NH 115A intersects Whipple Road and Israel's River Road, designated New Hampshire Route 115B but sparsely signed as such, a continuation of the Turnpike Road, built by Colonel Whipple for access from the village of Riverton (Jefferson Mills) to Portland, Maine in the late 18th century.
The local name of NH 115A is Meadows Road, as it once served the Jefferson Meadows train station and post office.
