Interstate 205, also known as the East Portland Freeway, is a 26.6-mile-long route that spurs off Interstate 5 at Tualatin (south of Portland) and travels north through the east side of the Portland metropolitan area connecting back with I-5 just north of Vancouver, Washington. It was the last of the three Interstate 5 spurs to be completed. It was finished in December 1982.
I-205 is one of the most heavily traveled portions of interstate in Oregon. Average daily traffic on I-205 near its connection with I-84 in Portland is 148,300 vehicles per day.

NEPA Requirements
I-205 was one of the first Oregon highways to successfully follow the requirements of the National Environmental Policy Act of 1969. NEPA required that “…road projects using federal funds must have an Environmental Impact Statement [EIS] detailing the effects of the proposed work,” a requirement that would have major impacts on Oregon’s interstate program.
