We have the latest update from the state, and starting September 4, there is excellent news for residents and visitors wishing to travel from Princeville to Hanalei and beyond. We have been closely following progress since the historic Hanalei Landslide closed the highway in March and as recently as this morning.
After the incident, the road was made partially accessible to the public, including visitors, during set hours. The highway has been limited to one alternating lane during specific hours only, weekdays, with more flexibility on weekends.
Some restrictions will continue until all phases of repairs are completed, which will take significant time.
Updated access to Hanalei effective September 4.
The State DOT said yesterday that it would provide access 24-hours a day starting September 4. There are still restrictions, albeit far less than before. It should then be possible to travel in both directions without significant delay.
The DOT reported last month that all 545 soil nails had been installed to anchor the upper hillside. The completion of the concrete in that area (as seen in the photo) appears completed. The removal of debris and the preparation of the second lane are ongoing. In the past week, we noticed that the second lane had been cleared, and some ditch alongside that lane has been dug. How that ditch will be used isn’t clear. Drainage for the upper slope is complete.
In the next phase of repairs, following the second lane being restored on September 4, drainage for the lower portion of the slope will be implemented, while repairs to manage effluent from the ancient water tunnel and soil nails and wire mesh below the highway level will also be completed. That phase is still in design, and we anticipate that it will take many months, if not longer, for the entire process to be completed.
Tips for accessing Hanalei and beyond starting September 4.
For this next phase, traffic should be a consideration, while far less than previously, when the road was only open three times per weekday. Our top choices on when to travel from now on are as follows:
- Sunday when there’s no construction or state holidays. Normal traffic flow with both lanes operating continuously, so there should be no backup in either direction, with no wait times.
- Monday-Saturday: 530 pm to 7 am. As with Sundays, both lanes will operate continuously with no delays anticipated.
- Monday-Saturday: 7 am to 530 pm. Expect only brief delays, as there will be one single-lane operating continuously with alternating traffic directed by a pilot vehicle escort. Note: Before September 4, this was how the road operated on Sundays, and we have only encountered brief delays under those conditions. Those managing the traffic flow have been doing an excellent job. The backup going north usually starts at the entrance to Princeville but moves fast.

Here’s what occurred in March.
An enormous mudslide occurred near the site of an earlier 2018 landslide. This landslide resulted in tens of thousands of cubic yards of mud slid down onto the highway, effectively cutting off regular access for communities of Hanalei, Wainiha, and Haena from the rest of the island.
The mudslide and subsequent road closure took place on the North Shore of Kauai near mile marker 1, approaching the Hanalei Bridge in an area called “Hanalei Hill.” You know this area as the location where you wind down the hill following Princeville shopping center towards Hanalei.
DOT had previously protected the area with mesh slope covering and a rockfall fence to capture debris. This landslide, however, is “Outside of the area we stabilized with soil anchors following the 2018 Floods. The current slide is much deeper than the previous event at this location, but thankfully not as wide.” That according to the State DOT.
The state said that the most recent mudslide is related to an irrigation tunnel dating back to the 1800s. HDOT worked to identify the water sources feeding into the tunnel.
The DOT said, “Monitoring of the road above the Hanalei Hill landslide, Kuhio Highway between Kolopua Apartments and Hanalei Plantation Road, will continue and HDOT will maintain this closure out of an abundance of caution.”

Thank you for this great information. We’re staying in Westin Princeville Villas from 13-25 October. Can you clarify how the weekday guided vehicle traffic works? We’re considering an weekday 11:30 boat tour of the Na Pali coast departing from Hanalei. Their website says we need to take “morning convoy” (5:30 am-7:45 am) which is a little confusing. If an escort vehicle is guiding traffic in alternating directions during the day couldn’t we leave later in the morning? Any estimates on how long the wait is from the Westin Resort to get past the construction zone? Sorry for all the questions. We’ve been researching and this site seems to have the best information.
Hi Bill.
There has been little or no delay recently. From our experience, in the worst case, plan on an extra 30 minutes for road work.
Aloha.
Thanks so much for the quick reply!
We just returned from a week in Hanalei. Now with one-way traffic control during the weekdays we were never delayed more than about five minutes. On the weekend there was one lane open in each direction so zero delay.
Thank you for all you do for Hawaii and Kauai!
Thank you so much for the information. We’ll be staying for a week in Hanalei at the end of September and were considering booking a hotel near Lihue for our last night due to the road restrictions and our flight times. This means we can stay in beautiful Hanalei and not worry about missing the convoy. Excellent news!
KIM W.. I would anyway… just because you can get out of Hanalei doesn’t mean you can get thru Kapa’a! Or across the bridge if it rains. Or counting on there not being an accident. Etc etc etc. you get the point!
WOW! First time I’m seeing the initial damage. No wonder it’s taken so long to repair! Thanks guys!
Hi Barbara.
Thanks. Nearly 500 comments to date. Wow!
Aloha.
Good and bad. We were looking forward to less crowded beach during weekdays. Oh well.
Great news yesterday from HIDot. Starting September 4th one lane will be open constantly with escort cars alternating directions! No more windows of opening times!
I believe this is several weeks earlier than estimated.
Yes, the DOT website says 12:30-2 pm (PV side first) on Wednesdays. I was just throwing in my 2 dollars as to why the “Hanalei Town” website may be outdated. I not familiar with that site.
Hi David.
Got it. We are not familiar with it either.
Aloha.
Unless they go back to mandatory quarantine for all arrivals, we will be there starting next Wednesday (Sep 1) through the 23rd. We will become very familiar with the slope situation, since we live out in Wainiha. Neighbors tell me they’d be surprised if it fully reopens before the end of the year. The HIDOT speculated by end of September at one point, but HIDOT has no credibility in our neighborhood with respect to predicted road re-openings. After the April 2018 washouts, it was going to be repaired by end of July, then by end of October, then by the end of year, then they quit giving any dates, and it eventually happened in June 2019, although the bridges weren’t finished for many months after that. Good times.
Hi David.
You will see that the other (currently blocked) lane had been cleared recently. The lower slope however will take a long time to complete and we’ve continued to see debris coming down. It sure doesn’t look ready to open anytime soon. The way things roll here it could go either way, next month or next year.
Aloha
Thank you for this helpful information.
There’s a discrepancy in convoy times on Wednesday afternoon between what you posted and what is posted on the “Hanalei Town” website. You have 12:30-2:00 pm and they have 12:00-1:30 pm.
Can you confirm which is correct? And what’s so special about Wednesdays?
Mahalo,
Jerry
Hi Jerry.
The state says 1230 to 2. Wednesdays are different due to school hours.
Aloha.
The Wed school hours were slightly adjusted. I forget if from 12:30 to 12 or the other way around. Maybe when school started back up in July they changed it back?? (HI has “year-round” school schedule) Kids get Wed afternoons off.
Hi David.
On just checking, that if what the state says.
Aloha.
Aloha. We will finally be revisiting Kauai end of October so would appreciate updates, especially about access to Hanalei. We like to visit there often so that would be great information.
Mahalo.
Hi Marys.
Yes, do stay in touch. There are no updates to the road. To us it does not look like it will open for October, but perhaps we will be pleasantly surprised. Stay tuned.
Aloha.
