Castle Road
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.
