Trunk Line Bridge No. 1

The Trunk Line Bridge No. 1 spans 240 feet across the Peshekee River with six concrete girders supporting a deck near Lake Michigamme.

Built in 1914 as the first bridge designed by the Michigan State Highway Department, this structure marked the beginning of standardized infrastructure development.

The bridge represents early 20th-century engineering methods with its concrete through-girder design and rectangular recessed panels in the girder walls.

While vehicles can no longer access the bridge from US 41/M-28, pedestrians can reach it from the eastern side within Van Riper State Park.

The structure required 600 cubic yards of concrete and features full-height abutments over solid concrete piers with specialized bullnosed cutwaters.
