UPDATE:

Repairs to the Pali Highway will continue through November. Crews will continue repairs along the busy highway 12 hours a day, 7 days a week. 
 
“We're working really hard to make sure that we get this back as soon as possible,” Ed Sniffen, State Department of Transportation, said. 
 
Starting August 1 from Sunday to Friday, the Honolulu-bound lanes will be open from 5 - 11:30 a.m. From 12:30 - 7 p.m., the contraflow will switch over for traffic towards Kailua. 
 
Crews are starting to install a new 80 feet structure that extends from the Honolulu Bound tunnel to hopefully catch any debris that falls from above. 
 
Officials say the highway will reopen in both directions on September 1 from 5 a.m. - 7 p.m. Roads won't be back to normal until the end of November because crews still have repair work to do around the slope towards Kaneohe.  
 
"We would always love to work during the day but we know that's the time frame the public needs for their mobility needs. We're trying to strike that balance of how we can get the work done but also make sure the public has mobility,” Sniffen said. 
 
The original rock slide that came down in February slid again from heavy rain last week. 
 
"That water pressure that comes in, espically on high volumes of storm water comes through starts building up. When water pressure builds up high enough near edges of the slope, it starts to blow things out,” Sniffen said. 
 
Workers installed anchors on the slope for now until the permanent fix. DOT will be using over a hundred nails made of steel, known as soil nails and mesh netting along the face of the slope that will hopefully stablize the area permanently. 
 
A silver lining from the land slides is that an original repaving project along the highway is set to finish six months earlier because crews can work concurrently on both projects. That includes resurfacing the pavement and replacing street lights. 
 
The entire project is still on track to cost around $21 million. DOT says federal dollars is expected to pay for 80 percent of it. The state pays for the rest.

The Hawaii Department of Transportation announces that beginning August 1, 2019, access hours to the Pali Highway will be extended. The new schedule will be:

Beginning August 1, 2019, Sunday through Friday (closed on Saturday and State Holidays):

Honolulu bound AM contraflow: 5 a.m. to 11:30 a.m.

Kailua/Kaneohe bound PM access: 12:30 p.m. to 7 p.m.

However, due to the record rainfall on June 25, HDOT has decided to protect additional slopes in the area. The design of the additional work is being finalized but will likely involve the installation of additional catchment fencing and soil nail anchor systems.

The design of the soil nail anchor system that was being installed on the slope on the Kailua side of the tunnels is being modified to include longer soil nails. The slope is currently covered with temporary erosion control matting.

According to HDOT, it anticipates opening both directions of Pali Highway between 5 a.m. and 7 p.m. Sunday through Friday in September once the new tunnel structure protecting the Honolulu bound lanes is completed.

Night work will be necessary through November and single lane daytime closures will be used sparingly after September to complete the additional slope protections and the Pali Highway improvements. All construction is weather permitting.

“We appreciate everyone’s patience as we work to protect Pali Highway,” Hawaii Department of Transportation Deputy Director for Highways, Ed Sniffen, said. “Following completion of the protections we have been able to put in place thanks to FHWA’s Emergency Relief program and the emergency funding from the State Legislature, we fully expect that Pali Highway will be more resilient and dependable in severe weather events.”
