The Pali Highway is scheduled for nightly lane closures in the Honolulu-bound direction beginning 8 p.m. Sunday, which will continue through the week until 5 a.m. Friday for an improvement project, according to state transportation officials.

Next week’s overnight lane closures are as follows:

>> Honolulu-bound: All lanes closed between Kamehameha Highway and Waokanaka Street. Motorists may use the Likelike Highway, H-3 freeway, or Kalanianaole Highway as alternate routes.

>> Kailua-bound: Left lane closed between Waokanaka Street and the Pali Tunnels.

>> Intermittent two-lane closure between Waokanaka Street and Nuuanu Pali Drive.

Crews will be performing median work, drainage improvements and restriping. No crosswalks or sidewalks will be closed.

Electronic message boards will be posted, and special-duty police officers will be on-site to assist with traffic control. Emergency vehicles, first responders, and TheBus will be notified of the roadwork and allowed through the closure.

The 8 p.m.-to-5 a.m. closures will occur weekly (Sunday night through Friday morning) for about a year, with an estimated completion of March 2019.

The Pali Highway improvement project includes the installation of LED light fixtures from Vineyard Boulevard to Castle Junction, and resurfacing from Waokanaka Street to Castle Junction, including the parallel Waokanaka Street and the Pali Highway/Waokanaka Street intersection.

Lane closure information associated with the project is updated weekly on the HDOT website under road closures. Construction updates, schedules and maps are also available at PaliHighway.org.
