Connecting Pearl Harbor and Kaneohe Marine Air Corps Station is Hawaii's new interstate highway (H-3)--a $1 billion project with a 30-year history. Planning for H-3 began in 1966, but stalled abruptly when new federal regulations resulted in nearly 20 years of litigation over historic and environmental concerns. This article provides information about the viaducts, bridges, cut-and-cover tunnel, and twin-bore tunnel that comprise the 24-km (15-mi) interstate. The centerpiece of H-3 is the state-of-the-art, twin-bore tunnel, which cuts through one of Hawaii's oldest volcanos. Excavation and tunnel construction are described in detail. Exiting the tunnel toward Honolulu, twin viaducts extend 2 km (1.2 mi) over rugged terrain. Construction of the segmental viaducts is described as well. H-3 is scheduled for completion in late 1996.
