By 1976, the section from Pahrump to US 95 was designated as part of the newly-created SR 160. The section from the California border to Pahrump remained as SR 16 until it was removed by 1982 and is now designated Old Route 16. However, satellite imagery indicates the former highway remains almost entirely unpaved and even passes through the runway of an old airstrip built in 1941 by Ronald Wiley, former owner of Hidden Hills Ranch and namesake of the Ronald H. Wiley Archaeological Preserve.
