The Wawawai area was a community for Chinese laborers working on nearby farms located on the Snake River, founded in 1875. The community was serviced by the Snake River Valley Railroad that connected Lewiston, Idaho to Washington state. The Wawawai Road was an unpaved dirt road by the 1960s, before the Port of Wilma was established and built. The highway from U.S. Route 410 (US 410) in Clarkston through Wawawai and to US 195 west of Colton was signed as Secondary State Highway 3G (SSH 3G) in 1969.
