Lane closures for Honolulu's rail project begins Monday at a busy Pearl City intersection.
Last week, the Honolulu Authority for Rapid Transportation tested the soil before breaking ground for the rail columns.
Starting Monday, two westbound lanes of Kamehameha Highway between Waimano Home Road and Kuala Street will be closed every day until Friday from 10 p.m. through 7 a.m. One eastbound lane will also be closed between 8 a.m. and 3:30 p.m.
The construction will be in front of the Pearl Highlands Center.
Also, the right westbound lane of the highway near Acacia Road will be closed 24 hours a day for the entire week. HART officials say the closure is necessary bus stop relocation.
"Anytime you see a bus stop, there's usually a concrete and that's usually to accommodate the heavy bus vehicles when they stop," said HART spokesman Scott Ishikawa. "But, unfortunately, for concrete work, it goes beyond the 8-hour shift."
Officials say, for safety reasons, they're restricting U-turns from the eastbound direction of Kamehameha Highway at Acacia Road for the week.
The state Department of Transportation has given the city jurisdiction over Kamehameha Highway and Farrington Highway through Waipahu and Pearl City during rail construction.
