Highway 20 from 22 down to Sweet Home is doable. However, be prepared for some sharp curves and narrow roads with little or no shoulders. We typically just take 22 to Salem. From there you can either continue on 22 over to 18 to Lincoln City, or go south on I-5 down to 34 and over to reconnect with 20 to Newport. About 20 miles longer on 22, but a much better highway with less sharp curves.
