HILO, Hawaii — The Hawaii County Department of Public Works announced a safety enhancement project will take place along Waipio Valley Road from May 9 to May 10.

Work on the project will occur between 8:30 a.m. and 3 p.m. with the goal to improve road safety and ensure long-term integrity for road users, according to a county news release.

Geolabs, a geotechnical engineering firm, will conduct boring work, drilling into the road to evaluate the soil and rock composition and assess the stability of the road’s foundation. Findings will help guide future improvements to ensure the durability of the road and its ability to withstand nature and heavy use.

Boring will take place in four sites along Waipio Valley Road with brief closures of 15 to 20 minutes affecting traffic as equipment is moved from each site.

During the project, there will be single-lane closures with flaggers stationed to manage traffic flow and ensure the safety of motorists and workers.
