Oregon Route 99 marker

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 Interstate 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.

Oregon Route 99 technically starts at an interchange with Interstate 5 at exit 11, south of Ashland. There it departs from the freeway, running parallel to I-5 as it passes through the cities of Ashland (as Main Street), Talent, Phoenix, and Medford. The highway rejoins I-5 at exit 35, just Northwest of Central Point.

OR 99 departs from I-5 several more times through the mountains of southern Oregon, only to rejoin again a short distance later. Junctions are found in Gold Hill (2nd Ave), Grants Pass, between Myrtle Creek and Sutherlin (crossing I-5 in Roseburg, Oregon), through Drain and Yoncalla, and Cottage Grove and Goshen. These departures serve as business routes for I-5, as Oregon does not have or sign Interstate business routes.
