Route description

SR 287 begins in Florence at a "Y" junction with SR 79 Business near the southern end of town. The route proceeds westbound to Coolidge as the Florence-Coolidge Highway. Upon reaching Coolidge, SR 287 overlaps State Route 87 as Arizona Boulevard, and travels several miles directly south until diverging westward to Casa Grande (where it is known as Florence Boulevard). It terminates there at its junction with State Route 387 and State Route 84.[1][2]

History

The route between Florence and Coolidge was numbered as SR 287 in 1932. At that time, it was an unpaved road.[3] By 1934, it was paved in the segment it was designated.[4] In 1961, the section to Casa Grande was added to the designation.[5]

Junction list

The entire route is in Pinal County.
