All lanes are open again this morning in Waikiki after crews finished repairing a water main break near Kuhio and Royal Hawaiian avenues last night.

Four Waikiki businesses lost water and Royal Hawaiian Avenue looked like a river after a 12-inch water main broke on Monday.

Crews restored water early yesterday and had laid down concrete and asphalt by 7 p.m., said Board of Water Supply spokesman Keoni Mattos. They had to remove debris before reopening all lanes.

Royal Hawaiian Avenue between Kuhio Avenue and Waikolu Way was closed for most of the day because of the break. One lane of Kuhio Avenue was also closed but reopened before 7 p.m. 

 Because of the size of the break, the work took longer than expected, Mattos said. 

He said it will likely be several weeks before the cause of the main break can be determined. The main was relatively new, replaced in 2003.

A claims specialist from the Board of Water Supply was out gathering information on damage from businesses who were flooded. Mattos said other affected businesses can call the board at 748-5000.
