All concrete retaining walls on the project have been completed and backfilled. Gravity sewer and reclaimed utility mainline installation has been completed excluding a small portion at the National Park. The mainline for both these utilities are expected to be completed in the near future through coordination with the National Park Services. Please continue to check the website for future updates regarding this upcoming work. Sewer force main fragmentation completed this past week, allowing crews to begin excavation and installation of the two force main pipes north of Honokohau Harbor.
North of the Hulikoa Intersection, roadway subgrade and aggregate base course grading has been completed to the Airport excluding Airport and OTEC intersection work. Final preparation of the aggregate base course has been completed this past weekend, allowing asphalt paving to begin Monday, May 22nd. Asphalt base will be placed over the aggregate base from Hulikoa to the end of the project throughout the next three weeks. Asphalt paving operations will require a large amount of construction semi-trucks traveling in and out of the project area. Motorists please use extra caution and patience when driving along the project. Additionally, construction activities will soon be occurring near both the Airport and OTEC intersections. Please be aware of the traffic signs alerting of this work as well as other related construction traffic.
While paving continues, crews will focus on completing the street light and traffic signal utilities on the South segment of the project and begin preparation of the roadway subgrade. Concrete swale construction on the South segment of the project will begin as the utility work begins to wrap up. A small crew will be working on the mauka side of the highway near the National Park entrance to get ahead on drywell installation required in upcoming construction stages.
Please continue to help us keep motorists, pedestrians, and our workers safe by respecting the posted work zone speed limits. As a reminder, a large number of construction related semi-trucks will be driving in and out of the project site and merging with Queen K traffic, please continue to be alert and drive safely during this time.
