Schofield Barracks is a United States Army installation and census-designated place (CDP) located in Honolulu and in the Wahiawa District of the Hawaiian island of Oʻahu, Hawaiʻi.East on Wilikina leads to Interstate H-2 and Kamehameha Highway (State Rte.s 80 and 99) to Wahiawā and Mililani Town.According to the United States Census Bureau, the post has a total area of 2.8 square miles (7.3 km2), all of it land.The Main Post area consists of numerous quadrangle-style barracks and unit command structures, most of which have a letter designation.Island Palms is the on-post housing company, which is part of Lend Lease, that is responsible for maintaining the units.Covered concrete pads can provide shelter for units training in the area who do not wish to deal with sleeping in the field.Kolekole Road, which passes through the Enlisted Housing Area and West Post Training Area, leads up to a saddle named Kolekole Pass which allows vehicle traffic to flow between Schofield Barracks and Lualualei Naval Magazine as well as being an intermediate destination for physical training runs by soldiers stationed on Schofield Barracks.A 37-foot, 35-ton steel cross located at Kolekole Pass was dismantled by the Army in 1997 after Hawaii Citizens for the Separation of State and Church filed a federal lawsuit charging the cross, built with public tax dollars in 1962, was a "blatant and obvious violation" of the First Amendment.[10] Sergeant Rodney J. T. Yano Library (Building 560), operated by the United States Army's Family and MWR Programs, is in the area.[12] Owing to a higher elevation, Schofield is slightly cooler year round than Honolulu, but is still well within the realms of a tropical climate.
