Oregon Route 99 is a state highway that runs between the southern border of Oregon, and the city of Junction City. Oregon Route 99 was formed from parts of the former U.S. Route 99; it shares much of its route with I-5, but much of it is also independent. Between Portland and Junction City, the highway is forked into two routes: Oregon Route 99E and Oregon Route 99W.
