....actually the fastest part of their whole trip in portland will be driving 84 east to Edgefield. Portland traffic has become unmanageable for any weekday traffic any time of the day. Oregon I-5 traffic is also bad. The only down time is Between Cottage Grove and Roseburg. No relief till south of Ashland. And with the weather system changes in oregon, chances are slim that they will have no snow, so that is a change for the good travel time, but not so good for drought , but Semi truck traffic has become a deterrent to any fast traveling in Oregon
