I10 111.2 MM
West of Phoenix on I10 there are several miles of MMs like 111.2, 111.4, etc. What is that all about?

These MM appear over about a 2 mile distance MM 111 and 112 and are on both sides of I10. There is no apparent reason for their existence that I've noticed. No culverts, bridges, etc and trust me this is not a populated area.
I don't recall this type of sign along interstates. There are exit signs like 1 1/2 miles and there are county signs like 45.21 etc.
