ADVISORY - Northbound Traffic Flow Change on Ali‘i Drive - June 17 to July 8, 2020

Northbound Traffic Flow Change on Ali‘i Drive Starting June 17

As progress continues on the Ali‘i Drive Culvert Replacement Project, northbound traffic on Ali‘i Drive in the vicinity of Tiki’s surf spot will be shifted onto a temporary bridge with southbound traffic continuing to use the existing roadway.

 

Kailua-Kona, HI – Motorists who frequently travel on Ali‘i Drive in Kailua-Kona are advised of upcoming changes to traffic flow due to work on the Ali‘i Drive Culvert Replacement Project. The existing double-cell culvert bridging the Waiaha Drainageway on Ali‘i Drive, adjacent to the Kona Tiki Hotel, is being demolished, and a temporary bridge has been installed as crews work on building a new bridge. Starting Wednesday, June 17, 2020, the County of Hawai’i Department of Public Works will shift northbound traffic on Ali‘i Drive onto the temporary bridge with southbound traffic continuing to use the existing lane on Ali‘i Drive. The traffic pattern is expected to be in place 24 hours a day for three weeks, until July 8, weather and construction conditions permitting. 

 

Motorists are advised that the speed limit will be reduced to 15 mph through the construction/detour zone and that they should drive with extra caution in the work zone. Pedestrians on the mauka side of Ali’i Drive will be detoured through the temporary bridge pedestrian walkway. Electronic message boards and road signs will advise motorists of the traffic flow change and speed limit reduction. Please anticipate delays for all Hele-On routes that travel in this area. 

 

Built in 1937, the existing culvert is only 20 feet wide and has become severely corroded due to its proximity and exposure to the shoreline. The new culvert and bridge will have a wider stream flow opening, a longer span and wider lane bridge with wider shoulders for pedestrians and bicyclists while reducing flood hazards in the area. The culvert replacement project has an estimated completion date of May 2021.
