This is a map of the state highways in Washington as they existed in 1937. Primary routes are red and secondary routes are purple. Thin orange is just current routes. <a href="//commons.wikimedia.org/wiki/Special:EmailUser/NE2" title="Special:EmailUser/NE2">Email me</a> if you would like a copy of the GIS data I created for the highways.
