Grist Mill Bridge, Dam and Mill Site

Grist Mill Bridge, Dam and Mill Site comprises three distinct structures: a metal truss bridge on Upton Road, a dam that created a mill pond, and the foundation remains of the Kellogg Bros. & Johnson Mill. The site now functions as a park where visitors can observe the remnants of this working industrial landscape.

The site began in 1865 when Kellogg Bros. & Johnson purchased the property and converted an existing sawmill into a flour and grain mill. This transformation expanded production capacity and established the complex as a major processing center for the region.

The mill complex served as a gathering place where local farmers brought grain to be processed and connected with neighbors. This site anchored the agricultural economy of the township, making it central to how farming families organized their work and trade.

The site is now a public park maintained by Duplain Township and the Elsie Lions Club, freely accessible to visitors. Walking around the grounds works best in fair weather, allowing you to see all three structures comfortably.

The Upton Road Bridge stands as one of Michigan's last metal truss highway bridges and was built by the Detroit Bridge & Iron Works company. This 19th century engineering structure reveals the technical skill of that era and remains a rare survivor of its design type.
