Slippery Rock Bridge Rehabilitation within Mill Creek Park – ODOT Project No. MAH-Slippery Rock Bridge Rehab; PID 122895

Mill Creek MetroParks, in cooperation with the Ohio Department of Transportation (ODOT), is planning the rehabilitation of the Slippery Rock Bridge on West Glacier Drive within Mill Creek Park, Mahoning County. The project will address deterioration of the existing structure through deck repairs, substructure patching, and the replacement of approach slabs, guardrail, and approach pavement. No widening or realignment is planned.

The $480,000 project is scheduled to begin construction in spring 2026 and is expected to be completed by fall 2026.

During construction, the Slippery Rock Bridge and a section of roadway between West Glacier Drive/West Drive and Robinson Hill Drive/Memorial Hill Drive will be closed to all park users—vehicles, pedestrians, and bicyclists—for up to 90 days. A detour will direct park users to Old Furnace Road, located 0.5 miles south of the bridge. Detour signage will be posted along West Glacier Drive/West Drive and Robinson Hill Drive/Memorial Hill Drive, and updated project information will be made available on the Mill Creek MetroParks website prior to the start of construction.

The Mill Creek Park Historic District is a protected resource under federal-aid transportation regulations. The proposed rehabilitation will preserve and, where possible, enhance the park’s historic and recreational features. While the project will require temporary access-related impacts, including minor work within Mill Creek and selective trimming of trees near the bridge, no adverse long-term effects to protected park resources are anticipated.

As part of the environmental review process, Mill Creek MetroParks is seeking public comments regarding potential social, environmental, and economic impacts of the proposed project. Feedback may address topics including the natural environment, nearby residents, local economic considerations, or historic and cultural resources.

Comments will be accepted through December 26, 2025, and may be sent via email or mail to:
