Center: view from the state line, looking back into Oklahoma
Right: first assurance sign for OK-3. The green sign in the distance refers to this road as "Governor George Nigh's Northwest Passage," as OK-3 is called all the way to just south of Okarche, where it turns into the Northwest Expressway.


Eastern Terminus: Arkansas State Line (continues as AR-32)

After looking through several road-related newsgroups, this is the longest state highway I know all of the lower 48. Purists don't agree because of the 3E/3W split (shown in the map above in purple and orange), but if you follow the 3E route (one, because it's longer; and two, because this is the direction OK-3 took before the E/W split back in the 70s) this highway runs for 616 miles, longer than even any state highway in Texas!
