~ ODOT, Descriptions of US and Oregon Routes, May 2005
OR-69 was created in September 2002 when ODOT decided to give routes to unmarked Oregon highways, in this case the unmarked Belt Line Highway #69, where the OR-69 comes from. A more detailed history of this highway can be found on my OR-569 page. Despite the new designation, shields were never posted along the route. The routing destination was left in limbo until January 2007, when someone at the Oregon Transporation Commission floated a proposal to renumber the highway, probably due to its risqué numerical nature. After floating the OR-14 designation as a replacement, the OTC decided to change the number to Oregon Route 569, killing the hidden OR-69 designation.
I believe that it is the only truly-hidden Oregon Route designation to have been killed. A shield was never posted on the highway or its intersectors...it was only referred to as OR-69 in internal documents. OR-569 will have shields posted on it in Summer 2007, so it's "child" will live on.
