A broken 12-inch water main Friday night has flooded part of the Kalanianaole Highway, between Nenue Street and West Hind Drive in Aina Haina.

The left west-bound lane will remain closed during the repair over the weekend.

Board of Water Supply crews said they are meeting with state and city agencies to discuss traffic mitigation measures. Motorists are advised to avoid the area and police officers are diverting traffic around the break.

The break was reported shortly before 6 p.m., officials said. About 33 customers will be without water during repair.

A 24-transmission line break in the eastbound direction of Kalanianaole Highway in January crippled weekend traffic in East Oahu and took days to repair.
