Starting Saturday, Farrington Highway will be closed to traffic in both directions between Kualakai Parkway (North-South Road) and Old Fort Weaver Road Loop for rail construction.
The closure will last through the end of January, rail officials say.
Drivers traveling between East Kapolei and the Ewa/Waipahu region can still to access either side by using either the H-1 Freeway on the north end of Kualakai Parkway, or Kapolei Parkway/Geiger Road on the south end, according the Honolulu Authority for Rapid Transportation.
Closing Farrington there will allow construction crews to relocate utilities and do column work in the roadway, rail officials say.
The full closure on Farrington comes as construction ramps up on the 20-mile rail project. Work has also been causing traffic delays along various stretches of Kamehameha Highway in Pearl City, with closures there during the day and overnight.
