Waikaumalo Stream Bridge Closed for Repairs

The department of Public Works will begin repairs to Waikaumalo Stream Bridge in Nīnole, North Hilo the first week of August.  The suggested routes to Waikaumalo Park are Pīhā-Kahuku or old Māmālahoa Highway.

Repairs to the infrastructure necessitate closing the bridge until the scheduled opening in late November or early December.  Poor weather could delay this project.

The $194,795,000 contract awarded to Keauhou-Kona Construction Corp. will also replace the existing water line suspended from the bridge.  A temporary waterline will provide water to residents and remain in service until the new waterline is operational.
