Porter Hollow Embankment and Culvert

The Porter Hollow Embankment and Culvert, also known as the Grand Rapids and Indiana Railroad Culvert, is a stone bridge and trestle over the Stegman Creek along the White Pine Trail in Algoma Township, Michigan.

Porter Hollow was an unincorporated community along this route, about 3 miles north of Rockford.

[2] That stone bridge withstood the rigors of railroad use for nearly a century, and it is in good condition today.

The trestle is listed on the National Register of Historic Places, and is a key bridge along the White Pine Trail.

[3] The Porter Hollow embankment is a 1400-foot-long earth structure, which contains a stone arch culvert passing over Stegman Creek.

"The Grand Rapids and Indiana Railroad (GR&I) reached Algoma Township in 1867. A series of wooden trestles were built to cross Wicked Creek, later named Stegman Creek. In 1885, after repeated fires and floods, the GR&I hired James House to cut fieldstones from his farm and build this culvert to stabilize the trestle. Eventually, the GR&I abandoned the trestle and buried it intact within a wall of dirt above the culvert."
