county road ends at the intersection with H-58 (Munising–Van Meer–Shingleton Road) in the Pictured Rocks National Lakeshore. As a county-designated highway, H-13 is maintained by the county road commissions of Delta, Alger and Schoolcraft counties (DCRC, ACRC and SCRC respectively) with support for the FFH-13 segment as part of the Forest Highway System that is funded and administered by the United States Forest Service and the Federal Highway Administration. H-13/FFH-13 forms a major north–south artery for the Hiawatha National Forest. History The Forest Highway System was created by the Federal Aid Highway Act of 1921. An earthen road was present along the route of H-13 by the middle of 1936. Later that year, the segment along the Alger–Schoolcraft county line was built as a gravel road, and Miners Castle Road was upgraded to gravel as well. Additional segments were under construction in 1940 in Delta County and south of Wetmore. During World War II, the gravel surface was downgraded to earth along Miners Castle Road. The rest of the modern H-13 was paved in 1948 or 1949. The county-designated highway system was created around October 5, 1970, when the state approved the system. The H-13 designation debuted in 1972 between Nahma Junction and H-58; H-13 turned east and ran concurrently with H-58 before turning north on Miners Castle Road. The northernmost segment was paved in 1987, completing the paving along the entire route. The H-58 concurrency was removed in 2004 when the northern segment of H-13 along Miners Castle Road was redesignated H-11.
