the entire park were upgraded with grant funds received from the State's Cool Cities Pilot Program. A colored, stenciled concrete walkway, the first phase of the City's historic riverwalk, was constructed. Wrought iron safety railing was installed along the head pier and an irrigation system was installed throughout the park. Historic-style pedestrian lights, gazebo, drinking fountain, and wrought iron benches were also installed. Historic markers detailing the history and use of the Thunder Bay River were developed in partnership with the Thunder Bay National Marine Sanctuary and Underwater Preserve and installed along the new walkway.
