AZ: AZ 287 shortened in Casa Grande

[rlee]

I recently drove all of AZ 84 from Casa Grande west to I-8 and discovered that AZDOT removed all signage for AZ 287 on Florence Blvd from the AZ 84/387 intersection to I-10. End Maintenance signs were posted a little west of I-10 past the 76 station and one block east of the AZ 84/387 intersection. I didn't get any night time photos, but Google streetview matches up to my observations.

I think AZ 287 should be truncated and start at I-10 i/c. Any objections?
