HONOLULU (KHON2) — The collapse, which included a portion of the makai lane, happened north of Pokiwai Bridge.
Thankfully, no one was hurt in the collapse, but it has nearby residents concerned.
Crews from the Department of Transportation were sent to the scene last night, but because of the darkness, they weren’t able to tell if the road was stable at the time.
Contraflow lasted until 2 p.m. Saturday.
The DOT said they will begin emergency repairs to that stretch of highway on Sunday.
However, this isn’t the first time this portion of highway has needed emergency repairs.
In April, crews fixed up a portion of the highway just 200 yards away near Hulahula Place.
Some Hauula residents are happy that new guardrails went up near Hulahula Place but after last night’s collapse they say more needs to be done to ensure safety when driving through the area.
“Personally, when I drive down I’m keeping a really sharp eye on the right side of the roadway near that white line because I don’t want to fall off into the ocean,” said Hauula resident Derrick Pressley.
He points out the amount of traffic that passes through the area daily.
“We’re very concerned about safety,” he said.
“The roadway fell last night in the middle of the evening. Simple. Somebody could have gotten hurt,” he said.
The DOT said the emergency contractor will spend the next week making emergency repairs to the area.
“We’re going to do this stretch out here, and we’re going to hit areas about 300 feet behind it to make sure we can stabilize it as much as possible,” said Ed Sniffen, Deputy Director of Highways.
However, a long term solution to fix the erosion issue has not yet been decided on.
“The long term solution is to determine what we can afford, that’s the big thing. The great thing about Hawaii is that we have these great beachside roads we have belts that make it work, but because of it they’re so close to the ocean that they’re affected by the shoreline daily,” Sniffen said.
“As we continue to stabilize there are going to be areas that destabilize and we’ll fix those too and while we’re doing that we’re planning with other agencies to determine where this road will go in the future. Will it be here? Will it be elevated? Will it move mauka? If so, where? So we have to work with other agencies to make that determination because it can’t just be a DOT thing,” he said.
The DOT believes heavy rains are what caused the collapse.
Repairs to approximately 270-feet of undermined shoulder will begin at 7 a.m. Sunday, Jan. 5, and will continue through the week of Jan. 6-10. Work hours will be from 7 a.m. to 6:30 p.m., daily. During work hours, the makai lane will be closed and traffic in both directions will be maintained through contraflow.
Outside of work hours, the makai (oceanside) lane will be reopened.
Crews will stabilize the highway by placing filter fabric, filling in the undermined area with cobblestones, topping off the cobble with controlled low-strength material (CLSM) cement, and repaving the highway.
Previously scheduled permit work in Hauula at Hulahula Place and Kaipapau Loop will be canceled.
