Hawaii's Interstate H-3 project is the winner of the 1998 Outstanding Civil Engineering Achievement Award. The highway, built to alleviate commuter congestion and to link several military bases, connects the windward and leeward sides of Oahu, Hawaii's largest and most populous island. The 16 mi, four-lane roadway crosses undeveloped, environmentally sensitive terrain and important archaeological and cultural sites and burrows nearly a mile through the scenic but rugged Koolau Mountains in a twin-bore tunnel. Soaring viaducts carry the route for several miles, offering motorists breathtaking views of Oahu's natural beauty. The $1.3 billion project, completed and opened to traffic more than 30 years after initial planning began, is the largest public construction project in the state's history.
