It runs from Interstate 84 at Arlington in the Columbia River Gorge to a junction with U.S. Route 26 in Grant County, near the Sheep Rock Unit of the John Day Fossil Beds National Monument. Oregon Route 19 is the northern portion of the John Day Highway No. 5 (see Oregon highways and routes) and follows the John Day River from Service Creek to its southern terminus. The route has two brief overlaps Oregon Route 206 and Oregon Route 207, both on the portions of those routes included in the Wasco-Heppner Highway No. 300.
