No stretch of SR 616 is included within the National Highway System, a network of highways deemed most vital for the nation's economy, mobility and defense.
[4] The section of SR 616 between US Route 422 and US Route 224, is considered a "principal arterial" highway, and is a "MAP-21" (Moving Ahead for Progress in the 21st century), to be potentially included within the NHS.
From its inception, it has maintained the same Poland–Hubbard alignment that it utilizes today.
There have been no changes of major significance to the routing of SR 616 since it was designated.
