Display Field:

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description:

Locations of milepost markers along the State Highway System. Mileposts are used to assist with identifying specific locations along a roadway, such as directing maintenance crews to portions of a roadway in need or repair.

Note, while ADOT makes every attempt to place mileposts at accurate mile locations, landscapes and other factors may require the markers to be placed slightly off from their true locations. It is recommended that mileposts not be used in projects that require high location accuracy. In those cases, engineering stations may be a more suitable alternative.

Reported Extent: Required for the State Highway System (i.e. all ADOT-owned roads). Optionally recorded for all other roadways.
