Oregon Route 42

Oregon Route 42 is an Oregon state highway which runs between U.S. Route 101 on the Oregon Coast, near Coos Bay, and Green, a few miles south of Roseburg on Interstate 5. It is known as the Coos Bay-Roseburg Highway No. 35 (see Oregon highways and routes). At Coquille, there is a split in the route, as Oregon Route 42S heads southwest toward Bandon. The largest towns on the route are Winston, Coquille, Myrtle Point, and the unincorporated community of Green. Oregon Route 42 is the southernmost reliable link between the Oregon Coast and the Interstate 5 corridor, although the notorious Bear Camp Road is farther south.

The section of Oregon Route 42 between its junction with U.S. Route 101 south of Coos Bay and its junction with Oregon Route 42S in Coquille was once a part of U.S. Route 101. When U.S. Route 101 was moved to an alignment closer to the ocean, Oregon Route 42 was extended along the northernmost section and Oregon Route 42S was created along the southernmost section.
