Kauai’s Hanalei Hill Project: Critical Safety Improvements and Traffic Updates for North Shore Residents

“The Hanalei Hill Slope Stabilization Project has already removed over 16,000 cubic yards of debris from the unstable hillside.”

As we enter a crucial phase of the Hanalei Hill Slope Stabilization Project on Kauai’s Kuhio Highway, we at the Hawaii Department of Transportation (HDOT) are committed to keeping our North Shore residents informed and safe. This comprehensive initiative aims to enhance public safety through innovative soil stabilization techniques and landslide prevention measures. In this blog post, we’ll delve into the project details, traffic updates, and the long-term benefits for our community.

Understanding the Hanalei Hill Slope Stabilization Project

The Hanalei Hill Slope Stabilization Project is a critical infrastructure improvement initiative designed to address longstanding safety concerns along the Kuhio Highway. This project, which spans a 1.6-acre construction zone, is focused on stabilizing the hillside near the Hanalei Bridge, an area historically prone to landslides and erosion.

Key components of the project include:

• Installation of high-tensile steel wire mesh to anchor loose soil
• Implementation of advanced drainage structures
• Repaving of Route 560 between the Hanalei Fire Station and the bridge
• Installation of guardrails and fencing for enhanced safety
• Landscaping with local plants to promote soil stability and preserve the area’s natural beauty

Upcoming Road Closures and Traffic Updates

We understand that road closures can be inconvenient, but they are necessary to ensure the safety of both workers and travelers. Here’s what you need to know about the upcoming intermittent closures on Kuhio Highway:

• Dates: April 1-2, 2025
• Location: Between Hanalei Plantation Road and Ohiki Road
• Closure Times: 30-minute intervals at the bottom of each hour, from 8:30 AM to 4:00 PM
• Reason: To allow helicopter crews to place wire mesh on the hillside

These closures will affect both directions of Kuhio Highway from the Hanalei Fire Station to the Hanalei Bridge. We strongly advise residents and visitors to plan their trips accordingly and expect delays during these times.

Special Shuttle Service to Ease Congestion

To mitigate traffic congestion and provide alternative transportation options, we’ve partnered with The Kauai Bus to operate a special Hanalei shuttle service during the closure days. Here are the details:

• Route: Between Hanalei Neighborhood Center and Princeville Shopping Center
• Operating Hours: 7:15 AM to 8:15 PM
• Connections: Links with the 400 Hanalei to Lihue line and the 500 Lihue to Hanalei routes

This shuttle service is designed to help commuters navigate the temporary inconveniences while we work to improve the highway’s safety and reliability.

Project Progress and Achievements

We’re pleased to report significant progress on the Hanalei Hill Slope Stabilization Project. Over the past 20 months, our dedicated crews have:

• Removed more than 16,000 cubic yards of debris and unstable soil from the slope
• Installed 878 soil nails to anchor the face of the slope to more stable, deeper structures
• Completed drainage improvements at the site of the March 2021 landslide

These achievements mark important milestones in our efforts to ensure long-term safety and stability for the Kuhio Highway.

“Kauai’s Kuhio Highway improvement project, scheduled for completion in November 2025, will span approximately 2.5 years of work.”

Prioritizing Emergency Access

We want to assure our North Shore residents that emergency access remains a top priority throughout this project. In the event of an emergency during road closures, first responders will be given immediate priority access through the construction zone. This commitment ensures that critical services can reach those in need without delay.

Long-Term Benefits for the Community

While we acknowledge the temporary inconveniences caused by this project, it’s important to highlight the long-term benefits for our North Shore community:

• Enhanced Public Safety: The stabilization measures will significantly reduce the risk of landslides and road closures during heavy rainfall events.
• Improved Road Reliability: With better drainage and a more stable hillside, the Kuhio Highway will be less prone to weather-related disruptions.
• Preservation of Natural Beauty: Our landscaping efforts with local plants will help maintain the area’s scenic appeal while improving soil stability.
• Economic Benefits: A more reliable road network will support local businesses and tourism by ensuring consistent access to North Shore attractions.
