Southern terminus: I-44, Exit 100



 
Left: end of OK-4, looking southbound toward the I-44 cloverleaf exits. Continuing straight ahead puts you on the H.E. Bailey Spur, a more direct toll loop towards Norman.

Right: start of OK-4, looking northbound. Technically, this is one of the first assurance signs. The first regular side-of-the-road sign doesn't occur for another two miles.



Northern terminus: Piedmont



Sidebar: the two OK-4's have nothing to do with each other. The eastern OK-4 is so-named because it continues into Arkansas as their SH-4.
