Milestone

A milestone is one of a series of numbered markers placed along a road or boundary at intervals of one mile or occasionally, parts of a mile. They are typically located at the side of the road or in a median. They are alternatively known as mile markers, mileposts or mile posts (sometimes abbreviated MPs). Mileage is the distance along the road from a fixed commencement point.

Milestones are constructed to provide reference points along the road. This can be used to reassure travellers that the proper path is being followed, and to indicate either distance travelled or the remaining distance to a destination. Such references are also used to by maintenance engineers and emergency services to direct them to specific points where their presence is required. This term is sometimes used to denote a location on a road even if no physical sign is present. This is useful for accident reporting and other record keeping (e.g., "an accident occurred at the 13 mile mark" even if the road is only marked with a stone once every 10 miles).

Famous quotes containing the word milestone:

    Every milestone of a firstborn is scrutinized, photographed, recorded, replayed, and retold by doting parents to admiring relatives and disinterested friends. . . . While subsequent children will strive to keep pace with siblings a few years their senior, the firstborn will always have a seemingly Herculean task of emulating his adult parents.
    Marianne E. Neifert (20th century)

    As your baby progresses from one milestone to the next, remember that he doesn’t really leave any of them behind. In order to grow and develop to his full potential he must continually build on and strengthen all of the steps that have gone before.
    Stanley I. Greenspan (20th century)
