The annual report highlights another strong year of infrastructure investment focused on roads, bridges, and drainage systems across the county. A total of $13.06 million in revenue supported $12.22 million in expenditures, with most funding coming from gas taxes and motor vehicle license fees. No property taxes were used for county road or bridge improvements, keeping the focus on road user funding.

Road improvement remained the top priority in 2025, with significant spending on resurfacing, road widening, and pavement preservation. Projects included full asphalt resurfacing and pavement widening on Fort Recovery–Minster Road, along with chip and seal or fog seal work on more than 39 miles of county roads. County crews also completed additional resurfacing work on township roads, extending pavement life and reducing long-term maintenance costs.

Bridge and drainage infrastructure also saw continued investment. Crews completed multiple bridge replacements, large culvert projects, and deck waterproofing work to extend structure lifespan. Drainage efforts included ditch maintenance, erosion control along Beaver Creek, and the addition of new ditch and tile projects to the permanent maintenance system, improving water management for agricultural and residential areas

The report also highlights the role of experienced county personnel and strategic equipment investments in keeping costs down while maintaining service levels. With an average employee tenure of more than 15 years and a long-term goal of widening all county roads to at least 24 feet by 2044, the Mercer County Engineer’s Office continues to emphasize safety, efficiency, and long-range planning for the benefit of all residents.
