Blumfield Township and Denmark Township
Although there are no incorporated communities located along M-15 as it passes through Blumfield Township, Saginaw County and Denmark Township, Tuscola County. there are several parks and recreation areas.
Richville
Richville is a small unincorporated community in the southwest corner of Denmark Township. It is at the junction of M-15 and M-46.
Hager Line Rail-Trail
The Harger Line Rail-Trail runs for an arrow-straight 10 miles through farmland in rural Saginaw County. The trail opened in 2008, two years after the underlying Harger Line Railway corridor was acquired by the Michigan Department of Transportation.
The eastern trailhead (which offers ample parking) is located where the trail meets Saginaw Road/ M-15 just west of Richville. The parking lot is on the south side of Saginaw Road/ M-15. Look for the large brown trail sign.
The scenic trail features 5 bridges over creeks and intersects several unpaved country roads. Trail users should be aware that the two major crossings of Portsmouth Road and State Route 83/Gera Road are uncontrolled intersections; extreme caution must be exercised when passing through. Benches along the entire length of the trail allow users to take a rest or simply enjoy the surrounding tranquility.
