HONOLULU – The Hawai‘i Department of Transportation (HDOT) is notifying highway users of lane closures on westbound Kamehameha Highway (Route 99) in ‘Aiea for repairs to the slope under the ‘Aiea Cemetery. This slope was previously covered with shotcrete to prevent erosion. The shotcrete slope developed cracks during the March Kona lows and sloughed off during the April severe weather event.
Work to secure the slope will begin on Monday, April 13, 2026. The schedule is:
- Both lanes of westbound Kamehameha Highway will be closed between the off-ramp to ‘Aiea Access Road (past Aloha Stadium) and the H-201 on-ramp to Kamehameha Highway (before Dixie Grill) beginning at 6 a.m. April 13.
- The left lane heading toward Pearl City will reopen for the evening commute Monday through Friday from 2 p.m. to 8 p.m.
- Estimated completion timing is two weeks.
During the slope repairs, HDOT recommends motorists heading westbound on Kamehameha Highway between ‘Aiea and Pearl City use alternate routes such as the H-1 Freeway, or detour around the closure using the ‘Aiea Access Road onto Moanalua Road, or Salt Lake Boulevard and Kahuapaani Street.
