Kāneʻohe's Spring Storms Left One H-3 Ramp Behind. Here's What Has Come Back Around It.

Heading toward town on Kamehameha Highway, you can't take the Halekou Interchange ramp onto Honolulu-bound H-3 right now. Drivers move into the left lane, make a U-turn at the signal for the eastbound H-3 on-ramp, then come back on the Kāneʻohe-bound side and take the right lane onto the westbound ramp from the other direction. That loop is the official detour from the Hawaiʻi Department of Transportation, which also lists Likelike Highway as the other way to reach westbound H-3.
The U-turn has been in place around the clock since mid-June. Much of what the same storms damaged near this interchange has since reopened. Kiʻonaʻole Road is open, the back-road detour through Hoʻomaluhia is over, and the Kāneʻohe Public Library is open again after a much longer wait. The ramp is the piece still closed, and it's the one that connects Kāneʻohe to the rest of the island.
HDOT has published three updates on this repair. The first two both pointed to August for the ramp. The third moved it to mid-October and pushed the overall finish back a month:
| HDOT update | Ramp reopening estimate | Overall repair completion |
|---|---|---|
| May 21, 2026 | Mid-August 2026 | November 2026 |
| June 18, 2026 | August 2026 | November 2026 |
| Sept. 3, 2026 | Mid-October 2026 | December 2026 |
The mid-October estimate came and went. HDOT's Oʻahu lane closure schedule for the week of Oct. 31 through Nov. 6 still lists the Honolulu-bound H-3 on-ramp from Pali-bound Kamehameha Highway as closed 24 hours a day, seven days a week, "for the duration of the emergency culvert repairs." Every HDOT update has carried the same warning that the work is weather permitting and the final date could change.
Small ramps rarely close for months, so here is the cause. According to HDOT's June 18 release, the Kona Lows and heavy rain in March and April caused an underground culvert to fail at the Halekou Interchange along Kiʻonaʻole Road. The roadway lost its structural support, the slope and embankment became unstable, and sections of the culvert were left exposed.
The work started on Kiʻonaʻole Road on the evening of April 20. On June 15, inspectors found more erosion in the pipes and culvert under the westbound H-3 on-ramp and closed the ramp for safety. That's when the 24/7 detour began.
HDOT lists the scope as demolishing the old roadway and culverts, digging a new concrete-lined drainage channel with reinforced box culverts, stabilizing the slope, clearing debris and brush from the existing channel, moving utilities both temporarily and permanently, and rebuilding the road.
The utilities caused the first delay. According to the Kāneʻohe Neighborhood Board meeting record for its spring meeting, the Governor's representative reported that crews found utilities in the work area they hadn't expected. That pushed the schedule back while the utility relocation waited for approval. Since then, crews have worked seven days a week in two shifts: 6:30 a.m. to 5 p.m. and 5 p.m. to 3:30 a.m.
The local road beside the ramp reopened before the ramp did. HDOT reported that Kiʻonaʻole Road reopened to all drivers on Aug. 17, with repairs still going on around it.
That ended a detour that had sent drivers through a botanical garden. While Kiʻonaʻole was closed, the way to Koʻolau Ballrooms was Luluku Road, then through Hoʻomaluhia Botanical Garden on its park access road, coming out at Kiʻonaʻole Road at the H-3 overpass. The city's Handi-Van service was also told to keep using the garden's back road for pickups and drop-offs during the storm repairs. HDOT stopped using that garden route on Aug. 23.
Kiʻonaʻole is open, but it isn't fully back to normal. During work hours, flaggers may switch traffic to contraflow in both directions while crews set and remove concrete forms and pour the channel walls. The current lane closure schedule still lists contraflow on Kionaole Road between Kahiko Street and the H-3 overpass, as the contractor needs it, during both day and night shifts.
Hoʻomaluhia is a garden again, not a bypass. The city lists its hours as 9 a.m. to 4 p.m., closed Thursdays, with the last vehicle entry at 3:30 p.m. and everyone out by 4. It also has three campgrounds with 28 sites, reserved through the city's permit system. The Hoʻomaluhia page is also where the city posts short closures, such as the early-November pedestrian restrictions for palm treatments against coconut rhinoceros beetle, so it's the page to check before a late-afternoon walk.
The ramp's delay looks smaller next to Kāneʻohe Public Library on Kamehameha Highway. The same Neighborhood Board record notes that Rep. Scot Matayoshi said the library had largely reopened after two years closed and a series of delays over electrical issues, off-gassing and ADA parking. HPD allowed two temporary accessible stalls on its neighboring property so the library could open. Limited service resumed Sunday, May 17.
The Hawaiʻi State Public Library System's Kāneʻohe branch page now lists 24 free parking spaces, two accessible spots, computers, Wi-Fi, computer classes, photocopying and test proctoring. Its calendar for the rest of the year includes:
The library notes that program schedules can change.
HDOT's latest estimate puts the end of the culvert work in December. That's the busiest month on the town's calendar.
The 62nd Kāneʻohe Christmas Parade is Saturday, Dec. 5, running from Windward Mall to Castle High School. This year's theme is the foods people love during the holidays and all year round. The parade site invites people to come as volunteers or spectators.
Windward Mall has posted its holiday hours:
Individual stores can set their own hours. The Plenty of Aloha Farmers Market keeps its regular schedule in Center Court, Wednesdays from 2 to 6 p.m. and Sundays from 10 a.m. to 2 p.m., with more than 50 vendors. Its 2026 calendar runs through Wednesday, Dec. 30.
Kāneʻohe Bay Drive has weekday work of its own. In early November, HDOT scheduled alternating single-lane closures and lane shifts between Kamehameha Highway and Puohala Street for topographic surveying. It also scheduled a right-lane closure on the northbound side between Kamehameha Highway and Nanamoana Street for manhole trenching, from 8:30 a.m. to 3 p.m. HDOT updates the lane closure page every week, and it's also the first place a reopened H-3 ramp will drop off the list.
Until it does, the Honolulu-bound trip from this side of Kāneʻohe means either the Halekou U-turn or a drive over to Likelike, and HDOT's own estimate keeps the last of the work going into the same month as the parade.
