Geography

Halawa is located at 21°22′39″N 157°55′22″W / 21.37750°N 157.92278°W / 21.37750; -157.92278 (21.377633, -157.922759).

According to the United States Census Bureau, the CDP has a total area of 2.3 square miles (6.0 km), all land.

The route of H-3 extends from its western terminus with east–west Moanalua Freeway (H-201; connecting eastward to Honolulu or westward to H-1 and Aiea) to the 1100-foot (335-m) elevation entrance into the Tetsuo Harano Tunnels, penetrating the Ko‘olau crest. The freeway continues beyond to Kaneohe on windward Oahu.

A significant proportion of H-3 within the valley is carried on the Windward Viaducts; although very expensive to construct, the viaduct is the only way to construct a freeway of this magnitude through such a narrow valley without flooding and destabilization concerns; it is also believed to offer some returns in terms of preservation of both archeological sites and stream ecology.
