AZ 51

State Route 51 is named the Piestewa Freeway in honor of Private First Class Lori Piestewa, who was the first Native American woman to die in combat in the U.S. Military. SR 51 travels through the Piestewa Peak Recreation Area, also named for the same reason. Previously, the freeway and peak were named Squaw Peak Parkway and Squaw Peak. This was changed in 2003 as the word "squaw" is considered offensive by many Native Americans.
