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?

Mile markers every .2 miles are very common on interstates. Mostly around more populated areas. When you get away from the populated areas they go back to one every mile. In an emergency/accident you don't have to go very far to find a mile marker when calling 911.
Can't believe you've never seen them before.
