On September 1, 2026, Mayor Kimo Alameda signed another continuation of the Waipio Valley Road emergency rules. They are the same rules first adopted on September 15, 2022, and they still carry "the force and effect of law." The new rule rests on the Twenty Fifth Declaration of Emergency. That declaration's emergency period runs from September 3 through November 1, 2026, and the traffic emergency zone continues until February 25, 2027.
Twenty-five declarations can make it sound like the road is simply shut. It isn't. The rule doesn't close Waipio to everyone. It sorts people by what they drive and where they live. A Honokaa resident with the right truck can still make the trip down the 1.4-mile road, which is the only way in and out of the valley. A cousin visiting from Oregon can't walk a single step of it. The renewals look like activity, but they mostly keep that sorting in place while the engineering that might change it is still being designed.
The rule turns on your transmission
The September 2026 text bans three groups outright: all pedestrians, uncovered vehicles "including but not limited to ATVs," and horseback riders. Vehicle access is allowed for three groups: Hawaii County residents, permitted licensed and insured tour operators, and "Native Hawaiians claiming exercise of traditional and/or customary rights."
Being a county resident gets you to the top of the road. Your vehicle decides whether you go down. Every vehicle has to meet all of these conditions:
- Low-range four-wheel drive. The rule says directly that all-wheel drive does not count.
- Gross vehicle weight rating of 10,000 pounds or less. Utility and emergency vehicles are exempt, and so are existing vehicles used to haul agricultural products.
- Four-wheel drive engaged for the entire trip.
- Every passenger seated and belted in an enclosed compartment built for passengers. Nobody rides in the truck bed.
- Makai-bound traffic yields to mauka-bound traffic.
The AWD line is where most people get caught. Plenty of crossovers and SUVs parked along Mamane Street are AWD. Under the rule, an AWD vehicle doesn't qualify no matter where its owner lives. The agricultural exemption on weight matters too. The County's own September 2026 declaration lists farmers who carry crops grown and harvested in Waipio Valley among the road's users, and calls it the valley's only vehicle route in and out.
Two more conditions can override all of the above. Hawaii County Civil Defense, working with the Department of Public Works, can close the road to everyone during significant weather. The road can also be closed or further restricted during active repair or mitigation work. Exemptions outside these categories are up to the mayor. Requests go in writing to the Mayor's Office at 25 Aupuni Street, Suite 2603, in Hilo, and must explain how the road will be used and what safety precautions are in place.
Hosting guests means planning around the rim
Visitors from off-island aren't county residents. Under the current rules they can't walk down or drive themselves. Waipio Valley Shuttle says the same thing in its own guide, where it presents its guided 4WD tour as the way for visitors to reach the valley floor. An August 2026 Hawaii Island visitor guide called it the only commercial tour then running on the valley floor. The County rule names no single company. It requires tour operators to hold a permit from the Mayor's office, and each permit lasts four months. Permits expire on that cycle, so it's best to confirm an operator is currently running before you promise a houseguest the trip.
The lookout at the top of the road is a different matter. The same August 18, 2026 visitor guide lists the rim lookout as free and open to everyone. That is the most recent report we found. It isn't an October County notice, and the County hasn't published an update on lookout facilities. The lookout is also where crews stop traffic. February's survey closure ran from the lookout down to the beach-access road.
How a full closure became a sorting system
The current rules make more sense once you know where they started.
- February 25, 2022. Then-Mayor Mitch Roth declared the road an emergency. The original rule closed it to everyone except valley residents, after a geotechnical evaluation by engineering firm Hart Crowser found an elevated risk of rockfall.
- September 2022. After a community group sued, the rule was relaxed to let Big Island residents and some commercial tour operators use the road in four-wheel-drive vehicles.
- Before July 4, 2023. Phase 1 of the cliff work was finished in under six weeks. Crews removed trees, vegetation, and undercut "scallops" of rock from the top 750 feet of cliff face above the road.
- January 2025. Mayor Alameda signed the 15th declaration.
The 15th declaration ran through March 6, 2025. Twenty months later, in September 2026, the County is on its 25th. That's ten renewals at about one every two months, which fits the September 3 to November 1 emergency period in the latest declaration. Each renewal keeps the rules in force. None of them has changed who can use the road.
Why the renewals keep coming
The rules could change in two ways: through the rest of the construction, or through a new hazard review. The most detailed public account of both dates from January 2025. That month the Tribune-Herald's John Burnett reported that DPW spokeswoman Sherise Kana'e-Kane described the project as still "in its preliminary design stages." She explained the delay this way:
"Gathering geological and topographic information has seen unexpected difficulties due to the terrain and unpredictable weather conditions. We are currently exploring alternative methods for gathering this information."
The work still ahead is large. Phase 2, from plans Honolulu firm Haley & Aldrich drafted in 2022, would treat the next 1,300 feet of cliff in four sub-phases and add metal mesh to catch falling rock. Phase 3 would put rockfall fencing higher up the slope. Both phases would close the road every day while work is underway. An early estimate put the whole project at $6 million, and Kana'e-Kane said the real cost will likely be higher.
One line in that article matters more than the rest for anyone hoping to walk the road again. Kana'e-Kane said the County's first priority would be "to revisit the hazard condition study with the intent of either confirming or hopefully reducing the current access restrictions." In other words, the rules could ease after a new look at the hazard data, without waiting for the new mesh and fencing.
The "alternative methods" appear to have arrived in February 2026. The County announced a subsurface geophysical survey by Geolabs, Inc. for the Waipio Valley Road Safety Improvement project, and the road between the lookout and the beach-access road was closed by day from February 24 to 27. Big Island Video News covered the closure at the time. No public schedule for Phase 2 or Phase 3 has been released since.
The declaration's wording hasn't kept up
The September 2026 declaration says the County "is finishing mitigation work (referred to as Phase 1) which commenced on or about June 1, 2023," and "has plans to perform additional work over the next two (2) years." It also notes that the first community meeting, held October 26, 2022 at the Honokaa gymnasium, discussed a "2 to 3-year construction" schedule.
The Tribune-Herald reported, citing DPW, that Phase 1 was finished before July 4, 2023, and that further construction hadn't started as of January 2025. The most likely reading is that the declaration repeats wording from earlier versions. That means "over the next two years" isn't a reliable countdown from September 2026. The 2-to-3-year schedule from the 2022 meeting is now four years old, and the road is still waiting on its second phase.
The declaration also says more meetings "are planned prior to performing further mitigation activities." The last one it lists was held May 1, 2023. The September rule says DPW will hold public meetings to plan road use during construction and will post updates on its Public Works bulletins page. A meeting notice on that page would be the clearest sign that Phase 2 is close. Another renewal on its own is not.
The current emergency period ends November 1, 2026, so the next declaration is due soon. Until a revised hazard study or a meeting notice comes out, the rules for this fall are the ones above: no walkers, no ATVs, no horses, and county residents may drive down only in a low-range 4WD with every passenger belted inside.
