-based Smith-Byers-Sparks Company in 1913, and the company completed construction of the bridges the next year.

By 1915, the trunkline highway had been nearly completed. In the 1920s, the route was incorporated into what is now US 41. In 1934, the nearby Snake River bride was replaced; US 41 was later rerouted near the Pike River, leaving the original trunk line bridge to service local traffic on the redesignated county road 117.

Desciption

The County Road C117 – Pike River Bridge has a main span 38 feet (11.6 m) long, with a structure width of 21.4 feet (6.5 m) and a roadway width of 19.1 feet (5.8 m). It is constructed of five rolled I-beams supported by concrete abutments at each end. The bridge was developed from a standard design, first delineated by the state highway department in 1905-1906. The steel stringer design was one of the first established by the department, and was used intermittently during the 1910s for relatively short spans.

Standard paneled concrete guardrails are incorporated on each side of the bridge. One of the guardrails includes the cast words, "State Trunk Line Bridge 1914" and another, "Built by S-B-S Company Houghton."

The County Road C117 – Pike River Bridge is in excellent condition, and is essentially unaltered from when it was built. The bride was one of the first trunk line bridges built that used the Michigan State Highway Department's steel stringer configuration. Of the 22 total trunk line bridges the department listed in its 1913–1914 biennial report, almost half were stringer bridges, and of these Pike River Bridge is the only one to remain undemolished and unaltered. This bridge is thus significant as an early unaltered example of this important bridge structural type used in the Upper Peninsula's trunk line system.
