I-84 near Pendleton, Oregon

In the U.S. state of Oregon, Interstate 84 travels east-west, following the Columbia River and the rough path of the old Oregon Trail from Portland east to Idaho. For this reason, it is also known as most of the Columbia River Highway No. 2 and all of the Old Oregon Trail Highway No. 6 (see Oregon highways and routes). It also follows along or near U.S. Route 30.

Banfield Expressway

The T.H. Banfield Expressway is the portion of Interstate 84 between its western terminus at Interstate 5 and its intersection at Interstate 205 in Portland, Oregon, United States. The expressway, originally built as part of US 30, is named for T.H. Banfield, a former Oregon state highway commissioner.

Planning and construction

Prior to the creation of the Banfield, surface streets were the only routes from Portland to the country. By the 1950s, the system of surface streets were outdated and city planners were looking for more efficient traffic routes. Under President Dwight D. Eisenhower, the federal government had started providing federal assistance to expressway projects. As a result, planners designed a freeway system in Portland to modernize its outdated system of surface streets. The first step to building this new freeway system was to construct the Banfield, which would stretch from Portland to Troutdale. On October 1, 1955, the Banfield Expressway opened to traffic. It was Oregon's first freeway.^[2]

The highway was rebuilt during the 1980s and the MAX Light Rail line was added along the north side at the same time.

Miscellanea

• The Cabbage Hill grade east of Pendleton is a 6% grade, with several hairpin curves in both directions and a separation between directions of almost 2 miles (3 km).
