Interstate 84 (west) starts in the Portland metropolitan area, I-84 is sometimes referred to as the Banfield Freeway or simply "the Banfield", although the official name is the Banfield Expressway. The freeway is named after Thomas H. Banfield, chairman of the Oregon Transportation Commission from 1943-1950.
East of Pendleton, Oregon, I-84 traverses the infamous Cabbage Hill grade (a 6% grade). This grade is legendary for the fact that the westbound lanes switchback twice on its descent into Pendleton. Eastbound lanes feature what are the tightest curves on the Interstate system, even though those curves are on the uphill (eastbound) direction. This grade is also well known due to the fact that it features such a great distance between eastbound and westbound lanes, nearly 2 miles between directions of travel at points.
