Do you trust local government officials to ensure safety when reopening public trails with sinkhole issues?
The city of Ann Arbor has reopened a segment of the Border-to-Border Trail connecting the Gallup Park fishing pond and Geddes Dam. The trail had been closed to ensure public safety after staff discovered sinkholes caused by failing stormwater infrastructure.
Why it matters
The trail was closed as a safety precaution because soil had migrated into deteriorating culverts, creating dangerous voids beneath the path. Restoring access allows local residents to resume outdoor recreation along the Huron River while the city evaluates permanent repair options.
City staff identified sinkholes above stormwater culverts in July 2026, leading to an indefinite closure of the segment in September 2026. The site reopened after crews installed interim stabilization measures.
The players
Ann Arbor Parks Department
The local government agency responsible for managing city trails and maintaining public outdoor safety.
The details
The sinkholes developed because deteriorating stormwater culverts beneath the trail allowed soil migration, which created unstable voids. To facilitate reopening, city crews implemented interim stabilization measures to secure the area. Pedestrians and cyclists can now use the path, though city workers remain on-site to continue maintenance and monitoring work alongside the trail.
Timeline
• July 2026: City staff identified the initial sinkhole.
• September 2026: The city closed the trail segment indefinitely.
• October 13, 2026: The trail segment officially reopened to the public.
Health Landscape
This project reflects the broader challenge of maintaining public pathways that intersect with aging municipal stormwater infrastructure. It highlights how cities must balance immediate public access to outdoor recreation with the complexities of long-term structural integrity.
While the trail is now open for walking and cycling, remain aware of crews working alongside the path and follow all posted safety signs. If you encounter any new surface irregularities or signs of ground instability while recreating, report the location to the Ann Arbor Parks Department.
The takeaway
Maintaining situational awareness is key when using public trails that are undergoing active maintenance or recent stabilization. Observe all construction signage and report any new trail hazards to city officials to help ensure continued safe access for all residents.
