Route description

Oregon Route 34 begins (at its western terminus) at its junction with U.S. Route 101 in Waldport. It follows the Alsea River to the town of Alsea, where it then heads northeast to its junction with U.S. Route 20 near Philomath. OR 34 and US 20 share the same roadway between Philomath and the college town of Corvallis. At a grade-separated interchange in eastern Corvallis, OR 34 leaves US 20 (which heads north with Oregon Route 99W) and crosses the Willamette River into Linn County. From Corvallis to its junction with Interstate 5 east of Tangent, OR 34 is a four-lane undivided highway, with an interchange at its junction with Oregon Route 99E in Tangent. OR 34 continues east to its eastern terminus at US 20 in Lebanon.
