Route description
The highway begins in a ghost town of Nutt. Formerly this was the point at which the spur left the main trunk of the Atchison, Topeka and Santa Fe Railway railroad and headed north to a mining community of Lake Valley. For the first 3.700 mi NM 27 runs concurrently with Luna County CR A027. The road passes through the Chihuahuan grasslands between the Nutt and Round Mountains. At 12.9 miles NM 27 reaches a former mining town of Lake Valley. The town is a preserved ghost town most famous for its silver mining. Silver was first discovered here in 1876 and for the period from 1878 through 1931 5.8 million ounces or 180 metric tons of silver was mined. At 17.3 miles the road crosses Berrenda Creek with a few agricultural fields in the vicinity. Shortly after, the road passes by North and South Sibley Mountains named after a confederate general Henry H. Sibley. After passing a 22-mile mark, the highway crosses the Tierra Blanca Creek, and at 23.5 miles Oak Spring Creek. The road then turns further northwest and continues on for the next 5.2 miles before taking a turn to north-northeast right before reaching Hillsboro. At 30.2 miles NM 27 reaches its northern terminus at NM 152.

History
NM 27 was initially a part of the original Route 26 created in 1905 by the Territorial Legislative Assembly. The old Route 26 ran from Deming, through Nutt, Hillsboro, Truth or Consequences to Engle. The stretch from Nutt to Hatch was designated as Route 27. In 1930s the Route 26 was shortened with the northern terminus shifting from Engle to Hillsboro. During early 1940s Route 26 was re-routed towards Hatch, and the road to Hillsboro became Route 27. The road was considered a secondary state route from its early days and remained either "graded" or "gravel" until it was paved some time in 1960s.
