Improvements to the Hakalau bridge on Hawaiʻi Belt Road near mile post 15.3, will begin on Thursday, September 25.  Work hours will be from 8:30 a.m. to 3 p.m. Monday through Friday.

During this time, lane closures may be necessary during the four-month period and travel speed will be reduced from 55 mph to 45 mph, 24 hours a day, 7 days a week.

Work will include repairs to the base around the foundation of the bridge. When concrete grout is poured, the speed limit for crossing the bridge will be reduced to 25 mph to allow for curing. A notice will be issued when this happens.

The work is being done in preparation for the full bridge rehabilitation project.
