PORTLAND INTERNATIONAL RACEWAY
Description At the end of Second Worls War Portland Jaycees, a local newspaper, proposed to build a street circuit at Vanport, a town abandoned after a flood in 1948. The land was sold in 1960 to City of Portland by Army Corps and in June 1961 the circuit hosted it first race, Rose Cup. In the following years it was used for kart, motorbike and Dragster races, the latter of course on the long start/finish straight.
First international race, a Trans Am race, was held in 1972. In 1978 it hosted its first IMSA race and in 1984 its first Cart (now Champ Car) race, since then always on schedule.

As rarely happens in USA, now the owner of thre track is still the city of Portland, that operate through an Entreprise Found.

The trak has 12 bends, many of them are in quick succession and driver consider them as a single long bend. In 1980s a chican was added approx at 2/3 of the main straight. In 1992 this chicane was changed into Festival Loop, a chicane much slower and narrower than the old one. The latter recently has been repaved in concrete, so drivers has many problems there.

Champ Car encreases its requirements and this area has a low receptivity and for this reason the circuit could lose the race. For this reasonin April 2007 somebody proposed to build a new circuit near Portland. Nevertheless Mayor of Portland told that in this moment no funds are available for build a new circuit, so the only possibility would be to move the race on a new street circuit to be built at Portland

There’s a patch of asfalt on the inside of turn 7 which may be available as a temporary chicane. It could be an unfinished acces road though. All information above provided by google earth only.
