State Route 88 (SR 88) is a 45.67 mi (73.50 km) long state highway in the U.S. state of Arizona. It runs from U.S. Route 60 (US 60) in Apache Junction through desert terrain to SR 188 near Roosevelt Dam. Following the Salt River for much of its length, the section east of Tortilla Flat is known as the Apache Trail and is part of the National Forest Scenic Byway system. The Apache Trail was built in the mid-1920s and the number 88 was assigned in 1927. An eastern extension of SR 88 to Globe was redesignated as SR 188 in the late 1990s.
