Each Interstate route begins at its most westerly or southerly point; this beginning point is milepost 0. If the first interchange on the route is located between milepost 4.0 and 5.0, it is numbered Exit 4. The next interchange, if located at milepost 8.7, is numbered Exit 8, etc. Each mile of the Interstate is marked with a small green “Milepost” marker, so travelers can always see where they are. Most U.S. Highway routes begin at their most westerly or northerly point; this beginning point is milepost 0. So both U.S. 101, the Oregon Coast Highway, and U.S. 97, The Dalles-California Highway, begin at Oregon’s border with Washington State and the milepoint numbering increases as you head south. U.S. 30, however, begins in the Portland area and then runs northwest. And U.S. 26 is a moniker on several highways, so the milepoint numbering starts over—but it runs from west to east, as expected. Oregon highway routes also usually begin at their most westerly or northerly points, but fair warning: there are exceptions (such as OR 35), and there are cases where highway mile numbering starting over on what appears to the general public as the same road. So the location of Milepost 0 may vary; and ‘exits’ are not usually marked with numbers because there are so many intersections (and few if any grade-separated interchanges) on these kinds of highways. But you’ll often still see milepost markers on the side of the road.
