A section of the Richardson Highway in Alaska was relocated in 2015 by the Alaska DOT in anticipation of erosion or flooding by the nearby Delta River. However, the old highway is still present, is still paved, and is shorter than the new highway that replaced it. OSM mapper Will Lenz classified the old highway as a track to "persuade" his GPS's routing algorithm into using the new section.

Will's idea works but is not, strictly speaking, proper. </font></div><div><br></div></div></blockquote><div>From the imagery, it certainly would fit the highway=unclassified. Since the new road isn't visible, do you know if the old road is paved up to the primary road on both ends? If it is, then yes, its an unclassified road.</div><div><br></div><div>It might help routers to have add maxspeed.
