About SnagMP

SnagMP is a tool to quickly and accurately locate State Route and Milepost values. The data used in the application aligns with the Washington 2019 Highway Log and is limited to Washington State.


Map View

Zoom in to the map and click a location on a State Route. The State Route, Milepost and ARM values are returned to the nearest one hundredth of a mile. The Township/Range/Section data is also returned for the selected point. Consistent with Google Maps, you can toggle the satelite image on/off or utilize street view. When viewing the aerial image you can remove the route lines by unchecking the "Labels" box under the "Satelite" tab.

Search Tool
