mileposts

A milepost is a marker used to indicate a specific distance or location along a route, such as a road, highway, trail, or railroad. Mileposts are usually numeric markers that record the exact distance from a fixed point, known as a reference point, along the route. The reference point is typically located at the origin of the route and is often marked with a zero or a specific number.

Mileposts serve several purposes, including providing information to travelers about their location and distance to their destination, as well as assisting in navigation and wayfinding. They are also often used as reference points for work crews, emergency responders, and maintenance personnel to determine the location of specific features, such as culverts, tressle bridges, or utility poles.

Mileposts can take various forms, including painted or mounted markers on roadside signs, discreet embedded markers along the route's surface, or incorporated into the route's physical features, such as stone or wooden benches. In rural areas, mileposts may be standalone signs or posts, while in urban areas, they may be incorporated into lampposts or other street furniture.

The use of mileposts dates back to the early days of road construction, when precise measurement and wayfinding were crucial to the safety and efficiency of travelers. Today, mileposts continue to play an important role in transportation infrastructure, assisting both drivers and other stakeholders in understanding the location and distance along various routes.

In some countries, the placement and meaning of mileposts can vary, reflecting local regulations or cultural practices. Despite these variations, however, the basic concept of a milepost remains a ubiquitous feature of transportation systems worldwide.
