Arizona State Route 587

State Route 587, also known as SR 587, is a state highway in south-central Arizona that travels from its junction with State Route 87 just south of Sun Lakes directly south to Interstate 10 in Bapchule.

History
The routing of SR 587 existed as early as 1938 as an improved road. The route was not part of the state highway system at this time. By 1951, this road became part of SR 387. By 1961, the route had become part of SR 93, a proposed extension of US 93. The route was redesignated to SR 587 on December 17, 1984 when SR 93 was removed from the state highway system.
