Before 1975, Honolulu's main outdoor stadium had been Honolulu Stadium, a wooden stadium on King Street. However, it had reached the end of its useful life by the 1960s, and was well below the standards for Triple-A baseball. The need for a new stadium was hastened by the move of the Hawaii Rainbows football program to NCAA Division I. Located west of downtown Honolulu and north of Honolulu International Airport, Aloha Stadium was constructed in 1975 at a cost of $37 million. Constructed of steel, the stadium was nicknamed the "Metal Mecca". The baseball field is aligned north-northwest (home plate to centerfield), as is the football field.
