The Hawaii Department of Transportation says crews are currently working on installing a mesh system “to stabilize the slope” between the Pali Tunnels and to repair the damaged electrical building between the tunnels.

A contractor is also installing an attenuator system between Old Pali Road and the highway.

The downtown-to-Windward Oahu artery was closed in February following landslides at the tunnel area.

Traffic access is limited to Monday through Friday Honolulu-bound contraflow between 5-9 a.m., and to Kailua/Kaneohe bound lanes between 3-7 p.m.

The estimated cost of the attenuator, tunnel rockfall mitigation system and emergency work to date is $20 million.

The DOT has requested Federal Highway Administration Emergency Relief

The work is not expected to be completed until late August.
