The shoulder lane of H-2 Freeway northbound at the Wahiawa off-ramp (Exit 8) will be closed from 8:30 a.m. to 2:30 p.m. today.

The closure will allow the state Department of Transportation to replace shoulder reflectors.

The ramp itself will remain open during the work hours.

Motorists are advised to use caution while driving through the work areas and to allow for extra travel time. Roadwork is weather-permitting.
