PORTLAND SPEEDWAY
Description Clay oval circuit, slighly banked. Not to be confused with Portland International Raceway.
The circuit was closed in 2002 after 77 years, so I think it was opened in 1925. It seems that for a period it has been a paved track. Moreover, sources don’t agree about track length.
