Hawaii Department of Transportation—Nanakuli Contraflow

Farrington Highway in Nanakuli is a busy one, especially during peak afternoon and evening hours (3:30-7 p.m.). The roadway often experienced traffic backups due to vehicles turning left. In order to alleviate some of this congestion, HDOT implemented an $800,000 pilot initiative that added an additional lane of capacity in the westbound direction during that afternoon commute through a 1.5-mile contraflow operation. During the contraflow hours, three lanes are now available to vehicles traveling west, while one lane is traveling east. Additionally, the option for left-hand turns was eliminated during contraflow hours. The end result is a much smoother commute for westbound drivers during the busiest hours of the day, allowing commuters the opportunity to get home faster and safer.
