The Board of Water Supply closed all but one lane of Waialae Avenue between 8th and 9th Avenues in both directions at 8:30 a.m. Thursday.  The crews need to bury water lines deeper ahead of the City & County repaving project. Customers in the immediate area may experience temporary water service loss when crews switch over to the new service lines. The work will go through 4:30 p.m. Thursday and likely continue Friday.
