The three right-most lanes of the H-1 Freeway Airport Viaduct will be closed in the eastbound direction at night this week between the Nimitz Highway/Pearl Harbor/Hickam Air Force Base off-ramp (Exit 15) and the Keehi Interchange for concrete pavement repair work, the state Department of Transportation said.

The lanes will be closed nightly from 6 p.m. to 5 a.m. tonight through Friday morning. All on- and off-ramps will remain open. The speed limit near the repair area will be reduced to 15 mph to minimize vibrations while the fast-forming concrete cures.

There may also be single lane closures on Valkenburgh Street during these hours.
