A Department of Hawaiian Homelands water system project in Waimea will affect traffic patterns in the coming weeks.

Enhancements include the addition of a new 1-million gallon water tank to augment the existing 100,000 gallon water tank, and 12- and 16-inch water lines to transport the water to the Lālāmilo subdivision, according to the DHHL.

Traffic will be impacted during some phases of construction on sections of Kawaihae Road and on the South Kohala Distribution Road near the Waimea Transfer station.

Motorists should anticipate delays and alternating lane closures if traveling toward Waimea on Kawaihae Road on August 9 and 10 as contractors work on water lines related to the 1-million gallon water tank. Flashing road signs will also be set up to alert drivers to the approaching work. Work hours on this phase will run from 8:30 a.m. to 3 p.m.

Lane shifts are anticipated on Kawaihae Road from October 11 to December 26, 2011, while South Kohala Distribution Road will experience lane closures during the work day from September 21 through October 4, 2011. Access to the Waimea Transfer Station will remain open.

Work hours are from 7:00 a.m. to 3:30 p.m., Monday through Friday, though crews will open traffic lanes earlier than 3:30 p.m. whenever conditions permit.

Work on the 1 million gallon water tank is projected to be completed by September 2011. The water line work is expected to be completed by June 2012.
