Overnight closures are necessary to complete the construction of the new rock shed and to finish the paving of Honolulu-bound lanes of the Pali Highway, the state Department of Transportation said Friday.

The work will take place nightly between 8 p.m. and 5 a.m. Sunday through Friday and will require closure of both Honolulu-bound lanes and one lane in the Kailua/Kaneohe-bound direction.

Daytime one lane closures may also be scheduled as needed, says DOT.

“Work is anticipated to be finished in December, weather permitting.”

Why the delay?

DOT says, “To date, 40-percent of planned paving days on the Pali Highway resurfacing project have been rained out. Two paving nights have also been lost as a result of asphalt deliveries hampered by protests at Kalaeloa Harbor.”

On the plus side, the Pali — which was closed because of a rockslide in February — will have extended daytime availability beginning Monday.

It will be open every day from 5 a.m. to 8 p.m. Weekend access will be open from 5 a.m. Saturday through 8 p.m. Sunday.
