Hawaii’s Department of Transportation plans to begin a more than $50 million upgrade of Kawaihae Harbor next year, including widening Kawaihae Road to add an 875-foot dedicated left-turn and storage lane near the harbor entrance.
According to a draft environmental assessment that anticipated a finding of no significant impact, the project is intended to reduce traffic backups by allowing through-traffic to bypass cargo trucks waiting to enter the harbor.
The work also will add 2.3 acres of cargo yard storage, replace damaged pavement with reinforced concrete, upgrade light poles and fire suppression systems, widen the main gate, and relocate utility poles, fencing, and office and maintenance buildings.
The department said congestion, limited container storage, and aging infrastructure have reduced reliability and efficiency at the harbor. Backups on Kawaihae Road can stretch more than a mile, past the intersection with Queen Ka‘ahumanu Highway, or Highway 19, causing delays for nearby residents, businesses, schools, and beach parks.
The department said final design and bidding will take place this summer. It expects to award the contract early next year, with groundbreaking tentatively set for mid-2027. Construction is expected to take about 24 months and finish by mid-2029.
Shipping container volumes at Kawaihae have risen nearly 75% over the past decade, according to the department, as demand grew and some deliveries shifted from Hilo.
