Police are continuing to redirect traffic around a water main break on Farrington Highway in Nanakuli, causing long delays in traffic.

The Board of Water Supply said a 24-inch pipe ruptured at 87-2070 Farrington Highway near the Nanakuli Sack ’N Save yesterday about 11:25 p.m. The cause was not immediately known.

Police are redirecting all traffic onto side streets at Lualualei Naval Road and Helelua Street.

Waianae-bound traffic was backed up for about three miles, passing Ko Olina Resort & Marina and causing an estimated 90-minute wait, a Waianae police sergeant said. Diamond Head-bound traffic was light.

A Board of Water Supply employee said customers in the area may have low water pressure until about 6 tonight.

Road repairs are expected to be completed late tonight.
