Project Information
The Hawaii Department of Transportation (HDOT) Highways Division has conducted a study to determine the long-term vision and management for Farrington Highway Corridor between Nanakuli and Makaha. The study analyzes and identifies short-term (6 months – 2 years) and long-term (2 to 20 or more years) multimodal solutions that address safety, traffic congestion, and resilience. The study was completed with multiple community engagement points, summarized below. The study should be referenced and considered when programming future safety, congestion, and resiliency improvements on Farrington Highway (Route 93) and through its corridor.
