HONOLULU (HawaiiNewsNow) – The Kolekole Pass is officially allowed to be used as an evacuation route in the event of an emergency on West Oahu.

U.S. military and civilian officials signed an updated official memorandum of understanding Wednesday, opening Kolekole Pass for emergency use.

The first document was signed just prior to July 29, 2025, when Hawaii faced a tsunami warning, and the pass was opened for West Oahu residents to evacuate.

Nearly 500 vehicles made their way through the pass that day as many evacuated the Leeward Coast, officials said.

Maj. Gen. James Batholomees, U.S. Army Commander, Hawaii, was joined by his counterparts from Joint Base Pearl Harbor-Hickam and the state Department of Transportation officers for Wednesday’s signing.

Batholomees said he took command the day before the tsunami warning.

“The next day, the first order that I had the blessing of giving was in conjunction with the Navy opening the pass during the tsunami,” he said.

Kupuna from the Leeward Coast also attended the signing, saying they were happy for a much-needed secondary route in the event that Farrington Highway is shut down.

Leeward Coast resident William Aila recalled when Farrington Highway was closed for 11 days due to Hurricane Iwa in 1982.

“We need an opportunity to bring in first aid, to bring in food, and to bring in other emergency supplies,” said Aila.

Officials say they are committed to conducting a mass evacuation rehearsal using Kolekole Pass every year.

Ed Sniffen, director of the state Department of Transportation, said it’s the key to a successful activation to use the route.

“The road is safe,” said Sniffen. “When we rode through this, and we did this twice with large operations, the road is safe.”

He added, “That being said, there are improvements that we still want to make.”

HDOT continues to work with the U.S. Army and U.S. Navy on upgrading the roadway, which may total $20 million in improvements.
