The left lane of H-1 Freeway eastbound will be closed near the Dillingham Boulevard offramp on Monday while workers replace the median crash attenuator.

Crash attenuators are devices, such as sand-filled barrels or collapsible railings, that absorb the impact of an automobile crash.

The lane closure will be from 8:30 a.m. to 2:30 p.m.

Motorists are asked to use caution while driving through the work area and to allow for extra travel time.
