History
The first portion of what would become SH-115 was added to the state highway system in 1939 as part of SH-49. At this time, SH-49 began at US-62 in Cache proper (US-62 had not yet been shifted to the freeway north of town), entered the Wichita Mountains National Wildlife Refuge, then emerged near

and followed the remainder of SH-49's present day routing.
The majority of SH-115, the entire extent from the SH-49 junction in the National Wildlife Refuge to Cowden Junction, was commissioned in 1957. As originally added to the system, only the portion of highway between the northern SH-19 junction and the Washita River bridge was paved. The remainder of the route, comprising the entirety of its route within Comanche and Washita Counties, was gravel. The section of SH-49 connecting to Cache to the refuge was renumbered to be part of SH-115 in 1962, giving the highway the same basic routing that it has today. The remaining gravel portions of highway were paved between 1965 and 1967.
In 1964, the portion of gravel roadway through the Wichita Mountains between Meers and the Comanche–Kiowa County line was removed from SH-115. The SH-115 designation would not be restored to this section of highway until 1984, by which time it had been paved.
