Board of Water Supply crews finished repairs to the 24-inch water main that broke on Kalanianaole Highway early Saturday. Officials expect all eastbound lanes to be open by noon today, the agency said.
The pipe was repaired as of 4:30 a.m. Tuesday, according to BWS. Crews are working on backfilling the area around the pipe, filling in the excavated area and prepping for paving. Additionally, crews are flushing the line and testing the water.
Officials reopened a second lane from 2 p.m. to 9 p.m. Tuesday on the highway for eastbound commuters. Crews then closed the second lane to continue repairs.
Officials have implemented a traffic mitigation plan that will allow vehicles traveling eastbound in the afternoon peak hours additional green light access through the Ainakoa Avenue intersection. The state Department of Transportation has placed message boards to alert motorists of lane closures and road work. Additionally, DOT has suspended all road construction projects on major arteries in East Honolulu and Waimanalo until further notice.
The city Department of Transportation plans to monitor traffic lights and make adjustments as needed. Honolulu police will also direct traffic through the area this afternoon.
Crews have been working since Saturday to fix the pipe, which is made of cast iron and was installed in 1969. The broken water main on the highway between Kilauea Avenue and Waikui Street caused gridlock over the weekend. Repairs had been expected to be completed by Thursday.
