Interstate 5 travels north-south from California through the Willamette Valley to Portland, then crosses the Columbia River into Washington. I-5 replaced the routing of U.S. 99 throughout most of western Oregon. The freeway enters the state south of Ashland and stays west of the Cascade Range from Siskiyou Summit north to Portland. Along the way are the communities of Medford, Grants Pass, Roseburg, Eugene, Salem, and Portland.

||Although many of the Oregon 99 overlaps with Interstate 5 are unsigned, the overlap between the freeway and Oregon 138 is acknowledged. The state route combines with I-5 across the Umpqua River northward 12 miles to Sutherlin. Photo taken 04/01/05. |
