How should we tag routes like this?  Oregon has a few "Detour I-5"
routes on smaller (often two-lane county roads) roads where all lanes
get sent the same direction when some dork talking on their cellphone
while driving gets creamed on the motorway route that are posted (and
often have some normally gated routes that round off what would
normally be a four-way stop).
