Portland International Raceway



Portland International Raceway is built on the former location of the World War II city of Vanport, which was wiped out by a 1948 flood. The Army Corps of Engineers sold the site to the City of Portland in 1960 and in 1961 the first Rose Cup races were held.



Portland International Raceway (PIR) is located in Portland, Oregon's Delta Park complex on the former site of Vanport, just south of the Columbia River.



The track hosts a Champ Car race every year and ICSCC and SCCA road racing and autocross events. The facility includes a drag strip and a motocross track.



The road course is almost perfectly flat and runs clockwise. Two track configurations are possible. One includes a hard chicane at the end of the front straight and involves twelve turns at length of 1.967 miles. Without the chicane, the track has nine turns an a lap length of 1.915 miles.
