The H-1 Freeway on-ramp from Moanalua Road west-bound will be closed, and the two right-most lanes of Moanalua Road west-bound from Ka'ahumanu Street to the H-1 Freeway west-bound on-ramp will be shut down from 9 tonight to 4 a.m. tomorrow.

West-bound motorists are advised to use the H-1 on-ramp off Kamehameha Highway just past the Pearl Highlands Shopping Center.

The closures will allow the Department of Transportation to conduct sign and crash delineator maintenance.
