A traffic nightmare for the Leeward Coast threatened to stretch into a third day Monday as Board of Water Supply crews suspended repairs on a broken water main that closed a section of Farrington Highway.

The situation grew worse on Sunday, when repair crews inadvertantly damaged a sewer line under the water main. That put repairs to the water main on hold until the sewer line could be fixed, according to the Board of Water Supply.

There was no sewage spill, the agency said.

There was also no word on when the road might reopen.

Meanwhile, water was cut off to much of the coast from Honokai Hale to Waianae, and the water board urged customers to use water sparingly — that is, for cooking, drinking and personal hygiene only. The break is on a transmission line servicing the Leeward Coast with roughly 60 percent of its water supply, and it will not be in service while under repair, BWS said in a news release.

But the main headache was traffic, which was bumper to bumper for miles Saturday and Sunday leading into Nanakuli from town.

The 24-inch main broke at 4:30 p.m. Saturday at 89-318 Farrington Highway near Nanakuli Beach Park, prompting the closure of the main thoroughfare between Piliokahi to Nanakuli avenues.

Special duty officers assisted in redirecting traffic to a nearby bypass bridge where one lane was open in each direction. 

On Sunday, police opened bypass roads from Helelua Street to Lualualei Naval Road to Hakimo Road. 

The BWS apologized for inconvenience to the community.
