The Board of Water Supply said all lanes of Farrington Highway in Nanakuli have been reopened today, following a water main break that created major traffic congestion for Leeward Coast residents.

All lanes of the roadway near Pohakunui Avenue were reopened shortly before 5 p.m.

Crews working around the clock finished repairs to the 24-inch main below Farrington Highway at about 7:45 a.m. today. The eastbound lanes, however, remained closed until a contractor could finish repaving the road.

This afternoon, the board asked residents from Honokai Hale to Makaha to continue to use water sparingly and for priority needs only, such as for cooking, drinking, and personal hygiene. The water restriction should last until further notice to allow the water system to recover.

The PVC main broke around 6:30 p.m. Thursday, shutting down lanes and slowing the evening commute to a crawl.

A 20-foot crack sent streams of water gushing into the ocean, and police closed all eastbound lanes between Pohakunui and Kahe Power Plant.

The water main supplies 60 percent of water to the Leeward Coast.
