State Route 287, also known as SR 287, is a predominantly east–west state highway in central Arizona. Originally, this highway number only applied to Florence-Coolidge Highway; the branch to Casa Grande was added later.
Route description
SR 287 begins in Casa Grande at an interchange with I-10 near the eastern end of town. The route proceeds eastbound until it overlaps State Route 87 as Arizona Boulevard. The highway travels several miles directly north to Coolidge, until splitting from SR 87 and diverging eastward to Florence, where it terminates at SR 79B.[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] The section between I-10 and SR 84 / SR 387 was truncated in the 2020s.
Junction list
The entire route is in Pinal County.
