Not much of interest exists alongside Interstate 10 west of Phoenix to the Colorado River and California State line. One notable oddity is the underpass of Sore Finger Road which can be found in La Paz County at approximately Mile Marker 60. Sore Finger Road is a primitive dirt road which begins at Salome Road and extends southwest to the vicinity of the Hovatter Airfield.
The Sore Finger Road name allegedly come from a rock formation south of Interstate 10 which resembles a sore finger. The origin of the Sore Finger Road name was reported on September 28, 2015, in a AZcentral news story by Clay Thompson. The article served as an updated report from an earlier story which speculated on the origin of the Sore Finger Road name. The citation of the namesake "Sore Finger" rock formation is attributed to Herbert Winograd.
From westbound Interstate 10 a "Sore Finger Road" placard can be seen affixed to an overpass structure.
