Both lanes of Alii Drive will shift Tuesday onto a temporary bridge at Tiki’s Surf Spot as work continues on the Alii Drive Culvert Replacement Project.
Starting Tuesday, the Hawaii County Department of Public Works will shift both north and southbound traffic on Alii Drive onto the temporary bypass bridge adjacent to the Kona Tiki Hotel. The traffic pattern is expected to be in place 24 hours a day until May 2021.
Motorists are advised that the speed limit has been reduced to 15 mph through the construction/detour zone and that they should drive with extra caution in the work zone. Pedestrians and cyclists 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.
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 $8.97 million culvert replacement project has an estimated completion date of May 2021.
